From a rural baby to a member of an American scientific research team.
Li Can, 1960, was born in an ordinary peasant family in Zhuwangbao Town, Yongchang County, Gansu Province. 65438-0977 Li Can, who lives in a poor village, decided to study medicine after seeing the hope of going to college, and wanted to be a doctor in the future to serve the local villagers who lacked medicine and medicine. At that time, it was very close to the exam time, so Li Can immediately took the time to review and prepare for the exam. However, due to the difficulties of family life, he can only work during the day and review at night. As a result, his college entrance examination score did not reach the admission score of medical university, and he was finally admitted to the Chemistry Department of Zhangye Normal University because he chose to obey the distribution when filling in his volunteers.
Li Can knew that this learning opportunity was hard-won, so he cherished it very much. Every day, in addition to listening carefully and taking notes in class, he also seized all the time to digest what the teacher taught, previewed the next day's course after class, and then began to read extensively, trying to expand his knowledge. In the second year of school, he began to teach himself postgraduate courses. Study hard, so that Li Can's grades in all subjects are among the best in his class, and he has his own unique views on many issues. Soon, he stood out among his classmates in the same period and became a leader, which was favored by teachers. Before graduation, the school decided to let him stay as a teacher.
After graduation, he stepped onto the three-foot platform, and his solid professional skills and rich knowledge reserves made Li Can's lectures lively and interesting, which was deeply loved by students and highly valued by leaders. 1982, after teaching for two years, he was sent to Shaanxi Normal University for further study. During the further study, Li Can studied hard as always. He soon fell in love with reading. He saw an article entitled Atomic Clusters and Catalysis and Surface Science written by Zhang, a famous chemist in China, one of the founders of catalytic science in China and Dalian Institute of Chemical Physics, Chinese Academy of Sciences. After reading it, Li Can became interested in catalytic science, and immediately decided to apply for a postgraduate degree in Dalian Institute of Chemical Physics.
1983, Li Can knocked on the door of Dalian Institute of Chemical Physics of Chinese Academy of Sciences with excellent results. After comprehensive investigation and careful study, this national scientific research unit made an exception and admitted Li Can, a graduate of Teachers College. Since then, Li Can has joined the scientific research teams in * * * and China.
Forge ahead, fruitful, spread everywhere.
Dalian Institute of Chemical Physics is an important scientific research unit in China. There are many talented people here, many academicians and many famous scientists at home and abroad. When Li Can was allowed to enter here, it was like entering a sacred scientific research hall. When he arrived in Dalian, he didn't appreciate the beautiful natural scenery of this coastal city, didn't taste the romance of the sea, didn't dive into the ocean of knowledge, studied hungrily, and even refused to rest on holidays. In this way, reading at night has become a common practice.
The basic research of catalysis is the main direction of Li Can. During his Ph.D., Professor Otani, a famous scientist in the world of catalysis and a Japanese professor from tokyo institute of technology, visited Dalian Institute of Chemistry and expressed his appreciation for Li Can's research spirit and many opinions. Therefore, under his strong recommendation, Li Can won the UNESCO Science Intensive Training Scholarship, became a doctoral student jointly trained by China and Japan, and went to tokyo institute of technology, Japan for a one-year further study.
During his stay in Japan, Li Can went out early and returned late every day. 12 worked until midnight, and systematically studied the surface chemistry and catalytic performance of rare earth cerium oxide, an important component of automobile exhaust elimination catalyst. The research results were published 8 times in internationally renowned academic journals. His thesis later became the basic document for studying exhaust gas catalysts. Professor exultation spoke highly of Li Can. He said, "Li Can is the best among more than 30 doctoral students I have taken", and when Li Can's one-year study time was about to expire, he actively recommended him to be a postdoctoral fellow in the research center of IBM, but at this time, domestic research work was waiting for Li Can, so he resolutely declined the kindness of Professor Daxi and immediately returned to Dalian Institute of Chemical Engineering to devote himself to intense scientific research.
Due to the remarkable research achievements during his doctoral period, Li Cangang received a grant of 50,000 yuan from the newly established "Youth Science Fund" of the National Natural Science Foundation shortly after 1989 returned to China to support his research on methane oxidation and activation, which was Li Can's first independent scientific research project at that time. This 50,000 yuan is not only an encouragement, but also a timely help, so that he can concentrate. Li Can, who canceled the research funding and actively devoted himself to the research, grasped the key scientific issues of surface oxygen species and methane activation. After three years' efforts, the activated adsorption state and structural distortion of methane formed on the catalyst surface were observed by isotope tracing and high and low temperature in-situ spectroscopy, and dozens of papers were published in various international journals, which quickly attracted the attention of international peers. Later, this achievement won the second prize of natural science of China Academy of Sciences with 1993, and he personally won the "China Young Scientist Award", becoming a rising star in the field of catalysis in Ran Ran.
Since then, Li Can's scientific research has entered the fast lane of development and achieved fruitful results. Using Raman spectroscopy to study catalysts is the basis of the development of catalytic science-an important direction of in-situ characterization of catalysts, which is a very concerned and challenging issue in the world catalytic community. After unremitting efforts, Li Can overcame a series of technical problems, and finally successfully developed the first domestic ultraviolet Raman spectrometer for catalysis and materials research at 1998. Subsequently, he applied this new technology to catalytic research and made progress in catalyst surface carbon, molecular sieve synthesis, heteroatom molecular sieve and oxide equivalence. Among them, the work of identifying skeleton transition metal heteroatoms in heteroatom molecular sieves has been highly praised by the international catalytic academic community and is considered as the most reliable method to identify heteroatoms. Li Can's research achievements in this field have not only published more than 30 papers in international journals, but also won many patents with independent intellectual property rights, and won the second prize of national scientific and technological invention.
At the same time, the research of ultraviolet Raman spectroscopy has also made important achievements. According to the new trend of international catalytic science development and the huge demand of China's national economic development, Li Can has opened up several important research directions in time and made great progress in the research of new catalytic materials and new catalytic reactions. 200 1, he chose the worldwide problem of hydrogen production by photocatalytic decomposition of water with solar energy. At that time, many relatives and friends advised him: "This research is too risky. Anyway, you are famous in the field of catalysis at home and abroad now. Once you fail, your reputation will be affected. Be careful! " Li Can knew that relatives and friends meant well, but he said, "Scientific research will face failure at any time, but I think it is meaningful to challenge a worldwide problem. As a scientific researcher in China, as long as you dare to challenge, even if you fail, it is worthwhile, at least you can accumulate some experience and lessons for your colleagues. " It is precisely because of this spirit of disregarding personal fame and fortune that, with the efforts of 10 years, Li Can led his scientific research team to make great progress in 20 12 years, revealing the essence of improving photocatalysis. Many world-renowned professional magazines such as German Journal of Applied Chemistry and American Chemistry and Engineering News have reported Li Can's research results in a large space.
