China University of Technology established nanocatalyst stability theory
According to 上海贵族宝贝桑拿会所 the University of China Science and Technology, the reporter learned from China University of Science and Technology. After eight years of research, combined with large data and first principles, the school proposed and established the general theory of nanocatalyst growth kinetics, which is a rational design and screening. Stable under conditions, anti-sintered nano catalysts laid an important scientific foundation.
Related research results were published on November 5th.
For industrial practice, the stability of nano catalysts is becoming an industrialized bottleneck. It is the problem of "life and death" in achieving high-efficiency chemical production, energy and environmental catalysis and "double carbon" target implementation.
Industrial catalysts derived by industrial catalysts represented by a thermally or chemically-induced nanocatalyst in the world, replaced or regenerated costs reached tens of millions 宝山区419在哪里 of yuan. The noble metal catalyst is increasingly climbed, further aggravating the urgency of delaying its inactivation. At present, the predictive theory and general principles of nano-catalyst stability are still in its infancy, resulting in an inevitable experiment with expensive catalyst life at several years, and highly delayed highly active nanocatalyst industrial conversion.
Therefore, the rational design of a robust nanocatalyst is to have important scientific and economic value in the field of nanocatalytic. Dr. Hu Sui, Professor Li Wei, and Dr. Hu Sui Lei binds to the first-character principle, and actively explores the basic principles of the growth of nanomaterial growth with thermal or chemical induced nanocatalysts. Analysis of the interaction relationship between metal and carriers in metal nanocatalysts, 上海宝山区小巷子找乐子 with atomic adsorption energy, nanoparticle adhesion energy is scaled, and the relationship between interaction and stability is established from the theoretical level, that is, metal nanocatalysts and carriers The role can neither it is too strong, otherwise it will be inactivated in the way of Austvalue; it is not too weak, otherwise it will lead to inactivation of the mechanism of particle migration and collision; only interaction moderate, the stability of metal nanocatalysts Sex up to optimal. They also proposed and developed high-throughput screening strategies that utilize dual function carriers to break scale relationship restrictions, providing a possible design and prediction of super stable nanocatalysts.
