Recent,Professor Lan Yagang in the School of Chemistry of our school has gained important research progress in catalytic applications of 锆/铪 oxygen clusters,Published on "Science Bulletin" entitled "Sulfur Atom-Direct Metal-Ligand Synergistic Catalysis In Zirconium/Hafnium-Oxo 2024 European Cup Betting PlatformClusters for Highly AMINE OXIDATION "research paper。Our school is the first completion unit of the paper,The first author of the paper is Sun Shengnan, a doctoral student at the 21st doctoral student of the School of Chemistry of our school。This research has received the National Natural Science Foundation of China,Support of projects such as the youth of the Pearl River Talent Program in Guangdong Province。

锆/铪 The characteristics of easy hydrolysis and its relatively inert metal reactivity greatly hinders the structural expansion and performance application of its metal matched objects。The work aims to expand the catalytic application of the matched components with 锆/铪 elements and UEFA EURO 2024 Qualifying Match Result Bettingimprove its catalytic performance。In the text, a strategy of using functional ligands to coordinate metal activity sites to jointly catalyze to complete specific reactions to further improve catalytic performance。In this job,Through ligand engineering,Building two stable 锆/铪 oxygen clusters (ZR9-TC4A and HF9-TC4A) was constructed with 4-Shu Dinglin sulfur cup aromatics (H4TC4A) ligands.,Among them, the unsaturated supporting sulfur atoms on the TC4A4 − can produce a strong metal-ligand synergy with nearby active metal 锆/铪 铪。

Experimental and theoretical calculation results indicate,These 锆/铪 oxygen clusters are used as catalysts European Cup Reliable Betting Platformfor amine oxidative reactions,It can achieve efficient substrate conversion rate and product selectivity through the synergies between two metals and ligands: (1) Efficient photocatalytic amine oxidation reactions through the synergies of dual active sites,Among them, the sulfur atom site on the TC4A4− ligand via photocopic acupoint oxidation amine,Optic e -reduction oxygen molecules on the metal active site; (2) Complete the aniline oxidation response through the synergistic catalyst of adjacent metal ligands,Among them, the sulfur atom site on the ligand is adsorbed to be closer to the metallic activity site,Then oxidant free radical oxidation activated by the metal site。

This job is an important feasibility strategy for the later design high -performance 锆/cymbal base catalyst and develop more catalytic reaction types。
