Zhongyi Liu is a full Professor at Zhengzhou University's College of Chemistry. He obtained his doctorate from Zhengzhou University at 2008. He mainly focuses on the precise regulation of the structure and properties of catalysts at the nanoscale and at the atomic-molecular level, and studies their catalytic hydrogenation and hydrogen production functions. The research focuses on catalytic hydrogenation, hydrogen energy and electrochemical energy storage related nano-catalyzed materials and in situ characterization of catalysis. He presided over the project of selective hydrogenation of benzene to cyclohexene, which broke the technical monopoly of Japan and promoted more than 10 sets in China, occupying 100% of the market. He has published more than 80 SCI papers as the first or corresponding authors. At present, in cooperation with enterprises, he has set up an industrial plant for catalytic hydrogenation of 50,000 tons of phthalic plasticizer to produce cyclohexane-type plasticizer.
