This is the homepage of the Prof. Murayama’s Group of the Research Center for Hydrogen Energy-based Society (ReHES), Tokyo Metropolitan University. The predecessor of this group is the Research Center for Gold Chemistry.
Gold was considered to be chemically inert until the end of 20th century. However, research spanning more than 30 years by emeritus Professor Haruta, (the first director of the Research Center for Gold Chemistry) has proved that gold has a rich catalytic function. When gold is dispersed and immobilized on base metal oxides as nanoparticles with diameters smaller than 10 nm, it can catalyze many chemical reactions at low temperatures. The catalytic performance can be tuned by selecting support materials and by controlling the size of gold. The predecessor Research Center for Gold Chemistry was established to pioneer new chemistry of gold based on catalysis, and was completed the role in November 2020.
We have been members of ReHES from December 2020 and are conducting research on "gold science and environmental chemistry" as well as "efficient use of hydrogen", both of which will be important technology in the near future. For gold nanoparticle catalysts, CO-PROX (preferential oxidation of CO under hydrogen-rich conditions), WGS (water-gas shift reaction), and selective synthesis of methanol by CO2 reduction have been reported. We are conducting research aiming at three-dimensional structural analysis of gold clusters, surface chemical properties, and simple chemistry that saves energy and resources, and does not produce by-products.
