Abstract
Inspired by nature, solar fuel production by splitting water into hydrogen and oxygen is a promising strategy to store solar energy into chemical bonds. An in-depth understanding of the water oxidation mechanism and the structure-function relationship of the catalyst is indispensable for developing advanced catalytic systems. Therefore, identifying a catalytic system that offers definite coordination environments for the formation of structurally defined transition metal active sites is essential for the reliable mechanistic studies of heterogeneous water oxidation.
This seminar will focus on the design of heterogeneous water oxidation catalysts with defined structures. The molecular metal sites grafted polymeric organic ligand/framework demonstrate promising water oxidation activities in neutral and alkaline electrolytes. Utilizing multiple kinetic research methods enables the analysis of the electrochemical behavior of different metal sites and the elucidation of the reaction mechanisms underlying their high activity.
