摘要：

Water splitting is an emerging domain in the sustainable energy system. In this study a half-sandwich [Ru(eta(6)-benzene)(hdm)]BF4 [Ru-hdm] complex (hdm=hydroxydi(pyridine-2-yl)methanolate) has been synthesized and characterized through various spectroscopic techniques. The complex [Ru-hdm] has been employed to investigate the activity towards electrochemical and chemical water oxidation. Efficient generation of O-2 through chemical and electrochemical water oxidation (98 % Faradaic efficiency) in deionized water was observed. The formation of insoluble particles of [Ru-VI=O] and [Ru-IV=O] species in the reaction mixture and a coating over the surface of the silicone rubber septum has been noticed. The kinetics of chemical water oxidation reveals the 1(st) order dependency on CAN and catalyst concentration.
