Microwave Effects on Co–Pi Cocatalysts Deposited on α-Fe2O3 for Application to Photocatalytic Oxygen Evolution
Source abstract
Abstract
We analyze the effects of microwave applied in the process of photoelectrochemical deposition of cobalt-based cocatalysts, Co–Pi, onto well-orientated flat α-Fe 2 O 3 thin films, which were fabricated by pulsed laser deposition. As compared with conventional heating, microwave significantly affects the morphology, chemical composition, and photocatalytic activity of Co-Pi/α-Fe 2 O 3 composite. A significant enhancement in photocurrent related to photocatalytic water oxidation is achieved by the Co–Pi catalyst prepared under microwave irradiation. This, along with its interfacial electron-transfer properties, is studied by means of electrochemical impedance spectroscopy.
