METHOD OF PREPARING WATER-CRACKING CATALYST HAVING Mn4CaO4 AS CORE STRUCTURE AND APPLICATION THEREOF

摘要

The present invention provides a process for preparing a water splitting catalyst containing [Mn 4 CaO 4 ] core structure and use thereof. The present invention provides clusters containing [Mn 4 CaO 4 ] core structure by a chemical synthesis using inexpensive metal ions (Mn 2+ , Ca 2+ ions), simple carboxyl ligands and a permanganate, performed single crystal X-ray diffraction on their space structure, and characterized their physical and chemical properties with electron spectrum, electrochemical and electron paramagnetic resonance technologies and the like. These compounds can catalyze water splitting in the presence of oxidant to release oxygen and can also catalyze water splitting on the surface of an electrode to release electrons onto the surface of the electrode to form a current.
