KETJENBLACK CARBON SUPPORTED AMORPHOUS MANGANESE OXIDES NANOWIRES AS HIGHLY EFFICIENT ELECTROCATALYST FOR AN OXYGEN REDUCTION REACTION FOR A ZINC-AIR BATTERY AND PREPARATION THEREOF

摘要

PURPOSE: A manufacturing method of a composite catalyst is provided to manufacture a large amount of catalyst within short time at low temperature, and to provide amorphous manganese oxides nanowires with high oxygen reduction reactivity.;CONSTITUTION: A composite catalyst comprises a ketjenblack support; and manganese oxides supported by the support. A manufacturing method of the composite catalyst comprises a step of dispersing te ketjenblack support into glycol solvent, to preparing a suspension; a step of injecting manganese oxides precursor into the suspension, and conducting a reaction by adding basic material; and a step of obtaining a powder material by centrifugally separating the reaction solution; and a step of cleaning the powder material and drying the powder material in a vacuum state.;COPYRIGHT KIPO 2013
