▎ 摘　　要

NOVELTY - The method involves sintering bamboo and pine shavings or scrap at 500 to 1500 degrees Celsius under oxygen atmosphere for 0.5 to 100 hour to obtain self-forming porous bamboo charcoal or charcoal. The porous bamboo charcoal or charcoal is immersed into 0.01 to 10 mol/L of transition metal ion solution for 1 to 1000 minutes. The bamboo charcoal or charcoal is immersed to strong oxidizing solution for heating at 500 to 1000 degrees Celsius for 0. 01 to 0. 5 hour, where the metal ion solution contains iron, cobalt and nickel. USE - Porous loading graphene transition metal nano composite catalyst preparation method. ADVANTAGE - The method enables preparing porous loading graphene transition metal nano composite catalyst with better air-permeable property to satisfy electrode reaction rapid conduction quality requirements. The method enables attaching transition metal nano-particle to an inner wall of a graphene channel firmly to realize water conductivity and forming micro-three phase reaction region to increases catalytic reaction. DESCRIPTION OF DRAWING(S) - The drawing shows a photographical view illustrating a porous loading graphene transition metal nano composite catalyst preparation method.
