A New Method for Preparing Activated Carbon Catalyzing Oxygen Reduction Reaction (ORR) from Fast—growing Paper Mulberry

摘要

The invention discloses a new method for preparing catalytic oxygen reduction reaction (ORR) activated carbon from fast-growing paper mulberry. In the invention, catalytic 5 activated carbon (NAC) is prepared through low-temperature hydrothermal reaction and steam activation reaction with paper mulberry branches as the raw materials. The detailed steps are as follows: the paper mulberry branches are peeled, dried, crushed, dosed into a stainless steel reactor with PTFE lining, added with water and acid solution, stirred uniformly, sealed, and put in an oven for reaction. The reaction 10 products are naturally cooled down to the room temperature, filtered, washed with hot water and dried; the dried sample is roasted at high temperature in nitrogen atmosphere, activated with steam, washed and ground to obtain NAC. The synthetic method of the invention is simple, environment-friendly and easy to realize, and the catalyst prepared can be used to catalyze ORR.
