A Ni-doped mos2 electrode material supported by carbonized endive

Abstract

The invention provides a kind of carbonized chicory load Ni-doped MoS2 electrode material, first add the fluff of chicory cauliflower into the glacial acetic acid solution, dry after heating in a water bath; then put the dried fluff in a tube furnace, Heating to 500°C and calcining for 2 hours under atmosphere to obtain activated carbon microtubes; dissolve Na2MoO4 2H2O, CH4N2S, Ni(NO3)2 6H2O and PVP in deionized water, then add carbon microtubes to the above solution and stir evenly Disperse, transfer to a reactor, and react at 200°C for 24h to obtain Ni-doped MoS2 electrode material supported by carbonized chicory. The invention makes up for the disadvantages of slow mass transfer rate of electrolyte, poor conductivity of electrode materials, etc., and solves the problems of large overpotential of hydrogen evolution reaction and the like.

Description

technical field [0001] The invention relates to an electrode material, in particular to a Ni-doped MoS2 electrode material loaded with carbonized chicory. Background technique [0002] Hydrogen is a sustainable and clean fuel, which will play an important role in promoting the sustainable development of energy in human society. Although there is a high content of hydrogen on the earth, most of it exists in the form of water and cannot be used directly. Electrocatalytic water splitting for hydrogen production is considered to be a sustainable technology for producing high-purity hydrogen due to its abundant and readily available raw materials, high product purity, mild reaction conditions, and clean and pollution-free process. In actual production, most of the power loss is concentrated in the hydrogen evolution overpotential, so the key to improving the efficiency of alkaline electrolysis of water is to reduce the hydrogen evolution overpotential. In order to achieve effic...
