Abstract

In-situ growth of W on the surface of a carbon cloth 18 o 49 The preparation method of the self-supporting electrode material, the analytical pure tungsten source is added to the mixed alcohol to obtain the solution A, and the analytical pure ethylenediamine and citric acid are added to the solution A to obtain the solution B; the solution B is poured into the polytetrafluoroethylene lined with high pressure Put the carbon cloth in the reaction kettle and put the carbon cloth into the polytetrafluoroethylene reaction kettle; put the sealed reaction kettle into the homogeneous hydrothermal reaction apparatus for hydrothermal reaction; wash the final reactant with absolute ethanol and centrifuge The washed material was dried to obtain in-situ growth of W on the surface of the carbon cloth 18 o 49 Self-supporting electrode material. Due to the high abundance and low price of carbon cloth, it has a large specific surface area, high electronic conductivity and ideal 3D open-pore structure. The present invention proposes to use carbon cloth as a supporting material, and adopts a solvothermal method to convert W 18 o 49 In situ growth on the support, the preparation of W with good electrocatalytic performance 18 o 49 / Carbon cloth nanomaterials.

Description

technical field

[0001] The invention belongs to the technical field of composite materials, and relates to a carbon cloth surface in-situ growth W 18 o 49 Preparation method of self-supporting electrode material. Background technique

[0002] Energy is an important basis for human survival and a driving force for national economic and social development. With the rapid development of the global economy and the rapid increase in population, non-renewable fossil fuels (oil, coal, natural gas, etc.) have been over-consumed and almost exhausted. And its combustion process will produce carbon dioxide, sulfur dioxide and nitrogen oxides and other gases. These gases can cause adverse consequences such as the greenhouse effect and acid rain, and their impact on the environment and climate is becoming more and more serious. Therefore, people are eager to find new ways to solve the current energy and environmental problems. Electrochemical electrolysis of water has been recognize...
