Abstract

The invention discloses a method for synthesizing molybdenum carbide nanometer materials, relating to a method for synthesizing carbides. The method aims to solve the problems of low catalytic efficiency and poor safety of the molybdenum carbide nanometer material obtained by the existing preparation method. Method: 1. Clean the carbon cloth; put the molybdenum trioxide powder into the quartz boat, spread the powder evenly, and place the carbon cloth on top of the molybdenum trioxide powder; 2. Place the carbon cloth and molybdenum trioxide Put the powdered quartz boat into the quartz tube of the chemical vapor deposition device, pass in the inert gas, reduce the flow rate, heat it, keep it warm, then turn off the heating system, increase the flow rate of the inert gas, cool naturally to room temperature, and take out the carbonized surface grown on the surface. Molybdenum nanostructured carbon cloth, that is complete. The molybdenum carbide nanostructure grown on the carbon cloth obtained in the present invention has a porous structure, uniformly covers the entire surface of the carbon cloth, has a large specific surface area, and has good catalytic hydrogen evolution performance. The invention is used for preparing molybdenum carbide nanometer material.

Description

technical field [0001] The present invention relates to a method for synthesizing carbide. Background technique [0002] In today's rapid development, energy issues have become the most concerned topic in daily research work. As a clean, efficient and sustainable energy source, the development technology of hydrogen energy has been widely concerned. One of the effective methods is electrochemical water splitting to produce hydrogen. Current studies have found that platinum-based noble metal catalysts have the highest hydrogen production efficiency, but due to their low content in nature and high price, their application in industry is limited. Nanostructured molybdenum carbide is considered to be the most promising alternative to noble metals as a catalyst for hydrogen evolution due to its abundant earth deposits, high catalytic activity, high stability, high electrical conductivity, and its acid-base versatility. And theoretical calculations show that the outer d orbital ...
