Abstract

The invention discloses a method for controllably loading metal platinum on the surface of a multi-wall carbon nanotube through an in-situ synthesis, which comprises the following steps of: (1) adding 10.0mg of multi-wall carbon nanotube and 10.0mg of platinum acetylacetone into 20.0mL of triethylene glycol, and performing ultrasonic treatment for 20 minutes by using ultrasonic equipment; and (2) and finally preparing a Pt / MWNTs nano composite material through anaerobic heating. The method has the advantages that: the preparation process is simple, convenient and efficient; and the prepared product can be used for cathode and anode catalysts for a direct methanol fuel cell, and also can be applied to cathode and anode catalysts for other fuel cells, and in the fields of gas reforming, pollutant treatment, organic matter cracking, organic matter synthesis and the like.

Description

technical field

[0001] The invention relates to a method for controllably loading metal platinum on the surface of multi-wall carbon nanotubes, in particular to a method for controllably loading metal platinum on the surface of multi-wall carbon nanotubes by an in-situ synthesis method. Background technique

[0002] A fuel cell is a device that converts the chemical energy of fuel and oxidant directly into electrical energy. Due to the advantages of high energy conversion density, diverse fuels, high reliability, low pollution, low noise, and easy maintenance, fuel cells are gradually becoming mainstream products in the energy field in the new century. Among them, the research on DMFCs and proton exchange membrane fuel cells (PEMFC) is more concerned. However, electrocatalyst has become one of the important factors restricting the commercial application of fuel cells. The reasons are as follows: (1) The electrocatalysts are usually noble metals such as Pt and their alloys...
