Method for preparing catalyst through solid-state electroreduction

Abstract

The invention provides a method for preparing a catalyst through solid-state electroreduction, and belongs to the field of catalyst synthesis. The method comprises the following steps: placing a sample in a sample tank, placing the sample tank in an insulating tube, respectively connecting positive and negative electrodes at two ends of the sample, contacting a thermocouple with one end of the sample, wherein the sample is an oxidation state metal or non-metal solid loaded on a conductive carrier, introducing a gas atmosphere into the insulating tube, starting a power supply device, electrifying the sample, and removing impurities from the electrified sample to obtain the catalyst. The method is simple and efficient, and the catalyst has catalytic activity.

Description

technical field

[0001] The invention belongs to the field of catalyst synthesis, and in particular relates to a method for preparing a catalyst by solid-state electroreduction. Background technique

[0002] Catalysts play a vital role in the field of energy catalysts, and different energy processes require different catalysts. For example, the fuel cell system that is expected to replace fossil energy currently requires the participation of platinum-based catalysts for the oxygen reduction reaction and the oxidation reaction of fuel (such as hydrogen). The core of the carbon dioxide electroreduction process, which is expected to solve carbon dioxide pollution and reuse, is also a catalyst. There are also important chemical processes such as nitrogen reduction, methanol oxidation, and petroleum cracking processes that require catalysts. Therefore, it is a problem that must be solved in the industry to be able to prepare uniform catalysts cheaply and in large quantities. At...
