Abstract

The invention relates to a material processing method, in particular to an electrode processing method applied to direct synthesis of hydrogen peroxide through oxygen electroreduction, and belongs to the field of hydrogen peroxide direct synthesis through electrochemistrical oxygen reduction. A processing method for etching a graphite felt electrode through ferrocene-glacial acetic acid solution steam is designed; the glacial acetic acid-ferrocene solution steam is injected under the high-temperature oxygen-free condition to etch the surface of the graphite felt electrode, the original smooth graphite felt microcosmic surface becomes rough and porous through the etching process, and the specific surface area can be simply and effectively increased; and meanwhile, surface changes cannot influence the graphite felt structure, and the mechanical property is kept well. In this way, the aims of improving the electrode activity and being free of influences on stability are achieved. The problem that an existing technology for direct synthesis of hydrogen peroxide through electro-catalysis oxygen reduction is low in electrode catalysis activity is solved.

Description

technical field

[0001] The invention belongs to the field of direct synthesis of hydrogen peroxide by electrochemical oxygen reduction, and relates to an electrode surface treatment method, in particular to a method for steam etching graphite felt with glacial acetic acid-ferrocene solution. Background technique

[0002] Hydrogen peroxide (H 2 o 2 ), also known as hydrogen peroxide, is an inorganic chemical raw material and fine chemical product, and is one of the 100 most important chemicals in the world. Hydrogen peroxide is oxidizing and is known as the "cleanest" chemical reagent because its decomposition product is water after use without any pollution. It is widely used in food, chemical, pharmaceutical and other fields. As a new "clean oxidant", it has attracted more and more attention from the industrial and scientific circles.

[0003] At present, the production methods of hydrogen peroxide include isopropanol method, anthraquinone method and electrolysis method,...
