Visible light catalysis H2O2 synthesis catalyst as well as preparation method and application thereof

Abstract

The invention discloses a visible light catalysis H2O2 synthesis catalyst as well as a preparation method and an application thereof. The visible light catalysis H2O2 synthesis catalyst is an organic polycomplexation matter formed by chromium, silver or indium ions with trithiocyanuric acid, is directly dispersed in a pure water system with alcohol as a sacrificial agent and can effectively reduce O2 to produce H2O2 under the induction action of visible lights, and each gram of catalyst can produce more than 0.20 mol of hydrogen peroxide. The preparation method of the visible light catalysis H2O2 synthesis catalyst disclosed by the invention is simple and easy to operate and raw materials are cheap, so that the preparation method disclosed by the invention is a clean, efficient and low-energy-consumption hydrogen peroxide production method applicable to industrialized popularization and application.

Description

technical field

[0001] The invention belongs to the field of photocatalysts, in particular to a visible light catalytic synthesis of H 2 o 2 Catalyst and its preparation method and application. Background technique

[0002] Hydrogen peroxide is an ideal green oxidant, and its production and use process has almost no pollution. It is called a "clean" chemical product and has a wide range of applications in chemical synthesis, bleaching, environmental protection, medicine and electronics. As the current global environmental pollution control requirements are being tightened and improved year by year, many types of inorganic oxidants such as H 2 SO 4 、HNO 3 and H 2 S, etc. have been eliminated from the market year by year, and the market demand for hydrogen peroxide is expanding day by day. At present, the most mature method for producing hydrogen peroxide is the anthraquinone method. Large domestic and foreign manufacturers basically use the anthraquinone method palladiu...
