Review of carbon-based nanocomposites as electrocatalyst for H2O2 production from oxygen

Hydrogen peroxide (H 2 O 2 ) is an environmentally friendly oxidant used in the chemical industry, sewage treatment, and waste gas purification. There are many ways to produce H 2 O 2 today. In recent years, electrocatalytic technology has received extensive attention from researchers because of its clean and efficient advantages. In the electrocatalytic reaction, the catalyst is the decisive factor affecting the reaction efficiency. Among all kinds of catalysts, carbon materials and their modified material catalysts have attracted broad attention because of their good electrocatalytic performance and low cost. Therefore, this review has discussed the carbon catalysts and summarized their development in recent years. Finally, in line with the trend of environmental protection, this review has briefly discussed and analyzed the application of H 2 O 2 in environmental protection.
