A catalyst design for selective electrochemical reactions: direct production of hydrogen peroxide in advanced electrochemical oxidation

Abstract

Hydrogen peroxide production by enhanced electrocatalysts is an attractive alternative to the present commercial process.

Biomedicine Meets Fenton Chemistry

“…Thus, how to increase the amount of H 2 O 2 in the reaction motivates further exploration of a new strategy. In this section, we introduce some works that use semiconductors such as TiO 2 and C 3 N 4 to in situ produce H 2 O 2 to enhance the efficiency of Fenton/Fenton-like reactions. , …”

Selective Electrochemical Production of Hydrogen Peroxide from Reduction of Oxygen on Mesoporous Nitrogen Containing Carbon

“…[17] Continuous research is being carried out to produce H 2 O 2 in a facile manner so that activity and selectivity could be increased by development of an efficient catalyst for the same. [6,18,19] Until now, a range of electrocatalysts have been explored for electrochemical oxygen reduction including noble, nonnoble metal and metal free catalysts. [20,21] Noble metal-based catalysts are expensive and have low geographical distribution, and therefore the use of non-precious metal catalysts came into play.…”

Bacterial cellulose-regulated synthesis of metallic Ni catalysts for high-efficiency electrosynthesis of hydrogen peroxide

“…Recently, many studies have focused on developing highefficiency 2e − ORR electrocatalysts such as noble metal alloys [13][14][15], transition metal-based materials [16][17][18], and carbonaceous materials [19][20][21]. Transition metal-based materials show improved activity compared with their carbonaceous counterparts and are extremely cheaper compared with noble metal alloys; therefore, the former have gradually become the predominant electrocatalysts for H 2 O 2 electrosynthesis.…”
