Production of Hydrogen Peroxide by Photocatalytic Processes

Abstract

Hydrogen peroxide (H2O2) has received increasing attention because it is not only a mild and environmentally friendly oxidant for organic synthesis and environmental remediation but also a promising new liquid fuel. The production of H2O2 by photocatalysis is a sustainable process, since it uses water and oxygen as the source materials and solar light as the energy. Encouraging processes have been developed in the last decade for the photocatalytic production of H2O2. In this Review we summarize research progress in the development of processes for the photocatalytic production of H2O2. After a brief introduction emphasizing the superiorities of the photocatalytic generation of H2O2, the basic principles of establishing an efficient photocatalytic system for generating H2O2 are discussed, highlighting the advanced photocatalysts used. This Review is concluded by a brief summary and outlook for future advances in this emerging research field.

2D/2D heterostructured photocatalyst: Rational design for energy and environmental applications

“…In addition, the rational fundamental calculations and simulations based on density functional theory (DFT) should be also paid much more attention to, because they cannot only provide a better fundamental understanding of the formation as well photocatalytic mechanism but also guide the design of efficient 2D/2D photocatalysts. Finally, while the researchers explore novel 2D/2D photocatalysts to meet the requirements of highly efficient photocatalytic performance, one should also pay some attention to that there is plenty of space for developing the existing 2D/2D heterostructures for potential photocatalytic applications, e.g., hydrogen peroxide production [240].…”

PEO‐b‐PS Block Copolymer Templated Mesoporous Carbons: A Comparative Study of Nitrogen and Sulfur Doping in the Oxygen Reduction Reaction to Hydrogen Peroxide

“…[5,6] In past years the global production of H 2 O 2 exceeded 3million tons for av alue of 4.2 billion US$, and the global demandi sp rojected to rise at ar ate of almost4 -5 %/ year to reach 5.2 milliontons by 2020. [1] The commercially available H 2 O 2 mainly comes from the anthraquinone AO process, which was developedb yR iedl and Pfleiderer at BASF in 1939 and currently accounts for more than 95 %o ft he total H 2 O 2 production.T he AO process em-ploys hydrogen, anthraquinone and air (O 2 )a sr aw materials and Ni or Pd as catalyst, [1,7] and is carried out in organic solvents,w hich makes it inconvenient from the environmental point of view so that other green alternatives are currently under development including photocatalytic [7] and electrocatalytic [8][9][10] H 2 O 2 processes.…”

Efficient Photocatalytic Hydrogen Peroxide Generation Coupled with Selective Benzylamine Oxidation over Defective ZrS3 Nanobelts

“…3 Substantial efforts have been devoted to the development of effective photocatalysts for the H 2 O 2 generation from water and O 2 . 4 In this photocatalytic process, the sluggish oxidation of water induced by the photogenerated valence holes is a limiting factor for the production of H 2 O 2 . [5][6][7][8][9] Most previous reports focused on improving the half-reaction of O 2 reduction, e. g. by consuming holes with sacri cial agents, such as isopropyl alcohol, benzyl alcohol, and 2-PrOH.…”
