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.

Wasserstoffperoxid (H2O2) steht verstärkt im Fokus der Forschung, da es nicht nur ein mildes und umweltschonendes Oxidationsmittel für die organische Synthese und Umweltsanierung ist, sondern auch ein aussichtsreicher flüssiger Brennstoff. Die Herstellung von H2O2 mittels Photokatalyse ist ein nachhaltiger Prozess, da dabei Wasser und Sauerstoff als Ausgangsmaterialien und Sonnenlicht als Energiequelle genutzt werden. In den letzten zehn Jahren wurden ermutigende Fortschritte in der Entwicklung von Prozessen zur photokatalytischen H2O2‐Produktion erzielt. In diesem Aufsatz bieten wir eine umfassende Zusammenfassung der Fortschritte auf dem Gebiet der photokatalytischen Produktion von H2O2. Nach einer kurzen Einleitung, in der die Vorteile der photokatalytischen H2O2‐Synthese herausgestellt werden, diskutieren wir die grundlegenden Prinzipien der Entwicklung effizienter photokatalytischer Systeme zur Produktion von H2O2 und stellen moderne Photokatalysatoren vor. Wir schließen den Aufsatz mit einer kurzen Zusammenfassung und einem Ausblick über die Fortschritte in diesem wachsenden Forschungsgebiet ab.

“…The mechanism of photocatalytic inactivation of microorganisms is reviewed by Byrne et al [20]. If TiO 2 on zeolite in green tuff and calcined ones is a photocatalyst, the hydrogen peroxide can be produced in the following equation as positive hole h + [15,21].…”

“…Photocatalysis describes the excitation of titanium dioxide nanoparticles (a wide-band gap semiconductor) by UV light to produce reactive oxygen species (ROS) that can destroy many organic molecules including fungi by the addition of inorganic salt potassium iodide [14]. Many kinds of photocatalytic productions of hydrogen peroxide on a semiconductor, such as TiO 2 , have been reported using water and oxygen with UV, however, hydrogen peroxide can be produced by using visible light [15,16]. The produced hydrogen peroxide can be decomposed by higher alkaline [17], UV light irradiation, and the Fenton reaction with the Fe 2+ ion.…”

Removal of Banana Tree Fungi Using Green Tuff Rock Powder Waste Containing Zeolite

et al. 2019

Hinai green tuff, which is found in Akita Prefecture, Japan, is used for the production of building materials, etc. About 60% of all stone is emitted as waste powder and therefore it is important to find ways for recycling it. In this work, the characteristics of green tuff powder have been investigated. The results of scanning electron microscope (SEM) and elemental map observations indicate that the green tuff contains TiO2 on zeolite. The green tuff can therefore be used as a natural catalyst for producing hydrogen peroxide with moisture and oxygen with light. The optimum calcined temperature of the green tuff powder is about 800 °C, producing the hydroxyl radical from hydrogen peroxide decomposition without ultraviolet light (UV) and decomposition of the superoxide anion. As the application of green tuff powder, Cavendish banana trees found in the Philippines infected by a new Panama disease were treated with powder suspension in order to remove the fungus (a type of Fusarium wilt) due to the photocatalyst characteristics of powder. The suspension, prepared by using the powder was sprayed on the infected banana trees for about one month. Photograph observation indicated that the so-called 800 °C suspension spray was more effective in growing the infected banana trees.
