Rare earth based photocatalysts for hydrogen peroxide production

Abstract

Hydrogen peroxide (H₂O₂) is a versatile compound with widespread applications in various industries. In addition, it has attracted interest as a potential energy carrier due to its high energy density and ability to release oxygen upon decomposition. The development of photocatalytic technology has enabled sustainable production of H₂O₂. Various structural materials, including organic molecules, polymers, and metal coordination compounds, have been synthesized for investigating photocatalytic H₂O₂ production. Rare earth materials, in particular, are of interest due to their adjustable porosity and controllable metal active sites, making them valuable for research in this field. These materials have excellent photoelectric properties, making them promise for the photocatalytic synthesis of H₂O₂. Despite limited reports on systematic reviews of photocatalytic H₂O₂ production using rare earth materials, this study introduces the principles and advancements in this area. It reviews different methods of photocatalytic synthesis of H₂O₂, focusing on rare earth elements. Through comprehensive analysis and systematic studies in the existing literature, a deeper understanding of enhanced photocatalytic performance has been achieved. This research not only contributes to advancing fundamental knowledge but also provides a solid foundation for practical applications.
