Abstract

Photocatalytic water splitting using natural solar light is considered as a sustainable approach to generate H₂ and O₂. While H₂ has high market value, the by-product of water splitting, oxygen, is less valuable. To make H₂ produced by means of photocatalysis more economically competitive to that generated from methane, its generation is studied together with synthesis of organic compounds that have higher market value. This review summarizes and analyzes critically dehydrogenation reactions that were developed since 1980s. Photocatalytic dehydrogenation reactions are classified and the results are collected in the online database. Performance of homogeneous and heterogenous photocatalysts in dehydrogenation reactions, such as yield rates of organic products on analytical and preparative scales, and quantum efficiencies are compared. Current limitations of the existing methods and photocatalytic systems are identified and directions for the future developments are outlined.

期刊介绍： The journal covers a broad scope, encompassing new trends in catalysis for applications in energy production, environmental protection, and the preparation of materials, petroleum chemicals, and fine chemicals. It explores the scientific foundation for preparing and activating catalysts of commercial interest, emphasizing representative models.The focus includes spectroscopic methods for structural characterization, especially in situ techniques, as well as new theoretical methods with practical impact in catalysis and catalytic reactions.The journal delves into the relationship between homogeneous and heterogeneous catalysis and includes theoretical studies on the structure and reactivity of catalysts.Additionally, contributions on photocatalysis, biocatalysis, surface science, and catalysis-related chemical kinetics are welcomed.
