What is the significance of benzyl alcohol in photocatalytic reactions

Label:chem

Topic
Benzyl alcohol (BA) is an organic compound that can be used as a substrate in photocatalytic reactions. Its oxidation can produce benzaldehyde, a valuable industrial raw material, while simultaneously generating hydrogen.

From: "Facile Synthesis of Ni3S2/ZnIn2S4 Photocatalysts for Benzyl Alcohol Splitting: A Pathway to Sustainable Hydrogen and Benzaldehyde", Catalysts 2025, 15(9), 830;
Answer
Benzyl alcohol is used in this study as a substrate for photocatalytic hydrogen production and benzaldehyde synthesis. The oxidation of benzyl alcohol requires less energy, enabling higher hydrogen yields even at lower light intensities. Additionally, benzaldehyde, a by-product of the photocatalytic reaction, is a valuable industrial raw material used in pharmaceuticals, pesticides, and fine chemicals.
