外文摘要：Exploring efficient photocatalysts to facilitate water splitting into green hydrogen (H2) energy is of great significance nowadays. In this work, we successfully synthesized CdS nanoflowers coated by zero -dimen-sional MMoS4 (M = Ni, Co, Cu) cocatalysts using a mild two-pot solvothermal method. Notably, 2.5%-NiMoS4/CdS catalyst exhibits optimal photocatalytic H2 evolution from benzyl alcohol aqueous solution under visible-light irradiation, and its photocatalytic H2 activity (7269.5 mu molGreek ano teleiah-1Greek ano teleiag-1) is 10.1 times higher than that of pure CdS (716.6 mu molGreek ano teleiah-1Greek ano teleiag-1). Simultaneously, benzyl alcohol can be synergistically converted into benzaldehyde after dehydrogenation. Such excellent photocatalytic performance mainly benefits from the existence of an internal electric field (IEF), which is demonstrated by experimental analysis and density functional theory calculations. And the IEF greatly accelerates the separation of electron-hole pairs during the photocatalytic H2 evolution process. (c) 2022 Elsevier B.V. All rights reserved.
