Abstract

2,3-Butanediol (2,3-BD) is a high-value chemical with wide applications in pharmaceuticals, polymers, and biofuels. Photocatalytic conversion of ethanol to 2,3-BD offers a promising route for sustainable chemical synthesis as it enhances the economic value of ethanol and reduces reliance on fossil fuels. In this study, we develop an efficient photocatalytic system for selective transformation of ethanol into 2,3-BD using Pt-modified Zn_0.75Cd_0.25S catalysts (Pt/Zn_0.75Cd_0.25S), demonstrating superior productivity and selectivity in neat ethanol compared to previous studies. The Pt nanoparticles on Zn_0.75Cd_0.25S significantly enhance the separation and transfer of charge carriers, thereby improving the photoredox catalytic activity. Moreover, the hydrogen bonding interactions between ethanol molecules and α-hydroxyethyl radical intermediates (•CH(OH)CH₃) play a pivotal role in facilitating the C–C coupling reaction, optimizing the selectivity toward 2,3-BD. This work offers valuable insights for the rational design of Pt-modified semiconductor photocatalysts, facilitating the selective transformation of ethanol into value-added chemicals and clean H₂ fuel.

pt修饰Zn0.75Cd0.25S催化剂上乙醇选择性光氧化还原C-C偶联

2,3-丁二醇（2,3- bd）是一种高价值的化学物质，在制药、聚合物和生物燃料等领域有着广泛的应用。乙醇光催化转化为2,3- bd为可持续化学合成提供了一条很有前途的途径，因为它提高了乙醇的经济价值，减少了对化石燃料的依赖。在本研究中，我们利用Pt修饰的Zn0.75Cd0.25S催化剂（Pt/Zn0.75Cd0.25S）开发了一种高效的光催化体系，用于选择性地将乙醇转化为2,3- bd，与以往的研究相比，在纯乙醇中表现出更高的生产率和选择性。Pt纳米粒子在Zn0.75Cd0.25S表面显著增强了载流子的分离和转移，从而提高了光氧化还原催化活性。此外，乙醇分子与α-羟乙基自由基中间体（•CH(OH)CH3）之间的氢键相互作用在促进C-C偶联反应中起关键作用，优化了对2,3- bd的选择性。这项工作为合理设计pt修饰的半导体光催化剂，促进乙醇选择性转化为增值化学品和清洁H2燃料提供了有价值的见解。
