Utilizing photocatalytic technology to efficiently convert biomass-derived compounds into value-added chemicals and release hydrogen gas can effectively address energy and environmental issues. For this purpose, we fabricated a series of NiMoS₄/Zn_0.6Cd_0.4S nanocomposites through a simple two-pot hydrothermal treatment. Dexterously, the photoexcited electrons and holes can be simultaneously utilized to participate in a photocatalytic redox reaction, effectively achieving the oxidation of furfuryl alcohol while cooperating with H₂ evolution. The hydrogen evolution rate of 10%-NiMoS₄/Zn_0.6Cd_0.4S nanocomposite in 1.50 vol % furfuryl alcohol aqueous solution is as high as 289.5 μmol·h^–1, which is approximately 2895 and 41 times higher than that of pure NiMoS₄ and Zn_0.6Cd_0.4S, respectively. Meanwhile, after 13 cycles of photocatalytic reaction, the conversion efficiency and selectivity of converting furfuryl alcohol to furfural are 68.5% and 94.0%, respectively. This photocatalyst also shows high photocurrent, low impedance, and efficient photogenerated carrier separation and transport properties, which can be attributed to the establishment of an ohmic junction between NiMoS₄ and Zn_0.6Cd_0.4S. It is anticipated that this work can provide inspiration for the effective conversion of biomass-derived platform chemicals into high-value chemicals through visible-light-driven photocatalytic technology.

NiMoS4/Zn0.6Cd0.4S 纳米复合材料促进光催化产氢与糠醇选择性氧化成糠醛

利用光催化技术有效地将生物质衍生的化合物转化为增值化学品并释放氢气可以有效解决能源和环境问题。为此，我们通过简单的两锅水热处理制备了一系列NiMoS ₄ /Zn _0.6 Cd _0.4 S纳米复合材料。巧妙地，可以同时利用光生电子和空穴参与光催化氧化还原反应，在配合H ₂析出的同时，有效实现糠醇的氧化。 10%-NiMoS ₄ /Zn _0.6 Cd _0.4 S纳米复合材料在1.50 vol %糠醇水溶液中的析氢速率高达289.5 μmol·h ^–1，分别是纯NiMoS ₄的2895倍和41倍。分别为Zn _0.6 Cd _0.4 S。同时，经过13轮光催化反应，糠醇转化为糠醛的转化效率和选择性分别为68.5%和94.0%。该光催化剂还表现出高光电流、低阻抗和高效的光生载流子分离和传输特性，这可归因于NiMoS ₄和Zn _0.6 Cd _0.4 S之间欧姆结的建立。预计这项工作可以为以下方面提供启发：通过可见光驱动的光催化技术，将生物质衍生的平台化学品有效转化为高价值化学品。
