Bifunctional catalysts have been considered to have vital importance in catalytic chemical process, but there is still some developing room for convenient materials with dual active sites. These catalysts have a notorious reputation for inhibiting mutual neutralization and controlling the distribution of active sites in order to perform their functions. We tailor a series of W-Zn-Al₂O₃ catalysts by modulating the doping density of metal species, which can boost the catalytic process of alcohols into corresponding carbonyl compounds in an additive-free-condition. Test results indicate that the proper content of zinc element can promote the overall activities, and subsequent adjustment of doping zinc can dramatically increase the electronic interaction and change the distribution of chemical active sites. Also, a plausible reaction mechanism was proposed to better understand the acid-base bifunctional catalytic process. Theoretical results confirm this system can provide certain references for similar reactants. Present reaction system is a green procedure and features a broad substrate scope, which reveals a sustainable method to process oxidative dehydrogenation reaction.

人们已经认为双功能催化剂在催化化学过程中至关重要，但是对于具有双活性位的便捷材料仍存在一些发展空间。这些催化剂因抑制相互中和和控制活性位点的分布以执行其功能而臭名昭著。我们量身定制了一系列W -Zn- Al ₂ O ₃通过调节金属物质的掺杂密度来制备催化剂，这可以在无添加剂的条件下促进醇转化为相应的羰基化合物的催化过程。测试结果表明，适当添加锌元素可以促进整体活性，随后对掺杂锌的调节可以显着增加电子相互作用并改变化学活性位点的分布。另外，提出了合理的反应机理以更好地理解酸碱双功能催化过程。理论结果证实该系统可以为类似的反应物提供一定的参考。目前的反应系统是绿色工艺，具有广泛的底物范围，这揭示了一种可持续的方法来处理氧化脱氢反应。
