Dehydrogenation is a chemical reaction that produces value-added hydrogen-deficient chemical compounds with hydrogen molecules that can be ubiquitously used in chemical industries. Due to the bond-breaking process, dehydrogenation is usually endothermic, and it requires high energy input for achieving the sufficient reaction performance. Therefore, catalysts play an important role in lowering the activation barrier, and thereby enhancing the activity and reaction rate, and they also govern the product selectivity via control of the reaction pathway on the catalyst surface. The metal–support interaction (MSI) is a unique interaction occurring at the interface of metal nanoparticles and metal oxide supports in the solid-phase heterogeneous catalysts, which changes the electronic properties of the catalyst surface and hence the catalytic process. The control of MSI in the design of heterogeneous catalysts provided many opportunities for developing advanced catalysts having better catalytic performance. Herein, our comprehensive review explores the significant impact of MSI on catalyst design, emphasizing enhanced activity, superior product selectivity, and prolonged catalyst lifetime in dehydrogenation reactions. The discussion is structured around diverse perhydro molecules, highlighting the versatile applicability of MSI in tailoring catalysts for specific dehydrogenation processes.

金属负载非均相催化剂控制的催化脱氢制氢
脱氢是一种化学反应,可产生具有氢分子的增值缺氢化合物,可广泛用于化学工业。由于断键过程,脱氢通常是吸热的,并且需要高能量输入才能实现足够的反应性能。因此,催化剂在降低活化势垒、从而提高活性和反应速率方面发挥着重要作用,并且它们还通过控制催化剂表面的反应路径来控制产物选择性。金属-载体相互作用(MSI)是固相多相催化剂中金属纳米粒子和金属氧化物载体界面上发生的独特相互作用,它改变了催化剂表面的电子性质,从而改变了催化过程。 MSI在多相催化剂设计中的控制为开发具有更好催化性能的先进催化剂提供了许多机会。在此,我们的全面综述探讨了 MSI 对催化剂设计的重大影响,强调脱氢反应中增强的活性、卓越的产品选择性和延长的催化剂寿命。讨论围绕不同的全氢分子展开,强调了 MSI 在为特定脱氢过程定制催化剂方面的广泛适用性。
