Palladium (Pd) plays an important role in numerous catalytic reactions, such as methanol and ethanol oxidation, oxygen reduction, hydrogenation, coupling reactions, and carbon monoxide oxidation. Creating Pd-based nanoarchitectures with increased active surface sites, higher density of low-coordinated atoms, and maximized surface coverage for the reactants is important. To address the limitations of pure Pd, various Pd-based nanoarchitectures, including alloys, intermetallics, and supported Pd nanomaterials, have been fabricated by combining Pd with other elements with similar or higher catalytic activity for many catalytic reactions. Herein, recent advances in the preparation of Pd-based nanoarchitectures through solution-phase chemical reduction and electrochemical deposition methods are summarized. Finally, the trend and future outlook in the development of Pd nanocatalysts toward practical catalytic applications are discussed.
钯(Pd)在许多催化反应中起着重要作用,例如甲醇和乙醇氧化、氧还原、加氢、偶联反应和一氧化碳氧化。创建具有增加的活性表面位、更高密度的低配位原子和最大化反应物表面覆盖的基于钯的纳米结构非常重要。为了解决纯钯的局限性,通过将钯与在许多催化反应中具有相似或更高催化活性的其他元素结合,已经制备了各种基于钯的纳米结构,包括合金、金属间化合物和负载型钯纳米材料。在此,通过溶液相化学还原和电化学沉积方法制备基于钯的纳米结构的最新进展进行了总结。最后,讨论了钯纳米催化剂向实际催化应用发展的趋势和未来展望。
