Porous platinum, that has outstanding catalytic and electrical properties and superior resistant characteristics to corrosion, has been widely applied in chemical, petrochemical, pharmaceutical, electronic, and automotive industries. As the catalytic activity and selectivity depend on the size, shape and structure of nanomaterials, the strategies for controlling these factors of platinum nanomaterials to get excellent catalytic properties are discussed. Here, recent advances in the design and preparation of various porous platinum nanostructures are reviewed, including wet-chemical synthesis, electro-deposition, galvanic replacement reaction and de-alloying technology. The applications of various platinum nanostructures are also discussed, especially in fuel cells.
多孔铂具有出色的催化和电学性能以及卓越的抗腐蚀特性，已广泛应用于化学、石油化工、制药、电子和汽车行业。由于催化活性和选择性取决于纳米材料的尺寸、形状和结构，因此讨论了控制铂纳米材料这些因素以获得优异催化性能的策略。在此，综述了各种多孔铂纳米结构设计与制备的最新进展，包括湿化学合成、电沉积、置换反应和脱合金技术。还讨论了各种铂纳米结构的应用，特别是在燃料电池中的应用。
