Electrocatalyst development has been a cornerstone for fuel cell applications but heavily hindered by several technical challenges, especially the insufficient activity and poor durability of electrocatalysts toward the sluggish kinetics of the oxygen reduction reaction. Here we propose our perspective on the exciting developments in unsupported platinum (Pt)-based nanocatalysts, with an emphasis on the multidimensional Pt architectures as an alternative to carbon-supported Pt electrocatalysts. After reviewing recent developments, we highlight the challenges and opportunities of unsupported Pt-based electrocatalysts, which may offer a broad materials library of noble metal structures for fuel cells and other sustainable energy technologies.

无载体的铂基氧还原反应电催化剂

电催化剂的开发一直是燃料电池应用的基石,但受到数项技术挑战的严重阻碍,尤其是电催化剂的活性不足和对氧还原反应反应迟钝的耐久性差。在这里,我们提出了关于无载体铂(Pt)纳米催化剂令人兴奋的发展的观点,重点是多维Pt结构作为碳载Pt电催化剂的替代物。在回顾了最近的发展之后,我们重点介绍了无支撑的Pt基电催化剂的挑战和机遇,这可能会为燃料电池和其他可持续能源技术提供广泛的贵金属结构材料库。
