Abstract
Here we report a facile and efficient method to prepare Pt spheres with hollow interior and nanosponge shell with high surface area. Such a unique Pt nanostructure can effectively improve the electrocatalytic performance of Pt catalysts by facilitating the access of electroactive species to the full-extent Pt surface.
摘要
在这里，我们报告了一种简便高效的方法来制备具有中空内部和纳米海绵壳的高表面积 Pt 球体。这种独特的 Pt 纳米结构可以通过促进电活性物质进入全 Pt 表面来有效提高 Pt 催化剂的电催化性能。
