Depositing noble metals on specific facets of semiconductors can improve the separation of photoexcited hole-electron pairs during the photocatalytic reaction, resulting in enhanced photocatalytic performance. This work describes the selective deposition of noble metal nanoparticles (Au, Pt, Pd) on some specific facets of p-type Co3 O4 through a simple and facile photoassisted method. The deposition of Au nanoparticles (NPs) on {111} facets of Co3 O4 nanocrystals (NCs) can remarkably improve their photocatalytic activity towards water oxidation, which can be attributed to enhanced charge spatial separation. Moreover, the magnetically separated photocatalysts are good examples of new designed photocatalysts that can be recovered easily.

Co3 O4晶体上的金属（M = Au，Pt，Pd）纳米粒子的小平面选择性沉积：具有改善的催化性能的磁可分离光催化剂。

在半导体的特定面上沉积贵金属可以改善光催化反应过程中光激发的空穴-电子对的分离，从而提高光催化性能。这项工作描述了贵金属纳米颗粒（Au，Pt，Pd）通过简单且简便的光辅助方法选择性沉积在p型Co3 O4的某些特定表面上的方法。Au纳米颗粒（NPs）在Co3 O4纳米晶体（NCs）的{111}面上的沉积可以显着提高其对水氧化的光催化活性，这可以归因于增强的电荷空间分离。而且，磁性分离的光催化剂是可以容易地回收的新设计的光催化剂的良好实例。
