Pt and RhO cocatalysts are selectively deposited at inner and outer surface of ZnTiO N hollow nanospheres, respectively. The resulting photocatalytic systems exhibit promising activity for photocatalytic overall water splitting with stoichiometric H /O ratio under simulated solar insolation. Selective deposition of Pt and RhO cocatalysts at different surfaces not only mitigates back reactions of the products but also induces strong potential gradient within nanospheres that promotes efficient dissociation and fast migration of photocarriers to the surface.
Pt 和 RhO 共催化剂分别选择性地沉积在 ZnTiO3 空心纳米球的内、外表面。所得光催化体系在模拟太阳光照射下具有良好的全水分解性能，产氢和产氧的摩尔比为化学计量比。Pt 和 RhO 共催化剂在不同表面的选择性沉积不仅可以抑制产物的逆反应，而且可以在纳米球内诱导强电势梯度，促进光载流子的有效解离和快速迁移到表面。
