Facet engineering of photocatalytic particles has been proven to be effective in enhancing charge separation efficiency, particularly via interfacet built-in electric field, thus improving performance. However, whether also occurs within a facet remains unclear. Here, we found that reduction cocatalysts and oxidation are distributed on single cubic SrTiO3 crystal photodeposition. Rh predominantly deposited the central region, whereas CoOOH preferentially near edges, indicating photogenerated electrons accumulated at center holes edges. This intrafacet leads 2.7-fold improvement overall water splitting efficiency compared with randomly cocatalysts. These findings advance understanding facet-based offer new perspectives for rational design high-performance photocatalysts beyond engineering.
