Photocatalysis provides a promising route to alleviate energy crises under mild reaction conditions. However, the low carrier separation efficiency greatly limits its industrial application. Herein, a fast interfacial channel to accelerate photocarrier transfer is rationally designed by selectively photodepositing two non-noble cocatalysts Ni and Mn on commercial TiO2 (P25). The as-obtained activity is enhanced nearly up to 60-fold higher than that of P25 for photocatalytic cyanation of olefins. Ni-0 and MnOx function as the photogenic electron and hole traps, respectively, suppressing carrier recombination. In addition, a compact interface with lower resistance and a shorter migration distance is formed between cocatalysts and TiO2, further enhancing the activity. This work may provide a cheap and facile method to design photocatalysts with high charge mobility and promising potential for large-scale application.
