A novel Silicon Nanowires/g-C3N4 core/shell arrays photoanode prepared by a mild and inexpensive metal-catalyzed electroless etching (MCEE) process followed by liquid atomic layer deposition (LALD), wiich is a facile and low-cost method. In comparison with FTO/g-C3N4 and Si NWs samples, the Si NWs/g-C3N4 samples showed significantly enhanced photocurrent which could be attributed to the SiNWs-based core/shell structure. A systematical PEC mechanism of the Si NWs/g-C3N4 was proposed is this manuscript.
