Abstract
Cocatalyst structure is crucial for optimizing the utilization of photogenerated charge carriers to enhance photocatalytic efficiency. Here, we reported an amorphous flower‐like hollow structure cocatalyst CoZnPx‐H with a large capacitance of 8.5 F/g about 19.7 times of that solid crystalline CoZnPx. The photocatalytic H2 production rate of CoZnPx‐H loaded on CdS achieves 54.0 mmol/g/h, which is 4 times greater than that of CoZnPx loaded on CdS. Interestingly, during the photocatalytic production, the simultaneous acetic acid rate from CoZnPx‐H/CdS arrives at 64.1 mmol/g/h, which is 2.2 times greater than that from CoZnPx/CdS. The excellent cocatalytic performance of CoZnPx‐H can be contributed to the strong capacitance, large surface area, excellent hydrophily brought about by its specific structure. The strong capacitance is beneficial for storing photo‐excited electrons, thus facilitating the efficient separation of photogenerated charges. The large surface area and excellent hydrophily provide abundant reactive sites and easy contact with reactants for proton reduction. As a result, the capacitance catalysis effect and surface redox kinetics improve, and the hydrogen and acetic acid simultaneously generate. This study proposes an effective strategy of modulating the cocatalyst structure to simultaneously obtain H2 and high‐value‐added chemicals.
