|a Constructing high catalytic activity heterojunctions to compensate for the shortcomings of single catalysts has promoted the development of semiconductor catalysts in photoelectrochemical (PEC) water splitting. In this case, the 2D/2D Bi2O2S/CdS composite was successfully constructed by an in situ surface epitaxial growth method. At 1.23 V vs RHE, the catalytic activity of Bi2O2S/CdS with a 2D/2D heterojunction is the highest, and the current density of the Bi2O2S/CdS photoanode is 3.46 mA/cm2. Compared with the Bi2O2S photoanode (0.59 mA/cm2), the performance has been improved by 5.86 times. In electrochemical impedance spectroscopy testing, the arc radius of 2D/2D Bi2O2S/CdS is smaller than that of Bi2O2S, indicating faster charge-transfer kinetics. The data show that the 2D/2D heterojunction with surface-surface contact successfully enhances the catalytic activity of Bi2O2S, greatly elevating the efficiency of charge separation and migration. This study provides a method to enhance the PEC activity in type-I heterojunction photoelectrodes, promoting the application of Bi2O2S-based materials in photoelectrochemistry
