Constructing van der Waals heterojunctions with excellent properties has attracted considerable attention in the field of photocatalytic water splitting. In this study, four patterns, coined A, B, C, and D Janus Ga2SSe/Bi2O3 (vdW) different stacking modes, were investigated using first-principles calculations. Their stability, electronic structure, optical analyzed detail. Among these, patterns A C demonstrate stable behavior operate as direct Z-scheme photocatalysts, exhibiting band gaps 1.83 eV 1.62 eV. addition, suitable edge positions make them effective for decomposition. The built-in electric across heterojunction interface effectively inhibits electron-hole recombination, thereby improving efficiency. absorption coefficients show that exhibit higher light intensity than Ga2SSe Bi2O3 monolayers, spanning from ultraviolet to visible range. corrected solar-to-hydrogen (STH) efficiencies are 13.60% 12.08%, respectively. application hydrostatic pressure biaxial tensile strain distinct effects on performance: preferentially enhances hydrogen evolution reaction (HER), while primarily improves oxygen (OER). Furthermore, exhibited enhanced UV-visible spectrum increasing pressure. Notably, a 1% results an improvement These hold great promise photocatalysts overall
