Abstract Photo‐electrochemical (PEC) water splitting systems using oxide‐based photoelectrodes are highly attractive for solar‐to‐chemical energy conversion. However, despite decades‐long efforts, it is still challenging to develop efficient and stable practical applications. Here, thin layers of covalent triazine frameworks (CTF‐BTh) containing a bithiophene moiety conformably deposited onto the surfaces Cu 2 O photocathode Mo‐doped BiVO 4 photoanode via electropolymerization construct new hybrid photoelectrodes, successfully addressing efficiency stability issues. The CTF‐BTh possesses suitable band structure form favorable edge alignment with each metal oxide, creating p–n junction staggered type‐II heterojunction , respectively. Thus, as‐fabricated exhibit substantially increased PEC performances. Meanwhile, film also serves as an effective corrosion‐resistant overlayer both inhibit photocorrosion enable long‐term operation 150 h only ≈10% loss in photocurrent densities. Furthermore, stand‐alone unbiased tandem device comprising CTF‐BTh‐coated exhibits 3.70% solar‐to‐hydrogen conversion efficiency. Even after continuous 120 h, can retain at 3.24%.
