Abstract:
A facile and efficient strategy is described in this communication for preparing a molecular catalyst/semiconductor hybrid photoanode by immobilizing a cobalt cubane water oxidation catalyst onto a porous BiVO₄ electrode via electrochemical polymerization. With the introduction of Vpa as the anchoring linkage, the poly-1/Vpa/Al₂O₃/BiVO₄ photoanode exhibits high performance as well as stability for photoelectrochemical water oxidation.
