Hybrid Molecular Photoanodes for Water Oxidation Based on Electropolymerized Cu Macrocyclic Complexes on BiVO4-WO3

The conversion of sunlight into chemical energy provides a sustainable alternative to fossil fuels that can significantly contribute to the mitigation of climate change. In this regard, water splitting with sunlight using semiconductors coupled with redox catalysts emerges as a potential pathway to...
