Making fuels and chemicals from sunlight and abundant raw materials such as water and CO2 represents a major challenge to meet for a clean energy future. To achieve sunlight-driven water splitting, the integration of molecular H2-evolving catalysts into photoelectrochemical cells is a promising, yet challenging strategy. Our contribution to the field will be highlighted through different examples covering all aspects from catalyst design to the construction of functional water-splitting devices. Photoelectrochemical activity of dye-sensitized NiO photocathodes based on covalent dye – cobalt catalyst assemblies will be discussed in detail, together with some key insights into the factors currently affecting their performances, obtained from advanced spectroscopy and post-operando characterizations.
