An efficient and sustainable gas diffusible OER anode toward industrial alkaline water-splitting is fabricated by simply immersing Ni foam in ethanolic FeCl ₃ etchant, which produces a microporous Ni backbone decorated with nanocatalysts.

Zn-doping populates the catalytically active Ni ³⁺ -OOH sites, and subsequently prevents the detrimental competition between the UOR and OER. Consequently, Zn@Ni-MOF demonstrates an outstanding ultra-high UOR current density.

A scalable and economical drop-cast aided approach for the synthesis of a self-supportive thin-film of Cu–Fe–NH ₂ based MOF nanosheets as a highly efficient and durable electrocatalyst for water-splitting at high currents.

Hole doping leads to an efficient photo-induced interfacial charge transfer from MOFs to TiO ₂ and thereby the MOFs can harvest solar radiation to generate electricity.

A power conversion efficiency of 7.01% is achieved for TiO₂-based DSSCs using a chemically stable and mechanically robust MoS₂ counter electrode, from a simple, scalable and low-temperature wet-chemical process.
