The electrode comprises a conductive substrate, a conductive carbon additive, and a polymeric binder material. A material layer disposed on said conductive substrate, the material layer comprising an active material having a formula A2BX6, wherein A is an inorganic monovalent cation, B is a divalent metal cation, and X is a halide anion. The material enhances photo-assisted OER and offers potential STH benefits at the system level, making it suitable for renewable energy applications. An apparatus for electrolysis of water includes a reaction chamber, an electrode, a counter electrode, and a source configured to induce a water-splitting reaction to generate hydrogen and oxygen.en-USChemicalPatents Published[202421097808]123456789/11258
