Various materials are explored as OER catalysts, including:
Transition Metal Oxides: Materials like RuO2 and IrO2 are highly efficient but expensive. Perovskites: These materials offer tunable properties and good catalytic performance. Metal Phosphates: These materials are emerging as promising OER catalysts due to their stability and activity. Layered Double Hydroxides (LDHs): Known for their high surface area and tunability. Heterostructures: Combining different materials to enhance catalytic activity and stability.
