Abstract

Nickel-based catalysts, recognized for their cost-efficiency and availability, play a critical role in advancing hydrogen production technologies. This study evaluates their optimization in water electrolysis to improve eff iciency and system stability. Key findings highlight the enhancement of these catalysts with nickel-iron oxyhydroxide and nickel-molybdenum co-catalysts. Technological innovations, such as Perovskite Solar Cells integration for solar-to-hydrogen conversion, are explored. The use of nickel foam enhances electrode durability, offering valuable insights into designing sustainable and efficient hydrogen production systems.
