Photocatalysis offers a sustainable solution to two pressing global issues: greenhouse gas mitigation and clean energy generation. By harnessing light energy, photocatalytic processes enable water splitting for hydrogen production and CO 2 conversion into value‐added products. Among the materials explored for photocatalysis, nickel‐based photocatalysts have emerged as highly promising due to their low cost, abundance, stability, and efficiency. This review summarizes recent advancements in Ni‐based photocatalysts, highlighting their role in improving photocatalytic performance by enhancing light absorption, charge separation, and reducing charge recombination. Key challenges and future directions for optimizing these materials are also discussed, offering insights into their potential for advancing clean energy technologies.
