Abstract: With the most advances made so far in terms of photocatalyst design and preparation (inorganic photoredox nanoparticles), researchers of different expertise joined together to address sustainable energy conversion. Despite notable advancements in creating exceptionally active photocatalysts, the practical scalability of these innovations is hindered by issues such as ineffective utilization of solar energy and mass transport, recombination reactions, catalyst instability, and photo corrosion of the catalyst. In this roadmap review, we brief the fundamentals, latest progress, outstanding challenges, and novel design methodology for anticorrosive photocatalysts favorable to large‐scale hydrogen production. To enable the effective scaling of photocatalysis, beyond the inherent activity of photocatalysts, a range of additional factors are considered, with a primary focus on the design of photocatalytic systems. This review underlines the significance of well‐structured photocatalyst design and evaluation for achieving reproducibility and using dependable research methodology for conducting rigorous experiments. The recommendations are directed at reducing the uncertainty surrounding the optimism presented in published research, and we spotlight our recent research advancements. Importantly, the synergistic integration of design principles and research methodologies to enhance the anti‐corrosion properties of photocatalysts may pave the way for a practical technology to utilize solar energy for large‐scale hydrogen production efficiently.
