In the quest of renewable energy technologies, solar photoreforming emerges as one of the affordable yet challenging process for converting biomass into hydrogen, hydrocarbon fuels, and chemicals. This review highlights the state‐of‐the‐art photoreforming, elucidating its underlying mechanisms for the conversion of dissipated polymers into H2 and valuable chemicals. Biomass feedstocks such as carbohydrates, agricultural residues, glycopolymers, food wastes, and waste plastics are evaluated based on their chemical composition, energy content, and sustainability aspects, exploring the selection of appropriate bio‐renewable resources, considering their abundance, availability, and potential for hydrogen production. The impact of diverse process parameters on photoreforming efficiency is explored, encompassing factors like reaction temperature, pH, catalyst loading, reactor design, solvent effect, and light intensity across various sacrificial substrates. The discussion also considers their correlation with hydrogen production rate, selectivity, and energy efficiency. This review buckles on the design and synthesis of functional photocatalysts for biomass‐derived feedstock, highlighting their photocatalytic (PC) properties in biomass reforming processes and related feedstock into valuable chemicals and biofuel. The review also delves into potential pathways for future advancements including artificial intelligence (AI) and machine learning (ML), alongside addressing the challenges and insightful perspectives within this evolving field of future green energy.

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.This article is categorized under: Sustainable Energy > Solar Energy
