Abstract Photosynthesis in plants has inspired photochemical reactions organic chemistry. Synthetic chemists always seek cost‐effective, operationally simple, averting the use of toxic and difficult‐to‐remove metallic catalysts, atom economical, high product purity reactions. In last few decades, light as a catalyst increased exponentially literature exploded with examples, particularly by using expensive metal complexes, photosensitizers like dyes, hypervalent iodine, or inorganic semiconductors. this report, we have selected interesting examples performed without any photosensitizers. These inherent potential reactants to utilize energy initiate chemical Our main emphasis is highlight structural features that can absorb form an electron donor‐acceptor (EDA) complex during reaction reaction. Considering degree variability reactions, utmost care been taken present most accurate conditions. A short introductory section on will act anchor revolve around discussed explain underlying principle mechanism.

Hydrogen production via water splitting is a crucial strategy for addressing the global energy crisis and promoting sustainable solutions. This review systematically examines water-splitting mechanisms, with focus on photocatalytic electrochemical methods. It provides in-depth discussions charge transfer, reaction kinetics, key processes such as oxygen evolution (OER) hydrogen (HER). Various electrode synthesis techniques, including hydrothermal methods, chemical vapor deposition (CVD), pulsed laser (PLD), radio frequency sputtering (RF), are reviewed their advantages limitations. The role of carbon-based materials graphene, biochar, graphitic carbon nitride (g-C3N4) in photoelectrochemical (PEC) also highlighted. Their exceptional conductivity, tunable band structures, surface functionalities contribute to efficient separation enhanced light absorption. Further, advancements heterojunctions, doped systems, hybrid composites explored ability improve PEC performance by minimizing recombination, optimizing electronic increasing active sites reactions. Key challenges, material stability, cost, scalability, solar spectrum utilization, critically analyzed, along emerging strategies novel approaches development. By integrating materials, this comprehensive perspective production, bridging previously isolated research domains.
