Photocatalytic H2 production is one of the most promising approaches for sustainable energy. The literature presents a plethora carefully designed systems aimed at harnessing solar energy and converting it into chemical However, main drawback reported photocatalysts their stability. Thus, development cost-effective stable photocatalyst, suitable real-world applications remains challenge. An ideal photocatalyst must possess appropriate band-edge positions, an effective sacrificial agent, cocatalyst. Among various studied, TiO2 stands out due to its stability, abundance, non-toxicity. efficiency in visible spectrum limited by wide bandgap. Metal doping strategy enhance electron–hole separation improve light absorption efficiency, thereby boosting synthesis. Common metal cocatalysts used as dopants include platinum (Pt), gold (Au), copper (Cu), nickel (Ni), cobalt (Co), ruthenium (Ru), iron (Fe), silver (Ag), well bimetallic combinations such Ni-Fe, Ni-Cu, Nb-Ta, Ni-Pt. In all cases, doped exhibits higher performance compared undoped TiO2, metals provide additional reaction sites charge separation. use further optimizes hydrogen evolution reaction. Additionally, porphyrins, with strong efficient electron transfer properties, have demonstrated potential photocatalysis. Their incorporation expands photocatalyst’s range spectrum, enhancing efficiency. This review paper explores principles advancements metal- porphyrin-doped photocatalysts, highlighting production.
