The growing global energy demand and the urgent need to mitigate climate change have driven research toward clean and sustainable energy alternatives. Artificial photosynthesis emerges as a transformative solution by mimicking the natural process of photosynthesis to convert solar energy, water, and carbon dioxide into storable chemical fuels such as hydrogen and hydrocarbons. This paper explores the fundamental mechanisms of artificial photosynthesis, the development of photo catalysts, and the design of integrated systems like photo electron chemical (PEC) cells. Recent advances in materials, including perovskites, metal organic frameworks (MOFs), and carbon nitrides, have significantly improved light absorption and catalytic efficiency. Despite substantial progress, challenges remain in enhancing solar-to-fuel conversion efficiency, ensuring long-term catalyst stability, and scaling up for real-world applications. Socioeconomic impacts such as energy access in remote regions and the potential for decarbonizing the fuel sector are also addressed. The paper concludes with a perspective on interdisciplinary research directions and the role of artificial photosynthesis in achieving a sustainable and carbon-neutral energy future.
