The article discusses the current challenges in the energy sector, emphasizing the need for sustainable and environmentally friendly alternatives to fossil fuels. It highlights hydrogen as a promising solution due to its clean combustion, emitting only water vapor. However, the conventional method of obtaining hydrogen through fossil resources like steam reforming poses environmental concerns. To address this, the article proposes the use of hydrogen production via photocatalysis as a more sustainable approach. Photocatalysis involves activating a photocatalyst with light to generate reactive species that can facilitate the conversion of water or organic sacrificial agents from biomass into hydrogen. This process not only offers a renewable source of hydrogen but also utilizes solar energy, making it a greener option. TiO2 is identified as a prevalent photocatalyst due to its advantageous properties such as stability, affordability, and compatibility. The article concludes by noting the significant advancements in hydrogen production through photocatalysis and the ongoing efforts to enhance efficiency, scalability, and discover more effective photocatalysts to revolutionize energy production.
