Abstract
Hydrogen is considered a viable solution in the transition to cleaner and more sustainable energy sources. Its potential as a versatile and non-polluting fuel makes it a promising resource for reducing dependence on fossil fuels. Currently there are several processes to obtain hydrogen, however, some of these processes generate polluting gas emissions, being natural gas the main process to obtain hydrogen worldwide. An alternative method involves the use of photocatalytic semiconductor materials, which harness solar energy to catalyze the splitting of water molecules, producing oxygen and hydrogen. These materials work by absorbing sunlight, triggering a series of chemical reactions to break down water and release hydrogen. Although photocatalytic semiconductors have great potential, they still face application challenges. However, continuous advances in research and development are improving the efficiency and stability of these materials. This technology offers a sustainable and renewable pathway for hydrogen production, using solar energy as the primary source. The present research includes an overview of the methods for obtaining hydrogen, with emphasis on the photocatalysis process, which involves the implementation of photocatalytic semiconductor materials. It also provides a brief description of some investigations of photocatalytic materials for hydrogen production.
