A group of researchers in Brazil affiliated with the Center for Innovation in New Energies (CINE) have developed a groundbreaking method for purifying materials to enhance the efficiency of a film crucial in green hydrogen production. The material, mullite-type bismuth ferrite (Bi₂Fe₄O₉), acts as a photoelectrocatalyst in hydrogen production by oxidizing water or biomass derivatives using sunlight. The researchers at the State University of Campinas (UNICAMP) have successfully eliminated unwanted compounds from the material, known as secondary phases, through a purification process using glycerol and light. This purification method significantly boosts the performance of the photoelectrocatalysts, paving the way for cost-effective and sustainable material production for green hydrogen and water purification. The study, part of Bruno Leuzinger da Silva's doctoral research supervised by Professor Ana Flávia Nogueira, demonstrates the potential of using renewable and biodegradable compounds like glycerol to drive essential photoelectrochemical reactions. The research, supported by FAPESP, Shell, and other institutions, showcases a promising advancement in the field of sustainable energy production and environmental protection.
