Computational chemistry to find a photocatalyst of Hydrogenjueves, 15 marzo 2018 Researchers from the IQTCUB Institute of the University of Barcelona have created computational models of titanium oxide nanoparticles. The advance will serve to find a catalyst that, with visible light, allows the division of water and generate hydrogen, one of the fuels of the future.Titanium oxide (TiO2) is a material with unique properties of photocatalysis and is being applied in many technological areas. One of the main properties it has is the ability to photocatalyze the breakdown of the water molecule to obtain a hydrogen molecule and an oxygen molecule. Hydrogen is the cleanest potential fuel that we could have, with the challenge of getting a clean procedure that allows us to stop using fossil fuels.
