Resumen

The nanostructures were obtained by the laser ablation technique in liquid medium, depending on the preparation conditions, Bi or Bi₂O₃ nanoparticles, or Bi₂O₃ nanosheets are obtained. Thin films were deposited by CVD obtaining the TiO₂ anatase phase. Catalyst activation was carried out using a solar simulator irradiating at 31 mW/cm². The degree of degradation of malachite green was determined by measuring the decrease in the intensity of its characteristic absorption band at 619 nm. In general terms, the results show that thin films with Bi based nanostructures supported exhibit a better photocatalytic activity than the TiO₂ sample.
