Título: | Exalted photocatalytic activity of tetragonal BiVO4 by Er 3+ doping through a luminescence cooperative mechanism |
Autor: | Obregón, Sergio CSIC ORCID; Lee S. W.; Colón, Gerardo CSIC ORCID | Fecha de publicación: | 2014 | Editor: | Royal Society of Chemistry (UK) | Citación: | Dalton Transactions 43: 311- 316 (2014) | Resumen: | Er-doped BiVO4 are synthesized by means of a surfactant free microwave assisted hydrothermal method having good photoactivities under sun-like excitation for the degradation of methylene blue. From the structural and morphological characterization, it has been stated that the presence of Er3+ induces a slight stabilization of the tetragonal phase, probably due to its incorporation in the BiVO4 lattice. The best photocatalytic performances were attained for the samples with Er3+ content higher than 3 at%. The occurrence of the Er3+ doped tetragonal BiVO4 clearly induces higher photocatalytic activities. The existence of a luminescence process has been related with the enhanced photoactivity observed. © 2014 The Royal Society of Chemistry. | URI: | http://hdl.handle.net/10261/98266 | DOI: | 10.1039/c3dt51923f | Identificadores: | doi: 10.1039/c3dt51923f issn: 1477-9226 |
