A facile co-precipitation synthesis of heterostructured ZrO₂/ZnO nanoparticles as efficient photocatalysts for wastewater treatment Quintana Puebla, Alberto Altube, Ainhoa García-Lecina, Eva Suriñach, Santiago Baró, M. D.. Sort Viñas, Jordi Pellicer Vilà, Eva Maria Guerrero, Miguel Gnm3 Altres ajuts: Basque Government ELKARTEK, FN KK-2015/0010 ZrO₂-decorated ZnO (ZrO₂/ZnO) nanoparticles (NPs) have been synthesized by a facile co-precipitation method in the presence of cetyltrimethylammonium bromide (CTAB) surfactant. The ZrO₂ amount in the NPs has been varied from 1.0, 2.0, 4.9, to 9.3% by weight. The resulting NPs are heterostructured and consist of a crystalline ZnO core (wurtzite phase) surrounded by an amorphous ZrO₂ layer. X-ray diffraction analyses support this observation. The NPs show a narrow size distribution and are slightly elongated. Compared to pure ZnO NPs, the hybrid ZrO₂/ZnO ones show enhanced photocatalytic activity toward the degradation of Rhodamine B under UV-Vis light. Such enhancement has been partly attributed to the increased amount of oxygen vacancies when ZrO₂ is incorporated into the NPs, as shown by X-ray photoelectron spectroscopy analyses. 2017 Article Ministerio de Economía y Competitividad MAT2014-57960-C3-2-R Ministerio de Economía y Competitividad MAT2014-57960-C3-1-R Ministerio de Economía y Competitividad RYC-2012-10839 Agència de Gestió d'Ajuts Universitaris i de Recerca 2014/SGR-1015 Journal of materials science ; Vol. 52, issue 24 (Dec. 2017), p. 13779-13789 open access Aquest material està protegit per drets d'autor i/o drets afins.
