Acesso em: 02 fev. 2015.0022-3697http://www.repositorio.ufop.br/handle/123456789/5035Here we describe a single chemical route to obtain highly dispersed nanometric Ni particles embedded in titania/carbon matrixes (amorphous and crystalline). The synthesis of these nanocomposites is based on a polymeric precursor method. The metallic Ni nanoparticles (1–15 nm) were obtained in a single process. We also present the results of photocatalytic experiments involving a series of nanocrystalline composites based on TiO2/carbon with embedded Ni nanoparticles as nanocatalysts for rhodamine 6G degradation in aqueous solution and investigate the effects of the structure and properties of the nanocomposites on their photocatalytic applications. The effect of the different annealing treatments on the formation of TiO2 nanophases (anatase and/or rutile), the size of Ni particles and the role of the residual carbon phase on the final solid are also described.en-USArtigo publicado em periodicoO periódico Journal of Physics and Chemistry of Solids concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
