The functionalization degree (amount of imidazolium groups per gram of PVG®) was successfully controlled by the concentration of the imidazolium-based alkoxysilane in the reaction media. The ion-exchange properties of the functional groups allowed an effective and homogeneous upload of AuCl4 - throughout the monolithic PVG® structure, with subsequent conversion to Au NPs by thermal treatment at 823 K, which also eliminated the organic groups chemically bonded to the surface. The amount of adsorbed AuCl4 - ions was shown to have influence on loading of the Au NPs while no size variation is observed, indicating that the porous environment of PVG® acts as a nanoreactor where the particles are formed in the confined spaceCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPAbertoUNIVERSIDADE ESTADUAL DE CAMPINASStrauss, Mathias, 1982-Damasceno, João Paulo Vita, 1990-Maroneze, Camila Marchetti, 1982-Costa, Luiz Pereira da, 1973-Sígoli, Fernando Aparecido, 1972-Gushikem, Yoshitaka, 1942-Mazali, Italo Odone, 1972-2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/20.500.12733/8051STRAUSS, Mathias et al.
