Abstract
- O objetivo deste Account e fornecer uma visao geral de nossas atividades atuais de pesquisa, as quais envolvem a sintese e modificacao de nanomateriais superparamagneticos para aplicacao na area de separacao magnetica e catalise. Primeiramente, uma introducao ao magnetismo e a separacao magnetica e feita. Em seguida, estrategias sinteticas que tem sido desenvolvidas para gerar nanoparticulas superparamagneticas revestidas esfericamente por silica e outros oxidos, com destaque a sistemas bem caracterizados e preparados por metodologias que geram amostras de elevada qualidade e que, a principio, podem ser produzidas em maior escala, sao discutidas. Uma serie de catalisadores magneticamente recuperaveis preparados em nosso grupo de pesquisa pela combinacao unica de suportes superparamagneticos e nanoparticulas metalicas e destacada. Este Account e concluido com observacoes pessoais e perspectivas neste campo de pesquisa. The aim of this Account is to provide an overview of our current research activities on the design and modification of superparamagnetic nanomaterials for application in the field of magnetic separation and catalysis. First, an introduction of magnetism and magnetic separation is done. Then, the synthetic strategies that have been developed for generating superparamagnetic nanoparticles spherically coated by silica and other oxides, with a focus on well characterized systems prepared by methods that generate samples of high quality and easy to scale-up, are discussed. A set of magnetically recoverable catalysts prepared in our research group by the unique combination of superparamagnetic supports and metal nanoparticles is highlighted. This Account is concluded with personal remarks and perspectives on this research field.
