Sobre IBD

A transformação fotocatalítica do sistema metano-dióxido de carbono foi investigada por métodos in situ no presente estudo. Catalisadores de ouro e ródio suportados por nanotubos de titanato (TNT) foram utilizados nos testes catalíticos. O nosso principal objetivo foi a análise do papel dos catalisadores nas diferentes partes do mecanismo de reação. Os catalisadores foram caracterizados por espectroscopia fotoelétrica de raios X (XPS), microscopia eletrónica de transmissão de alta resolução (HRTEM) e espectroscopia de refletância difusa UV-visível (DR-UV-VIS). Os testes fotocatalíticos foram realizados num reator de quartzo de fluxo contínuo equipado com detector de espectrometria de massa e fonte UV de arco de mercúrio. A espectroscopia de refletância difusa no infravermelho (DRIFTS) foi utilizada para analisar a superfície do catalisador durante a fotorreação. Testes pós-catalíticos também foram realizados nos catalisadores, incluindo métodos XPS, redução programada por temperatura (TPR) e espectroscopia Raman, a fim de acompanhar as mudanças nos materiais.
