“…In the former, an additional cathodic wave was observed at −1000 mV with a shoulder around −650 mV vs. Ag/AgCl (cathodic scan). These waves at negative potential are detected with values similar to that of TiO 2 (P-25) [23]. This behavior is in agreement with TiO 2 in zeotype matrices [32].…”

“…Conforme estudos realizados anteriormente por nosso grupo de trabalho, 12 ficou claramente demonstrado a partir da caracterização por sonda eletrônica (SEM-EDX) e espectroscopia fotoeletrônica de raios-X (XPS) que a imobilização de Ti capaz de gerar uma distribuição uniforme no suporte zeolítico é aquela correspondente a 10% de Ti/zeó-lita. Valores inferiores produzem sistemas menos ativos e mais passíveis de envenenamento, enquanto valores superiores acarretam a formação de agregados de TiO 2 sem interação com o suporte e inativos para as reações de fotodecomposição.…”

“…The structural bands at 450-900 cm −1 are attributed to the stretching vibrations of T-O, T-O-T, and O-T-O bonds in tetrahedral SiO4 and AlO4 units (T = Si or Al atoms). At the same time, no evident bands were observed in the region of 950-960 cm −1 , commonly assigned to the antisymmetric stretching vibration of the Ti-O-Si bond [42,46]. As it is suggested that no strong chemical interaction takes place between the TiO2 species and the zeolite, TiO2 is likely dispersed on the surface of the zeolite or partially encapsulated within the zeolite cavities [47,48].…”
