Resumen
Las propiedades químicas/electroquímicas y ácidas de los óxidos binarios de Ti-Si y Nb-Si los hacen buenos candidatos como catalizadores en reacciones de deshidratación, fotocatálisis y oxidación (1), en adición, la interacción fuerte metal soporte (SMSI) y la posibilidad de obtener materiales con una alta área superficial (2), hace que estos sólidos, muestren un gran potencial como soportes catalíticos. Del procedimiento de síntesis depende la estructura del TiO, y del Nb,O sobre la superficie de la sílice (3) y por tanto sus propiedades como soporte o como catalizador, la presente revisión resume algunos aspectos de la síntesis y caracterización y da cuenta de sus principales aplicaciones en catálisis.
