Abstract

Argilas pilarizadas formadas pela intercalação de óxidos de metais de transição, capazes de prevenir o colapso da estrutura, constituem materiais micro- e mesoporosos com diferentes atividades catalíticas e estabilidades. Argilas pilarizadas com cromo e com ferro foram utilizadas como catalisadores em reações de oxidação do cicloexano em fase gasosa. Os resultados indicam que os catalisadores são ativos e seletivos na produção de cicloexanona e cicloexanol. Entretanto, especial atenção deve ser dada à acidez superficial dos sólidos, responsável pela formação de cicloexeno no meio reacional, com conseqüente redução dos produtos de interesse.
