    • Decomposição do NO sobre Cu suportado em zeólitas 

      Oliveira, Andréa Marins de; Pergher, Sibele Berenice Castellã; Moro, Celso Camilo; Baibich, Ione Maluf (2004) [Artigo de periódico]
      Direct decomposition of NO on copper supported on zeolite catalysts such as MCM-22 and Beta was compared with that on the thoroughly studied Cu-ZSM-5. The catalysts were prepared by ion-exchange in basic media. They were ...

    • Incorporação de dióxido de titânio em zeólitas para emprego em fotocatálise heterogênea 

      Merg, Jean C.; Rossett, Franciele; Penha, Fábio G.; Pergher, Sibele Berenice Castellã; Petkowicz, Diego Ivan; Santos, Joao Henrique Zimnoch dos (2010) [Artigo de periódico]
      This work proposes the study of heterogeneous photocatalysis using TiO2 impregnated in zeolites beta, ZSM-5, mordenite, NaXb, NaXp and NaY for the decomposition of methylene blue. The catalysts were characterized by XRD, ...

    • Um novo procedimento de síntese da zeólita A empregando argilas naturais 

      Rigo, Reus Tiago; Pergher, Sibele Berenice Castellã; Petkowicz, Diego Ivan; Santos, Joao Henrique Zimnoch dos (2009) [Artigo de periódico]
      This work proposes the synthesis of zeolite A by IZA standard proceedures starting from a natural clay. The clay was used in its natural form and after calcination at 900oC. The resulting materials were characterized by ...
