Síntese, caracterização e aplicação do MCM-41 e A1-MCM-41 na pirólise do resíduo atmosférico de petróleo
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2009-02-19)
In present work, mesoporous materials of the M41S family were synthesized, which were discovered in the early 90s by researchers from Mobil Oil Corporation, thus allowing new perspectives in the field of catalysis. One of ...
Cyclooctene epoxidation using Nb-MCM-41 and Ti-MCM-41 synthesized at room temperature
(Elsevier Science BvAmsterdamHolanda, 2004)
Cobalt nanoparticles on mesoporous MCM-41 and Al-MCM-41 by Supercritical CO2 Deposition
(Elsevier Science, 2012-01)
CoO and Co3O4 nanoparticles were uniformly dispersed inside mesoporous MCM-41 and Al-MCM-41 supports using supercritical CO2 reactive deposition. This method represents a one-pot reproducible procedure that allows the ...

Study of the effect of the base, the silica and the niobium sources on the [Nb]-MCM-41 synthesized at room temperature
(Elsevier Science BvAmsterdamHolanda, 2008)
Preparation of different basic Si-MCM-41 catalysts and application in the Knoevenagel and Claisen-Schmidt condensation reactions
(Academic Press Inc. Elsevier B.V., 2010-05-04)
In the present work, the basicity of three different Si-MCM-41 mesoporous materials, namely, (1) as-synthesized Si-MCM-41, (2) Si-MCM-41 modified by dispersing cesium oxide (Cs(2)O) and (3) Si-MCM-41 with anchored ...
Síntese da sílica MCM-41 usando um surfactante catiônico polimerizável e avaliação na transesterificação catalítica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Engenharia Química, 2014-02-20)
The masters work presented is result of a great effort provided by the group, which has worked with changes in the synthesis of CTA-MCM-41. The synthesis of the M41S family (composed of mesoporous silica MCM-41, MCM-48 and ...
