(Universidade Federal de Minas GeraisUFMG, 2011-08-25)
This work was divided into two main parts: (i) Synthesis, characterization and study of catalytic properties of niobium-doped goethites and (ii) Transformation of the goethites described in part (i) via chemical reduction ...
Nanoesferas de sílica - otimização das condições de síntese e estudo de propriedades.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2004-04-19)
The restriction in the application of molecular sieves in adsorption or catalytic process involving molecules with diameters higher than 0.8 nm, have lead to the study of solids possessing higher pore size. In that sense, ...
