Designing activated carbons from natural and synthetic raw materials for pollut...
P.A.M. Mourão; I.P.P. Cansado; P.J.M. Carrott; M.M.L. Ribeiro CarrottOver the last decades the literature has shown the possibility of producing activated carbons (AC) from a wide variety of raw materials, and to use them as one of the most environmentfriendly solutions for waste disposal [1]. Simultaneously, it has been shown that the adsorption of pollutants from different sources by activated carbons is one of the most efficient techniques for remediating or solving this kind...
Ordered mesoporous silica materials for protein adsorption
F. Sezões; M.M.L. Ribeiro Carrott; P.A.M. Mourão; P.A. Russo; P.J.M. CarrottLysozyme and BSA were used, as model proteins of considerably different dimensions, in order to evaluate the influence of the distinct pore structural characteristics of three types of ordered mesoporous silica materials (MCF, SBA-15 and MCM-41) on protein adsorption. Characterisation by X ray diffraction and nitrogen adsorption at 77K revealed the typical pore structural features of each type of material. The ...
Activated Carbons Prepared from Natural and Synthetic Raw Materials with Potent...
I.P.P. Cansado; P.A.M. Mourão; M.M.L. Ribeiro Carrott; P.J.M. CarrottA carbon molecular sieve for the purification of a gas mixtures containing O2, N2 and CO2, CH4 was produced from a waste granulated PET by means of a single carbonisation step at 973 K. Activated carbon materials presenting good adsorption capacity and some selectivity for O2/N2 and CO2/CH4 were prepared from granulated PET and cork oak with pore mouth narrowing using CVD from benzene. The diffusion coefficient...
