Olefin metathesis over tin-modified non-transition metal oxides
(Elsevier Science BvAmsterdamHolanda, 1999)
Er3+/Yb3+ co-activated silica-alumina monolithic xerogels
(Kluwer Academic Publ, 2003-01-01)
Monolithic silica xerogels doped with different concentrations of Er3+, Yb3+ and Al3+ were prepared by sol-gel route. Densification was achieved by thermal treatment in air at 950degreesC for 120 h with a heating rate of ...

Heteropolyacids with Keggin structure supported on silica-alumina
(Inderscience Enterprises, 2006-08-16)
The behaviour of molybdophosphoric acid, with Keggin structure, supported on different silica-alumina mixtures, obtained by sol-gel method, was studied. Different techniques were used to synthesise the supports. In one of ...
