Abstract
A new method to characterise the evolution of surface sites during metal-supported catalyst preparation has been developed, which exploits NMR relaxation times and their sensitivity to paramagnetic ions.
Highlights
A new method to characterise the evolution of surface sites during metal-supported catalyst preparation has been developed, which exploits NMR relaxation times and their sensitivity to paramagnetic ions
A large family of catalysts is that of metal and/or metal salts deposited on porous solid oxides, including silica, alumina, titania and other porous solids
A variety of methods have been developed over the years to prepare heterogeneous supported metal catalysts, which can be broadly classified as precipitation, deposition and impregnation methods.[5]
Summary
A new method to characterise the evolution of surface sites during metal-supported catalyst preparation has been developed, which exploits NMR relaxation times and their sensitivity to paramagnetic ions.
