Esterification of organic acids with alcohols produces an industrially important class of
substances with a variety of applications. This work presents an impregnation route to …

Metal-Oxygen Clusters is the first book, providing an overview of the surface chemistry and
catalytic properties of heteropoly oxometalates. After a brief look at the early knowledge of …

Natural gas is acknowledged as the fuel for the 21st century. Natural gas is the cleanest
fossil fuel, and it is abundant. Furthermore, it is dispersed over a wide region, as opposite to …

The caesium, ammonium, and potassium salts of 12-tungstophosphoric acid (HPW) have
been prepared with different stoichiometries (1≤ x≤ 3), and their catalytic behavior …

Rigorous kinetic assessments, pyridine chemical titration and desorption, together with
density functional theory calculations establish the trends in the modulation of chemical …

Abstract Photoacoustic Fourier-Transform Infrared Spectroscopy (PAS-FTIR) has been used
to study the interaction of CH 3 OH with 12-tungstophosphoric acid (H 3 PW 12 O 40) and …

Physicochemical and catalytic properties of titania-supported 12-molybdophosphates have
been investigated. The samples were characterized by the S (BET) method, Fourier …

Nonporous heteropoly oxometalates are shown to be capable of absorbing polar molecules
into their bulk structures while retaining their properties as solids. The results from …

Differential heats of ammonia sorption onto and into heteropolyacids (HPA's) of tungsten
and molybdenum (HPW, HSiW, HPMo and HSiMo) were measured microcalorimetrically to …
