Catalytic reduction of carbon dioxide to methanol is an attractive option to reduce
concentration of greenhouse gas and generation of renewable energy. Moreover, depletion …

Niobium chemistry is not widely known despite increasing interest in the application of
niobium compounds within many fields. Niobium materials are presently of great interest in …

This review article is devoted to the materials containing niobium, which have been
discovered or developed in the past few years and exhibit the potential application in …

Platinum deposited on supports (SiO2, γ-Al2O3, MgO, TiO2) covered with a transition metal
oxide monolayer (TiO2, V2O5, ZrO2) was used in hydrogenation of furfural to furfuryl …

The kinetics of CO2 reforming of methane was studied over Pt supported on Al2O3, ZrO2,
and x% ZrO2/Al2O3 (1≤ x≤ 20 wt%), and the catalysts were characterized using different …

We introduced oxygen vacancies into Nb 2 O 5 via thermal treatment at 700° C under
oxygen-deficient conditions for different lengths of time. Niobia-supported Pt catalysts were …

A novel metal/semiconductor nanocomposite with catalytic and photocatalytic functions has
been prepared. The new material consists of highly dispersed platinum (Pt) nanoparticles …

Abstract Pt/xNb 2 O 5/(100-x) Al 2 O 3 (x= 0, 5, 20, 100, wt.%) catalysts were tested on the
gas phase hydrodeoxygenation (HDO) of guaiacol (2-methoxyphenol, C 7 H 8 O 2), model …

In this work, ceria–niobia mixed oxides have been prepared by coprecipitation. The
structural, textural, and surface properties of these materials have been fully characterized …

Amorphous and crystalline niobium (V) and tantalum (V) oxides were treated with hydrogen
peroxide and studied by XRD, UV–vis, FTIR and ESR techniques to identify changes on …
