Niobium compounds and materials such as noibium pentoxide (Nb2O5), niobic acid
(Nb2O5· nH2O), niobium phosphate (NbOPO4), niobium layer compounds (K4Nb6O17 …

In South Korea, where there are no resources such as natural gas or crude oil, research on
alternative fuels has been actively conducted since the 1990s. The research on synthetic oil …

The book examines the design, application, and utilization of devices, techniques, and
technologies critical to research at the atomic, molecular, and macromolecular levels …

Four commercial aluminas and different cobalt loadings have been selected to better
understand the interactions between Co oxides and metallic cobalt with alumina surfaces …

Transition-metal oxides and noble metals are well-known selectivity and activity promoters
in cobalt-based Fischer–Tropsch catalysis. Niobia has been shown as an effective selectivity …

Cobalt catalysts were prepared by wet impregnation of three distinct supports: alumina,
niobia and 10 wt% niobia/alumina, prepared by wet impregnation of niobia precursor on …

Several series of supported cobalt catalysts were synthesized with different loadings and
supports. These catalysts were studied by in situ diffuse reflectance Fourier transformed …

Four iron-based catalysts supported on niobium oxide (Nb2O5) were prepared by
impregnation and characterized by TPR, FRX, DRX, and textural analysis. The catalysts …

Abstract Structure and catalytic performance of niobia-supported cobalt catalysts were
studied based on crystal phase, porosity and cobalt loading. Crystalline niobia as support …

The catalytic activity of Nb2O5 and Nb2O5/Al2O3-supported metal catalysts was evaluated
in the n-heptane conversion, CO hydrogenation and butadiene hydrogenation. After high …
