Intercalation-type Nb2O5, based on its inherent structural advantages in energy storage, shows excellent storage characteristics sodium-ion batteries (SIBs). The rapid pseudocapacitive Na-ion insertion/extraction dynamic mechanisms result outstanding rate performance. However, the low electronic conductivity hinders application and development SIBs. Though various modification projects can effe...

This study describes the application of Ag/Nb2O5 catalysts, suspension and spheres alginate immobilized for degradation 17α-Ethinylestradiol (EE2). The techniques used to characterize photocatalysts were as follows: X-ray diffraction (XRD), N2 adsorption–desorption analysis (BET), point charge zero (PZC), scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS). Different catalys...

The physical, electronic and reactivity properties of bulk and supported Group V metal oxides (V, Nb, Ta and Db) were compared at the molecular level. Dubnium is a very short-lived element, ∼60 s, whose properties have not been extensively studied, but can be predicted from knowledge of the other members of the Group V metal oxides. Bulk V2O5 possesses platelet morphology with the active surfac...

The study provides deep insight into the origin of photocatalytic deactivation Nb2O5 after modification with ceria. Of particular interest was to fully understand role ceria species in diminishing performance CeO2/Nb2O5 heterostructures. For this purpose, loaded on niobia surfaces by wet impregnation. as-prepared materials were characterized powder X-ray diffraction, nitrogen physisorption, UV–...
