Insights into the active surface species formed onTa2O5nanotubes in the catalytic oxidation of CO
(Royal Society of Chemistry, 2014-01)
Freestanding Ta2O5nanotubes were prepared by an anodizing method. As-anodized amorphousnanotubes were calcined at high temperature to obtain a crystalline phase. All materials were studied bymeans of BET analysis, XRD, ...
Catalytic abatement of CO over highly stable Pt supported on Ta2O5 nanotubes
(Elsevier Science, 2014-01)
The development of active and stable catalysts has emerged as an important strategy in the catalytic abatement of CO. This article reports the use of the novel Pt-based catalyst supported on crystalline Ta2O5 nanotubes ...
Influence of annealing temperature on corrosion resistance of tio2 nanotubes grown on ti–30ta alloy
(2020-08-01)
With little success, researchers has been searching for alloys with elements such as tantalum to improve the long-term life of implants. The Ti–30Ta alloy presents an elastic modulus E = 69 GPa that is close to that of ...
Optimization of anodization parameters in Ti-30Ta alloy
(2020-08-01)
The current metallic biomaterial still presents failures associated with the bulk alloy and the interface of material/human body. In previous studies, titanium alloy with tantalum showed the elastic modulus decrease in ...
