Catalytic Effect of Nb2O5 in MgH2-Nb2O5 Ball-Milled Composites [PDF]

open access: yesCatalysts, 2012
We report a study on the desorption properties, crystallography and chemical state of MgH2 and 1 mol% Nb2O5 ball-milled composites. Desorption temperatures of the composites decreased with increase of ball-milling time. Size of MgH2 crystallites decreased during ball-milling.

Electrochromic Properties of Sol-gel Coating of Nb2O5 and Nb2O5:Li+ [PDF]

open access: yesMaterials Research, 2002
Thin solid films of Nb2O5 and Nb2O5:Li+ were prepared by the sol-gel process using the sonocatalytic method. The films reported here were prepared from a NbCl5 as precursor and butanol as solvent. Through the addition of lithium salt LiCF3SO3 to the precursor solution, films with different electrochemical performance were obtained.
