Synthesis and characterization of glycol ether and oxime modified precursors of niobium(V) for soft transformation to niobia

Nanosheet-structured vanadium pentoxide thin film as a carbon- and binder-free cathode for lithium-ion battery applications

“…In the process of reaction, benzyl alcohol as a reducing a g e n t a n d i s o p r o p y l a l c o h o l a s t h e s o l v e n t , [VO(OH) x (OC 3 H 7 ) y-x ] n (3≥y≥2, y≥x≥0) (for convenience, denoted as VO x ) oligomers are formed during the complicated chemical reactions [20]. It is worth noting that in such vanadium alkoxides form, vanadium stayed in an intermediate state that we cannot simply regard it as a combination of V5+ and V4+.…”

Self-assembled three-dimensional hierarchical porous V2O5/graphene hybrid aerogels for supercapacitors with high energy density and long cycle life

“…The as-prepared light yellow sol was composed of vanadium oxide (VO x ) oligomers; Scheme S1 † shows the possible chemical reaction pathway for producing the V 2 O 5 sol. [21][22][23] Graphene oxide (GO) aqueous solution was then added to the V 2 O 5 sol under vigorous stirring to induce hydrolysis and in situ recombination of the GO sheets and VO x oligomers. A dark red VO x /GO hybrid gel was obtained aer about 5 min because of the rapid formation of vanadium intermediate phases and growth of nanobers.…”
