Facile one pot synthesis of nitrogen doped reduced graphene oxide supported Co3O4 nanoparticles as bifunctional catalysts for the reduction of 4-nitrophenol and NaBH4 hydrolysis

Oxygen deficient yolk–shell structured Co3O4 microspheres as an oxygen evolution reaction electrocatalyst for anion exchange membrane water electrolyzers

“…The A 1g symmetry of R-Co 3 O 4 -YS displayed a signicant negative shi, which demonstrated the creation of more oxygen vacancies. 30,31 All of these results veried that yolk-shell structured Co 3 O 4 microspheres aer NaBH 4 treatment could be achieved, featuring Co 3 O 4 nanosheets decorated on the surface of Co 3 O 4 -YS with enriched edge sites and oxygen vacancies, which would be benecial for the OER. 32 The catalytic activity of Co 3 O 4 -YS and R-Co 3 O 4 -YS for the OER was investigated by linear sweep voltammetry (LSV) in 1 M KOH (Fig.…”

Ag NPs decorated on the magnetic rod-like hydroxyapatite/MIL-101(Fe) nanocomposite as an efficient catalyst for the reduction of some nitroaromatic compounds and as an effective antimicrobial agent

“…Due to their porous structure and high surface area, HAP and MIL-101(Fe) provide more space for Ag NPs to perform the 4-nitrophenol reduction reaction and prevents the aggregation of Ag NPs, which reduces its catalytic performance. 35,36…”

MOF‐Templated Hierarchical Porous Hollow Core‐Shell Framework Cobalt Oxide for Enhancing Hydrogen Generation from Borohydride‐Based Hydrolysis

“…[11] For instance, Jacob et al developed nitrogen doped reduced graphene oxide supported Co 3 O 4 nanoparticles, which showed a maximum specific hydrogen generation rate of 2090.6 mL min À 1 g Co À 1 . [12] Dou and his co-colleagues prepared PdO-Co 3 O 4 composite and used it for H 2 generation from NaBH 4 hydrolysis, in which PdO-Co 3 O 4 catalyst has an exceptional turnover frequency (3325.6 mol H2 min À 1 mol Pd À 1 ) and low activation energy (43.2 kJ mol À 1 ). [13] Many other studies in the literature also aimed to develop noble metal doped cobalt oxide composites as reported elsewhere.…”
