Synthesis of mesoporous NiCo2O4 fibers and their electrocatalytic activity on direct oxidation of ethanol in alkaline media

Electrochemical Water Oxidation of NiCo2O4 and CoNi2S4 Nanospheres Supported on Ni Foam Substrate

“…The similar absorption with slight variations are reported by previous literatures . Tauc plot was drawn from UV data as shown in Figure B from the formula; αhυ=A(hυ‐Eg) n , where α, h, υ, and E g denoted the coefficient of absorption, Planck's constant, energy of incident photon and optical band gap respectively . It showed the intercept in X axis as optical band gap of the synthesized derivatives.…”

One – Step synthesis of nitrogen doped reduced graphene oxide with NiCo nanoparticles for ethanol oxidation in alkaline media

“…Co/N-RGO (40 mAcm -2 ) could be attributed to reduce of NiOOH and Co(IV) into Ni(OH) 2 and Co (III), respectively [25]. The catalyst long-term stability, because of poisoning of electrocatalyst due to the formation of oxidation intermediates such as CO, is more important in DAAFCs application.…”

High utilization efficiency of NiCo2O4 supported on porous graphene as noble metal-free catalysts for oxygen reduction reaction

“…The introduction of NiCo 2 O 4 into PGR sheet improves the electronic structure of PGR and provides a good ORR activity. The publications indicate that NiCo 2 O 4 possesses a much better electronic conductivity than single metal oxides [26,27,51]. The combination of PGR and NiCo 2 O 4 promotes the performance of NiCo 2 O 4 /PGR resulting from the inherited unique properties of both materials.…”

“…The transition metals such as cobalt or nickel are such a class of promising candidates for the FCs applications [14,18,20]. Their mixed valencies are beneficial for easy ion transportation [7,25,26]. Among them, spinel has particularly drawn a great deal of interest and considerable efforts have been devoted to its electrochemical applications in ORR [15,17,21,26e28].…”
