Facile four-electrode electrolytic synthesis of defective PtPd/graphene with low Pt content for hydrogen evolution reaction and ethanol oxidation reaction

A comparative study of α-Ni(OH)2 and Ni nanoparticle supported ZIF-8@reduced graphene oxide-derived nitrogen doped carbon for electrocatalytic ethanol oxidation

“…36 However, the ZIF-8@rGO current density increases compared to the pristine ZIF-8 owing to the ability of electron transfer, high conductivity, and large surface area of the rGO which enable the reactants to reach the ZnO species in the enclosed structure of ZIF leading to the oxidation of ethanol. 93 Hence, the CV curves (Fig. 5a and S5a †) show a forward scan anodic peak at +0.32 V due to the reaction of Zn(II) ions with OH − to produce Zn(OH) 2 followed by a small current peak (2) at +0.49 V owing to the oxidation of the Zn(OH) 2 (Zn 2+ ) to ZnOOH (Zn 3+ ) according to eqn ( 5) and ( 6).…”
