“…The electrochemical activity and stability of the prepared Pd−Cu/RGO composites for ethanol electro‐oxidation were studied in alkaline media using chronoamperometry, based on which not only high catalytic activity but also excellent stability was observed, as represented in Figure . It was attributed to the bimetallic structure of the prepared composites, consisting of a small Pd−Cu core surrounded via a thin Pd‐rich shell, enhancing the catalytic activity of the prepared Pd−Cu/RGO hybrids …”

[96] In another research, Zhang et al synthesized a reduced graphene oxide-supported Pd-on-Cu nanoparticles hybrid (Pd-on-Cu/RGO) in ethylene glycol systems, employing cetyltrimethylammonium bromide (CTAB) as a structuredirecting agent, through a one-pot solvothermal approach, as depicted in Figures 37 and 38. Control experiments, through which composites were fabricated without CTAB, labelled PdCu/RGO, or GO, labelled PdCu, indicated the key role of CTAB and GO to the final morphology.…”

This review gives an overview of the electrochemical investigations about the properties of various types of graphene composites in the ethanol oxidation. Various routes to provide appropriate graphene‐based materials required electrochemical techniques for investigation of different types of the materials as well as their performance and efficacy in ethanol oxidation are discussed in detail. Furthermore, it is demonstrated that the incorporation of suitable materials, e. g. noble metals (graphene‐supported binary and ternary metal nanoparticles), metal oxides, conductive polymer, etc, with graphene results in excellent electrocatalytic activity, superb durability and selectivity in ethanol oxidation. Immobilization of electrocatalytically active NPs on graphene supports using physical approaches is considered as an effective route to prepare direct ethanol fuel cell (DEFC) anode catalysts.

“…The graphene materials have been emerging in the electrocatalysis and electroanalysis as the potent surface modifying agents for the working electrodes, where the presence of graphenated materials selectively increased the rate of electron transfer and sensitivity of determination of the analyte [16][17][18][19][20][21][22][23][24][25]. However, the aqueous electrochemistry of the actinides on graphenated materials is yet unexplored.…”

CO2 electrocatalysis as a hydrocarbon is a promising means of achieving economical CO2‐mediated hydrogen energy cycling. Hydrocarbons are renewable hydrogen storage materials. The development of reliable metal alloy electrocatalysts is an urgent but challenging task associated with such systems, although there is still a lack of precise reaction mechanism design. In this study, the performance of Pd10Ag5 alloy nanoparticles (NPs) and Pd10Sn5 alloy nanoparticles (NPs) on the electrocatalytic reaction of CO2 was compare. The kinetic and density functional theory (DFT) calculations show that the selectivity of the Pd‐based bimetallic catalyst to the C2 product is greater than that of C1, and the stability of Pd10Ag5 is better and less affected by the reaction environment. However, the catalytic performance of the Pd10Sn5 electrocatalyst in the liquid phase is the best. The insight obtained from the calculations is used to develop criteria for identifying new and improved catalysts for electrochemical CO2 reduction.
