“…[6,11,[14][15][16] Graphene, as a two-dimensional material with a monolayer of carbon atoms, has been suggested to be a promising support material in the field of fuel cells because of its remarkable large surface area, high chemical stability and electrical conductivity. [17][18][19][20][21][22][23] Among graphene materials, reduced graphene oxide (rGO) can be prepared on a large scale and at low cost by chemical reduction of graphene oxide. Thus, it is an attractive carbon material for loading catalysts.…”

Pd and PdxNi nanoparticles have been supported on reduced graphene oxide (Pd/rGO and PdxNi/rGO) by using the microwave‐assisted heating method in glycol. The morphology, composition and electrochemical performance have been characterized by TEM, XRD, XPS and electrochemical methods. The XRD and XPS results show that there are no PdNi alloy particles formed in PdxNi/rGO and the composites exist mostly in the form of Pd0 and NiOOH species. The electrochemical results reveal that PdxNi/rGO synthesized from the feeding source of Pd and Ni with an atomic ratio of 4∶1 exhibits higher activity, better stability and smaller electron transfer resistance toward formic acid electro‐oxidation compared with commercial Pd/C, Pd/rGO and other PdxNi/rGO samples. The excellent electrocatalytic performance indicates that the addition of appropriate amount of Ni can greatly enhance the activity and stability of Pd catalysts for formic acid oxidation.

“…Tryptophan-functional graphene quantum dots (Try-GQD) were prepared by using the reported method. 25 Citric acid and tryptophan (1 : 1 molar ratio) were mixed and then heated at 180 °C for 3 h. Acetate buffer solution (0.1 M, pH 4.0) was prepared in the laboratory. Ultrapure water purified by the Milli-Q water system was used throughout the experiment.…”

Graphene has excellent mechanical properties with a low coefficient of friction and wear resistance and has a wide range of tribological applications. However, the stable dispersion of graphene in lubricating media is challenging. In this study, graphene is processed via covalent modification. A mild oxidation method selectively grafts carboxyl groups on the edge of the graphene sheet, before connecting tertiary alkyl primary amines through amide bonds. The alkyl chain allows graphene to be stably dispersed in hydrocarbon solvents.. FT-IR, XPS, Raman, XRD, SEM, etc. are used to characterize the covalently modified graphene (MG). Dispersion stability experiments showed that MG exhibited stable dispersion in 500N base oil and 15w-40 commercial lubricants, with stability for over 2 months. Tribological test results show that MG in 500N and 15w-40 significantly reduces the friction and wear of steel-steel friction pairs. The stable dispersion of MG in lubricating oil enables the formation of a stable chemical reaction film and graphene physical deposition film during the friction, protects the worn surface, and reduces direct contact, thereby significantly reducing friction and wear.
