Hybrid palladium nanoparticles and nickel single atom catalysts for efficient electrocatalytic ethanol oxidation

Abstract: A Pd nanoparticle@Ni single-atomic catalyst (SAC) was developed for electrocatalytic ethanol oxidation. The Pd nanoparticles served as catalytic sites of ethanol, and the produced CO species adsorbed on Pd were electrochemically oxidized by Ni SAC.

“…Ethanol, with the advantages of large volume energy density (6.34 kWh L À 1 ), low toxicity, and easy accessibility from biomass, has also attracted increasing interests as promising fuel for fuel cells. [102,103] Therefore, DEFCs have been widely investigated. However, the lack of cost-effective electrocatalysts for EOR has severely hindered their widespread applications.…”

“…The attention on non-noble metal-based SACs has grown rapidly since 2018. Their applications have been extended to non-oxidative CH 4 conversion using Fe 1 /SiO 2 [61]; HER with Co 1 on N-doped graphene [59], graphitic carbon nitride [62], N-doped graphyne [63], and Ni 1 on α-SiX (X = N, P, As, Sb, Bi) [64]; ethylene benzene oxidation using Co 1 /CN [65]; electrocatalytic ethanol oxidation using a hybrid material of Pd nanoparticles and Ni 1 single atom [66]; oxidative desulphurization with Cr 1 /multiwalled carbon nanotubes [67]; CO oxidation using Ni 1 over FeO x [68], phosphorene nanosheet [69], Sc 1 and Fe 1 on honeycomb borophene/Al (111) heterostructure [70], and Ti 1 on MXene [71]; acetylene hydration using Zn 1 with S/N co-doped defective graphene supports [72]; the electrochemical CO 2 RR with Ni 1 on N-doped porous carbon [73], graphene nanosheets [74], carbon black [75] and other ZnN 4 -based SACs [76]; CO 2 hydrogenation with various non-noble metal-based SAC (Mn 1 , Fe 1 , Co 1 , Mo 1 ) supported on graphitic carbon nitride [77]; ORR has been carried out with Co 1 on defective N-doped carbon graphene [78], Fe 1 supported on N-doped porous carbon [79], hierarchically structured porous carbon [80], cellulose-derived nanocarbon [81] and phosphomolybdic acid cluster [82]; and the Oxygen Evolution Reaction (OER) has been carried out on Fe, Co and Ni-based SACs on N-doped graphene [83], N-doped biomass-derived porous carbon [84] as well as γ-graphyne monolayer [85]. Lastly, the production of H 2 O 2 was found to be effective via hydrogenation routes Ni-based SACs [86].…”

“…Among them, Ni, Co, Fe, Cu, etc. have been reported to provide abundant ⋅OH radicals [12–15] . It is worth mentioning that in order to promote CO ads removal in the lower potential range, more ⋅OH supply from the support matrix to Pt active sites would be a desirable way during MOR [16] .…”

[16] Inspired by the SACs, metal atomic dimers have also been reported very recently, in which two metal atoms are located near each other with the synergistic effects from the distinct structure.…”
