Rare earth-based alloy nanostructures show great potential as materials in the hydrogen evolution reaction (HER), and they have a relatively negative enthalpy of formation compared to traditional transition metal alloys, which resist dissolution alloys reaction. In addition, liner relationship can be observed d-band filling electrochemical activity. Therefore, rare nanostructure contains advantages transmission catalysts performs better selectivity stability. However, reduction potentials earth (RE) group are relevantly low, typically less than −1.9 V, synthesis methods RE very important. this Perspective, we generalize preparation method their applications related Through recent research on reaction, future development direction is pointed out.

By providing dual active sites to synergistically accelerate H2 O dissociation and H+ reduction, ordered intermetallic alloys usually show extraordinary performance for pH-universal hydrogen evolution reaction (HER). Herein, activated N-doped mesoporous carbon spheres supported Pt3 Fe (Pt3 Fe/NMCS-A), as a highly-efficient electrocatalyst HER, are reported. The Fe/NMCS-A exhibits low overpotentials (η10 ) of 13, 29, 48 mV deliver 10 mA cm-2 in 0.5 m SO4 , 1.0 KOH, phosphate buffered solution (PBS), respectively, well robust stability maintain the overall catalytic performances. Theoretical studies reveal that strong Pt 5d-Fe 3d orbital electronic interactions negatively shift d-band center (εd 5d orbital, resulting reduced H* adsorption energy enhanced acidic HER activity. With acting co-adsorption *OH intermediates, barrier is required dissociate afford which greatly promotes formation alkaline neutral conditions. synthetic strategy further extended synthesis Co Ni with excellent activity electrolytes, demonstrating great potential these Pt-based practical applications.

Abstract A crucial issue restricting the application of direct alcohol fuel cells (DAFCs) is low activity Pt‐based electrocatalysts for oxidation reaction caused by intermediate (CO*) poisoning. Herein, a new strategy demonstrated making class sub‐monolayer YO x /MoO ‐surface co‐decorated ultrathin platinum nanowires (YO –Pt NWs) to effectively eliminate CO poisoning enhancing methanol electrocatalysis. By adjusting amounts and MoO decorated on surface Pt NWs, optimized 22% NWs achieve high specific 3.35 mA cm −2 mass 2.10 mg −1 , as well enhanced stability. In situ Fourier transform infrared (FTIR) spectroscopy stripping studies confirm contribution anti‐CO ability NWs. Density functional theory (DFT) calculations further reveal that Y Mo atoms with states allow COOH* bind through both carbon oxygen atoms, which can lower free energy barriers CO* into COOH*. The optimal also show superior activities toward electro‐oxidation ethanol, ethylene glycol, glycerol.

Layered double-hydroxide (LDH) has been considered an important class of electrocatalysts for the oxygen evolution reaction (OER), but adsorption-desorption behaviors intermediates on its surface still remain unsatisfactory. Apart from transition-metal doping to solve this electrocatalytic problem LDH, rare-earth (RE) species have sprung up as emerging dopants owing their unique 4f valence-electronic configurations. Herein, Er is chosen a RE model improve OER activity LDH via constructing nickel foam supported Er-doped NiFe-LDH catalyst (Er-NiFe-LDH@NF). The optimal Er-NiFe-LDH@NF exhibits low overpotential (191 mV at 10 mA cm-2 ), high turnover frequency (0.588 s-1 and activation energy (36.03 kJ mol-1 which are superior Er-free sample. Electrochemical in situ Raman spectra reveal facilitated transition Ni-OH into Ni-OOH promoted kinetics through effect.
