Coupling cathodic hydrogen evolution reaction (HER) and anodic electrochemical oxidation of organic small molecules in a co-electrolysis system could simultaneously realize high value chemicals generation and energy-saving hydrogen production, which...

Engineering metallenes for boosting electrocatalytic biomass-oxidation-assisted hydrogen evolution reaction

“…48,49 Recently, Wang and coworkers synthesized a S and P dual-doped Pd metallene (PdSP metallene). 34 In such a PdSP metallene system, the co-incorporation of S and P atoms endows the resultant PdSP metallene with abundant active sites and significantly increases the electrochemically active area. Moreover, the electronic interaction between Pd and nonmetals can also optimize the electronic structure of active sites and modify the intermediates’ affinity toward the active sites.…”

“…Moreover, some effective strategies are also proposed to improve their electrocatalytic performance, including alloying, atomic doping, nonmetal doping, strain engineering, defect engineering, surface functionalization, and heterostructure engineering. 29–34…”

“…Moreover, some effective strategies are also proposed to improve their electrocatalytic performance, including alloying, atomic doping, nonmetal doping, strain engineering, defect engineering, surface functionalization, and heterostructure engineering. [29][30][31][32][33][34] With this consideration in mind, tremendous endeavours have been devoted to the synthesis of advanced metallenebased electrocatalysts to boost hydrogen production coupled with biomass upgrading. Although some reviews regarding the metallene-based catalysts for electrocatalytic reactions have been reported, a focused review on the biomass-oxidationassisted hydrogen evolution driven by rapidly developing metallenes has not been reported.…”

Recent advances of H-intercalated Pd-based nanocatalysts for electrocatalytic reactions

“…As well known, Pd-based nanomaterials are reported to be advanced electrocatalysts for electrocatalytic AOR due to their intrinsically high electrocatalytic activity. 48–51 In recent years, modifying the electronic structure of Pd has paved another pathway for substantially enhancing their electrocatalytic performance. 52–60 Incorporating H atoms into Pd lattice can tailor the d-band center of Pd and accelerate the reaction kinetics by weakening the bond between the catalyst and reaction intermediate.…”

Boosting nucleophilic attack to realize high current density biomass valorization on a tunable Prussian blue analogue

“…[8][9][10][11][12][13][14][15][16] Moreover, compared with the energy-intensive and kinetically sluggish oxygen evolution reaction (OER), the alcohol oxidation reaction (AOR) can largely reduce the energy input. 17,18 Previous reports have demonstrated that catalysts containing transition metal elements such as Ni, Co, Cu, Fe, etc. are potential alternative catalysts for the electrooxidation of alcohols due to the inherent electronegativity of the elements.…”
