Integrating hydrogen evolution reaction(HER)with hydrazine oxidation reaction(HzOR)has an encouraging prospect for the energy-saving hydrogen production,demanding the high-performance bifunctional HER/HzOR *** phosphide/doped carbon composites have exhibited superior activity towardmultiple electrocatalytic *** explore the decent water-soluble precursors containing bothNand P elements is highly attractive to facilely prepare metal phosphide/doped carbon ***,as one kind ecofriendly biomolecules,adenine nucleotide was first employed to selectively fabricate the highly pure RuP nanoparticles embedded into porous N,P-codoped carbons(RuP/PNPC)with a straightforward“mix-and-pyrolyze”*** newly prepared RuP/PNPC only requires 4.0 and−83.0 mV at 10 mA/cm^(2) separately in alkaline HER and HzOR,outperforming most of reported electrocatalysts,together with the outstanding neutral bifunctional ***,the two-electrode alkaline and neutral overall hydrazine splitting both exhibit significant power-efficiency superiority to the corresponding overall water splitting with the voltage difference of larger than 2 V,which can be also easily driven by the fuel cells and solar cells with considerableH2 *** report innovates the N-and P-bearing adenine nucleotide to effortlessly synthesize the high-quality RuP/doped carbon composite catalysts,highly potential as a universal platform for metal phosphide-related functional materials.
