外文摘要：Replacing oxygen evolution reaction with thermodynamic favored hydrazine oxidation reaction (HzOR) is an effective strategy for energy-saving hydrogen (H2) production, although electricity input remains indispensable. Herein, an asymmetric hydrazine-water fuel cell (HWFC) is presented by coupling alkaline HzOR and acidic hydrogen evolution reaction (HER), thereby achieving co-generation of H-2 and electricity output via further reaping the electrochemical neutralization energy. Heterostructured RuTe2-Ru nanoparticles in situ embedded in carbon nanofibers (RuTe2-Ru@CNFs) is fabricated by an electrospinning-assisted synthetic strategy, showing superior HER and HzOR catalytic performance. The asymmetric HWFC of RuTe2-Ru@CNFs||RuTe2-Ru@CNFs delivers an open-circuit voltage of 0.95 V with a maximum power density of 17.1 mW cm(-2) at 48.7 mA cm(-2). Theoretical investigations elucidate the Mott-Schottky effect at the RuTe2-Ru heterointerface, leading to the wellmodulated electronic structure for the intrinsic catalytic enhancement. Moreover, the overall synthetic strategy is generalized to fabricate other transition metal tellurides-based and Ru selenides-based nanofibers for various potential applications.
