Substituting the oxygen evolution reaction by urea oxidation (UOR) is thermodynamically more favorable for energy-saving hydrogen production. However, UOR suffers from sluggish kinetics due to its complex six-electron transfer processes combined with conversion of complicated intermediates. Herein, LaNiO3–NiO heterojunctions successfully constructed accelerate UOR. Systematic experimental investigation and theoretical calculation endorse that self-driven local charge redistribution takes...
Developing noble-metal-free catalysts for electrochemical hydrogen evolution reactions (HER) with superior stability in acid is of critical importance large-scale, low-cost production from water electrolysis. Herein, we report a highly efficient and stable HER catalyst, which composed Ni Mo2C nanocrystals supported on N-doped graphite nanotubes. This catalyst shows very low overpotential (65 mV 0.5 M H2SO4 at current density 10 mA cm–2 Tafel plot 67 mV/dec) good acidic electrolyte, promising...
A mild phosphorization process in low-temperature molten salt (NaCl-KCl-AlCl3 ) has been developed to synthesize peapod-like CoP@C nanostructures by using low-toxicity industrial PCl3 as the phosphorus source and Mg reductant at 250 °C. Importantly, high efficiency of phosphorous is achieved since only stoichiometric required complete reaction. The NaCl-KCl-AlCl3 not provides a liquid environment but also participates electron transport reversible conversion Al3+ /Al redox couple. obtained...
Early 3d transition metals are not focal catalytic candidates for many chemical processes because they have strong affinities to O, N, C, or H, etc., which would hinder the conversion of those species products. Metallic Mn, as a representative, undergoes nitridation under ammonia synthesis conditions forming bulk phase nitride and unfortunately exhibits negligible activity. Here we show that alkali alkaline earth metal hydrides (i.e., LiH, NaH, KH, CaH2 BaH2, AHs short) promotes activity Mn...
This review elaborates on the decay mechanism of aluminum anodes from five different aspects and their modification four aspects.
Silica can be converted to silicon by magnesium reduction. Here, this classical reaction is renovated for more efficient preparation of nanoparticles (nano-Si). By reducing the particle size starting materials, completed within 10 min mechanical milling at ambient temperature. The obtained nano-Si with high surface reactivity are directly reacted 1-pentanol form an alkoxyl-functionalized hydrophobic colloid, which significantly simplifies separation process and minimizes loss small Si...
