Oxygen-deficient SnO2 nanoparticles with ultrathin carbon shell for efficient electrocatalytic N2 reduction
文献摘要：
For high-efficiency NH3 synthesis via ambient-condition electrohydrogenation of inert N2,it is pivotal to ingeniously design an active electrocatalyst with multiple features of abundant surfacial deficiency,good conductivity and large surface area.Here,oxygen-deficient SnO2 nanoparticles encapsulated by ultrathin carbon layer(d-SnO2@C)are developed by hydrothermal deposition coupled with annealing process,as promising catalysts for ambient electrocatalytic N2 reduction.d-SnO2@C exhibits high activity and excellent selectivity for electrocatalytic conversion of N2 to NH3 in acidic electrolytes,with Faradic efficiency as high as 12.7％at-0.15 V versus the reversible hydrogen electrode(RHE)and large NH3 yield rate of 16.68 μg h-1 mg-1cat at-0.25 V vs.RHE in 0.1 mol L-1 HCl.Benefiting from the structural superiority of enhanced charge transfer efficiency and optimized surface states,d-SnO2@C also achieves excellent long-term stability.
