Bamboo-like N-doped carbon nanotubes encapsulating M(Co,Fe)-Ni alloy for electrochemical production of syngas with potential-independent CO/H2 ratios
文献摘要：
The electrochemical conversion of CO2-H2O into CO-H2 using renewable energy is a promising technique for clean syngas production.Low-cost electro-catalysts to produce tunable syngas with a potential-independent CO/H2 ratio are highly desired.Herein,a series of N-doped carbon nanotubes encapsulating binary alloy nanoparticles(MxNi-NCNT,M=Fe,Co)were successfully fabricated through the co-pyrolysis of mela-mine and metal precursors.The MxNi-NCNT samples exhibited bamboo-like nanotubular structures with a large specific surface area and high degree of graphitization.Their electrocatalytic performance for syngas production can be tuned by changing the alloy compositions and modifying the electronic structure of the carbon nanotube through the encapsulated metal nanoparticles.Conse-quently,syngas with a wide range of CO/H2 ratios,from 0.5:1 to 3.4:1,can be produced on MxNi-NCNT.More importantly,stable CO/H2 ratios of 2:1 and 1.5:1,corresponding to the ratio to produce biofuels by syngas fermentation,could be realized on Co1Ni-NCNT and Co2Ni-NCNT,respectively,over a potential window of-0.8 to-1.2 V versus the reversible hydrogen electrode.Our work provides an approach to develop low-cost and potential-independent electrocatalysts to effectively pro-duce syngas with an adjustable CO/H2 ratio from electrochemical CO2 reduction.
