Simple, Green and Low-Cost Ni Nanoparticles/Tissue-Derived Nitrogen-Doped Porous Carbon Nanocomposites as an Efficient Electrocatalyst for Methanol Oxidation Reaction

In this work, green and low-cost Ni Nanoparticles/Tissue-derived Nitrogen-doped Porous Carbon Nanocomposites (NiNPs/T-dNPCNs) are prepared through a simple one-step pyrolysis process. The surface morphology composition of the NiNPs/T-dNPCNs characterized by X-Ray Diffraction (XRD), Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES), Scanning Electron Microscopy (SEM), Transmission (TEM) X-ray Photoelectron Spectra (XPS). modified glassy carbon electrode (NiNPs/T-dNPCNs/GCE) exhibits good electrocatalytic activity to Methanol Oxidation Reaction (MOR) in alkaline solution. Among them, mass NiNPs/T-dNPCNs800 (carbonization at 800 ℃) is 3,349 mA·mgNi-1, which much higher than that carbonized other temperatures (600, 700, 900 ℃). addition, 6.91 times commercial Pt/C. NiNPs/T-dNPCNs800/GCE also displays high stability, fast reaction kinetics well resistance monoxide poisoning. Therefore, as new biomass-derived non-noble metal MOR catalyst, will play an inspirational role development catalyst.
