In this paper, a simple and feasible method for the preparation of a graphitic carbon nitride and Zn-Al Layered Double Oxides composite is reported. The precursor of the composite material is synthesized by double titration in melamine dispersion solution, which is helpful for incorporating evenly. Then, through calcinating, the composite can be readily formatted to a three-dimensional morphology and a larger specific surface. Structure and morphology analyses for the composite material are characterized by Fourier Transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy and X-ray diffraction. Furthermore, Tafel, cyclic voltammetry and charge-discharge cyclic tests show that the introduction of the graphitic carbon nitride improves the corrosion resistance of the active material, and boosts the cycle life of the zinc anode. After 1800 cycles at 5C, the discharging capacity of the composites material can maintain at 503 mAh g(-1), with the retention rate of 92.3%. This is related to the uniform nucleation sites produced by the annular micro electric field in graphitic carbon nitride and the high content of N. This newly designed electrode materials may provide a promising candidate for high-performance nickel-zinc secondary batteries and other zinc batteries. (C) 2019 The Electrochemical Society.
