摘要:
以三聚氰胺为前驱体,采用一步煅烧法制备了二维类石墨相氮化碳(g-C3N4)。研究了煅烧温度对g-C3N4的结构和电化学性能的影响,并探讨了其在超级电容器中的应用。实验发现,在550 ℃下煅烧得到的g-C3N4具有最高的比电容。当电流密度为1 A·g-1时g-C3N4的比电容为52.8 F·g-1,并且在50 mV/s的扫描速率下经过10 000次循环后其比电容保留率达到82.6%。结果表明,通过煅烧三聚氰胺制备的g-C3N4具有二维层状多孔结构,因而表现出较好的电化学性能,特别是g-C3N4可以通过与其他材料的复合进一步提升其电化学性能,有望在超级电容器等储能器件中得到广泛应用。
Abstract:
Two-dimensional graphitic carbon nitride (g-C3N4) was successfully prepared from the precursor of melamine by one-step calcination method in this paper. The effect of calcination temperature on the structure and electrochemical properties of g-C3N4 was investigated,and its application in supercapacitors was discussed. The experiment shows that the best specific capacitance of g-C3N4 is obtained at the calcination temperature of 550 ℃. The specific capacitance is 52.8 F·g-1 at the current density of 1 A·g-1. Furthermore,the specific capacitance retention rate is 82.6% after 10 000 cycles at a scan rate of 50 mV/s. The results indicate that g-C3N4 prepared by the calcination of melamine exhibits good electrochemical properties due to its two-dimensional layered porous structure,especially,the electrochemical properties of g-C3N4 can be further improved through the combination with other materials,demonstrating wide applications in energy storage devices including supercapacitors etc.
