中文摘要：
采用电沉积的方法制备了Pt/石墨烯纳米复合材料,考察了该复合材料的电化学性能,用于甲醛的检测,表现出良好的检测性能。实验结果表明：在0.1 mol/L的H2SO4溶液中,Pt/石墨烯纳米复合材料修饰电极可以实现在2×10-6~2×10-3mol/L浓度范围内甲醛浓度的检测,最低检测限为1×10-6mol/L,并且具有高的灵敏度和良好的重现性。
英文摘要：
Pt / graphene nanocomposite is prepared by electrodeposition and its electrochemical performance is studied,and nanocomposite exhibits good performance for detection of formaldehyde. Experimental results indicate that the nanocomposite modified electrode can realize formaldehyde detection in the range of 2 × 10- 6~ 2 ×10- 3mol / L in 0. 1 mol / L H2SO4 solution,the lowest detection limit is 1 × 10- 6mol / L,furthermore,it has high sensitivity and good reproducibility.
