| Abstract: | 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 -3 mol/L in 0. 1 mol/L H2SO4 solution,the lowest detection limit is 1 ×10-6 mol/L,furthermore,it has high sensitivity and good reproducibility. |
