A facile step-by-step approach for synthesizing copper nanoparticles (CuNPs) loaded on the wrinkled surface of reduced-graphene-oxide (Cu/rGO) was conducted using a reductant at room temperature. Multiple characterization methods were applied to specify the morphology and composition of the nanocomposites. The scanning electron microscope and transmission electron microscope of Cu/rGO show that spherical CuNps were dispersed uniformly on the surface of rGO. In addition, the characteristic peaks of Cu and carbon in energy dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy analyses spectra proved that Cu/rGO nanocomposites were synthesized. Soon afterwards, a new hydroquinone electrochemical sensor was prepared with Cu/rGO and a glassy carbon electrode. The sensor was characterized by cyclic voltammetry and electrochemical impedance spectroscopy. Hydroquinone was detected by differential pulse voltammetry using the composite electrode. Under the optimal condition, the linear response range was from 0.05 μM to 90 μM; the detection limit is 0.02 μM (S/N = 3) for hydroquinone. The electrochemical sensor exhibited high sensitivity in practical environmental water sample detection.
