In this study, Au nanoparticle decorated Ni 2 P nanosheet arrays (Au/Ni 2 P) with a porous grid are synthesized using hydrothermal and electrodeposition reactions for the first time. The Au/Ni 2 P nanosheet arrays can electrocatalytically oxidize hydroquinone to produce a current for the detection of hydroquinone. A hydroquinone sensor is fabricated by Au/Ni 2 P with a porous grid, which can take full advantage of the synergistic catalysis of Au nanoparticles and Ni 2 P. The catalytic reaction sites of hydroquinone and the potential energy surface of the reaction pathway were predicted by Gaussian 09 and Multiwfn. Prominent performance was recorded for the hydroquinone sensor, attaining a wide linear range from 0.5 to 4000 μM, an excellent sensitivity of 1715 μA mM −1 cm −2 , a low detection limit of 0.26 μM, as well as reliable selectivity, repeatability and stability. Gratifyingly, the sensor could satisfy the requirements of hydroquinone determination in actual environmental water, such as in tap water and rainwater. [ABSTRACT FROM AUTHOR]
