In this paper, we fabricate a novel ZnO nanowires overlapping junction (ZnO NWS-OLJ) electrode via a facile and cheap solution chemical routine. ZnO nanowires overlap and touch each other during their growth, and form ZnO NWS-OLJ. The photoelectrochemical (PEC) examination indicate that the photocurrent density of the as-prepared ZnO NWS-OLJ electrode reaches 57 μA cm⁻², which is 2 times higher than that of the ZnO nanorods (ZnO NRD) vertical array electrode at a 0 V bias potential versus Ag/AgCl. The PEC performance of ZnO NWS-OLJ electrode could be further improved by decorating Au nanoparticles on ZnO NWS-OLJ.

在本文中，我们通过一种简便而廉价的溶液化学程序制造了一种新颖的ZnO纳米线重叠结（ZnO NWS-OLJ）电极。ZnO纳米线在生长过程中相互重叠并相互接触，形成ZnO NWS-OLJ。光电化学（PEC）检查表明，所制备的ZnO NWS-OLJ电极的光电流密度达到57μAcm ^-2，是0 V时ZnO纳米棒（ZnO NRD）垂直阵列电极的光电流密度的2倍。偏电势与Ag / AgCl的关系。通过在ZnO NWS-OLJ上装饰金纳米粒子，可以进一步提高ZnO NWS-OLJ电极的PEC性能。
