第一次主要是利用氯化锂和氯化钠反应生成离子溶液离子被吸附在纳米线表面使其表面电荷变为正电荷The first step of the preparation of ZnO nanowire array light anode is to prepare two chemical bath solutions. The first reaction mainly uses lithium chloride and sodium chloride to generate ionic solution, and the ions are adsorbed on the surface of nanowires, making its surface charge positive.
