However, ZnO porous nanorod materials with skin color have not been reported

Cui Qingyue from East China Normal University used zinc acetate and ammonia water as raw materials to prepare a porous ZnO nanoribbon structure (Chinese invention patent, publication number: CN 101182030A) by hydrothermal and pyrolysis methods, but the nanoribbon is a white powder material; Zheng Min of Soochow University and others used zinc nitrate, ammonia water and urea as raw materials to prepare pink ZnO microrod structures by high-temperature combustion method (Min Zheng, Zuo-shan Wang, Jia-qing Wu, Qing Wang, Synthesis of nitrogen- doped ZnOnanocrystallites with one-dimensional structure and their catalytic activity for ammonium perchlo-rate decomposition[J], J.Nanopart Res., 2009, 3), but the microrods are hexagonal prisms with no hole microstructure on the surface
