Controllable growth of ZnO nanorod-carbon nanotube heterojunction arrays by lowtemperature wet chemical bath deposition method for using in dye solar cell

摘要

In this paper, we describe a cost-effective and efficient approach for the large-scale synthesis of heterojunctions between ZnO NRs and MWCNTs. Our work represents a new type of heterostructure with many benefits. The effects of precursor concentration, growth temperature and time on nanorods morphology on MWCNT were investigated systematically. It is demonstrated that the controllable growth of ZnO nanorods on MWCNT can be realized by readily adjusting the preparation parameters.
