Synthesis, Characterization, and Applications of ZnO Nanowires
Table 1
Comparison of different ZnO nanostructures used in photocatalytic applications.
| Nanoparticles | Nanowires | Nanothin film | Advantages | Disadvantages | Advantages | Disadvantages | Advantages | Disadvantages |
| Could be suspended in a solution | Particle aggregation in a solution leads to a reduced surface area | Growth could be well aligned on most substrates | Growth conditions are more restricted | Coated on certain substrates | Lower performance because of small surface area | High performance because of larger surface areas | Posttreatment for catalyst removal is required | Offer larger surface area compared to nanothin film | Lower surface area compared to nanoparticles | Posttreatment for catalyst removal is not required | | | Difficult to recover all the catalyst | Posttreatment for catalyst removal is not required | | | | | | Lower crystallinity and more defects | | | |
