Investigation of the Photocatalytic Activity of ZnO Nanowires: Substrate Effect and Kinetics Analysis

Table 1

A comparison of diameters, number densities, and RFs of the NW samples. The NW length is around 6 μm for all samples.

Sample	Diameter (nm)	Density (μm^−2)	RF
FTO-A	70~90	3.4	5
FTO-B	30~50	7.0	5
Sapphire	30~50	7.7	5.5
Si-A	50~70	4.1	4.5
Si-B	50~70	3.3	4
