Figure 5From: Efficient solar photocatalyst based on cobalt oxide/iron oxide composite nanofibers for the detoxification of organic pollutantsTypical plots. (a) Change in the absorption spectrum. (b) Comparison of change in absorbance vs. irradiation time. (c) Comparison of percentage of degradation vs. irradiation time. (d) Pseudo-first-order kinetics for AO at pHÂ 7.0 and 10.0 in the presence of the composite nanofibers.Back to article page
