The photooxidation of β-citronellol (previously shown in Scheme 8) was performed in both the small and large-scale vortex reactor. The total productivity of both products for the small-scale reactor (4000 rpm) was 10 g day –1, whereas the large-scale reactor (660 rpm) was reported to be capable of producing 1.6 kg day –1.

The SEM images (Fig. 2a–f) showed that the CMC nanocomposite fibers possessed rough surface morphologies, which was more obvious after an excessive addition of MnO.This was attributed to that the MnO particles have a larger grain size than metal Co particles. In sharp contrast to the obvious fiber-based microstructure, the sheet-like surface morphologies of the …
