1-Methylimidazole-2-thiol, as a kind of mercaptans, is a typical organic pollutant which has not been efficiently removed. In this study, titanium dioxide (TiO 2 ) photocatalyst based on magnetic multi-walled carbon nanotubes (MWCNTs) was synthesized via hydrothermal and sol-gel methods. The as-prepared photocatalyst was extensively characterized by X-ray diffraction (XRD), X-ray energy diffraction spectrum (EDS), transmission electron microscope (TEM), Fourier transform infrared (FT-IR) spectra, UV-Vis diffuse reflectance spectra (UV-vis DRS) and vibrating sample magnetometer (VSM). This photocatalyst of TiO 2 /Fe 3 O 4 /MWCNTs was proved to exhibit high photocatalytic efficiency and the photodegradation rate could reach nearly 82.7% for the degradation of 1-methylimidazole-2-thiol under ultraviolet irradiation. In addition, the results demonstrated that inorganic ions had a negative impact on photodegradation of 1-methylimidazole-2-thiol to varying degrees. Moreover, pH had a great and complex effect on photocatalytic degradation of 1-methylimidazole-2-thiol under ultraviolet irradiation.

“…Since the pioneering work of Fujishima and Honda in 1972, [1] TiO 2 is demonstrated to be a highly active photocatalyst, which can be explored for the photocatalytic decomposition of various organic pollutants. [2][3][4][5] In order to enhance the photocatalytic ability of TiO 2 , TiO 2 hollow nanoparticles are fabricated because of their large specific surface area. [6] Template-directed method is usually used to fabricate the TiO 2 nanoparticles with hollow structures, which is demonstrated to be a conceptually simple, straightforward and versatile route.…”

Polymerization-induced self-assembly (PISA) was used to fabricate polymeric nanoparticles via reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of benzyl methacrylate (BzMA) using diblock copolymer poly(glycerol monomethacrylate)-block-poly(2-dimethylaminoethyl methacrylate) (PGMMA-PDMAEMA-CTA) as the macro RAFT agent. The dispersion of polymeric nanoparticles with a final concentration of about 210 mg/g (solid content of 21%) was obtained via this efficient method (PISA). The resultant polymeric nanoparticles consisting of corona-shell-core three layers with weak polyelectrolyte PDMAEMA as the shell were used as sacrificial template to fabricate TiO 2 hollow nanoparticles. The negatively charged titanium precursor was absorbed into the PDMAEMA shell via the electrostatic interaction, and hydrolyzed to form polymer/TiO 2 hybrid nanoparticles. Anatase TiO 2 hollow nanoparticles were formed after removing the polymeric templates by calcination at 550 ℃. The experiments of photocatalytic degradation of methyl orange showed that the resultant anatase TiO 2 hollow nanoparticles had high photocatalytic activity and good reusability.
