“…The peaks at 1396 and 1632 cm −1 correspond to the characteristic peaks of Mo−S bond vibration. 9,27 The characteristic absorption bands of the pure PANI at 1486 and 1303 cm −1 are assigned to the C=C stretching vibrations of the benzene rings and quinone units, 28 while the peaks at 1567 and 1128 cm −1 correspond to C−N stretching and in-plane =C−H bending mode, respectively. 26,27 All of the MoS 2 /PANI hybrids display characteristic peaks of MoS 2 and PANI, while the characteristic peaks of PANI and MoS 2 gradually enhance and reduce with an increase of the PANI content, respectively.…”

As a promising catalyst, MoS2 has been widely studied owing to its high chemical reactivity, excellent electrical carrier mobility, good optical properties, and narrow band gap. However, the high recombination rate of photoinduced charge carriers limits its practical application in photocatalysis. In this study, MoS2 was coupled with PANI to fabricate an S-scheme heterojunction MoS2/PANI. The synthesized products were characterized systematically, and their photocatalytic properties were evaluated by photocatalytic degradation of norfloxacin (NOR) and rhodamine B (RhB). The obtained results indicated that the fabricated MoS2/PANI inorganic–organic heterojunction displayed tremendously enhanced photocatalytic activity. The degradation efficiencies for 60 mg L–1 of NOR and RhB are 86 and 100% under the simulated sunlight irradiation for 1 h with 10 mg of catalyst, which are 13 and 47 times higher than those of pure MoS2, respectively. Interestingly, it is superior to the previously reported related materials. The remarkably enhanced photocatalytic activity of MoS2 is assigned to the high charge conductivity feature of PANI and the formed S-scheme heterojunction that result in a steric separation of holes and electrons and conserve the initial powerful redox ability of the parent catalysts. This study provides a facile method to greatly improve the photocatalytic activity of MoS2 and facilitates its application for highly efficient removal of organic pollutants, such as antibiotic drugs and organic dyes, utilizing solar energy.
