Facile preparation of a self-assembled Artemia cyst shell–TiO2–MoS2 porous composite structure with highly efficient catalytic reduction of nitro compounds for wastewater treatment
The catalytic reduction of nitro compounds is currently a hot research area, how to efficiently and stably degrade such toxic and harmful substances has become the research goal of many researchers. In this work, an Artemia cyst shell (ACS)–TiO2–MoS2 ternary porous structure was proposed and prepared as a catalyst for the reduction of 2-nitroaniline (2-NA) and 4-nitrophenol (4-NP). The ACS has a large number of porous structures, exhibits a good binding ability with TiO2 and MoS2, and provides a large number of active sites for the catalytic reduction process. The obtained composite material has a good reduction effect on 4-NP and 2-NA, with a good stability and recyclability, which is obviously higher than the reduction effect of ACS–TiO2 and MoS2 under the same conditions. This work provides ideas for the design of porous catalytic materials.
