Shifa Wang et al.

Summary: A simple two-step method was developed to fabricate ternary heterojunctions of YMnO3/CeO2/MgAl2O4 composite photocatalysts, which exhibited good adsorption capacity and photocatalytic activity. The GA model showed the best predictive ability for the adsorption capacity. The YCM photocatalysts displayed high optical absorption coefficient, charge carrier transfer and separation efficiency, adsorbed oxygen concentration and interface defect, high adsorption capacity, and photocatalytic activity. This study demonstrated the huge potential of YCM composite photocatalysts for eco-friendly adsorption of dye and degradation of drugs.

CTAB-assisted synthesis of Bi2MoO6 hierarchical microsphere and its application as a novel efficient and recyclable adsorbent in removing organic pollutants

Chaoli Chen et al.

Summary: Hierarchical microspheres of Bi2MoO6 (BMO) were synthesized using a solvothermal method with CTAB as surfactant. The synthesized BMO showed efficient and recyclable adsorption of organic pollutants, as demonstrated by investigating the adsorption kinetics, isotherms, and thermodynamics of methylene blue (MB) onto the BMO adsorbent. The BMO adsorbent can be easily regenerated via calcination in air and exhibits excellent reusability. Further studies showed its adsorption capability in removing various organic pollutants at different pH environments.

Surface doping of Bi4Ti3O12 with S: Enhanced photocatalytic activity, mechanism and potential photodegradation application

Tingting Cheng et al.

Summary: In this study, S element was doped into the surface of BTO crystals to enhance their photocatalytic activities in decomposing organic pollutants. The S-doped-BTO samples demonstrated improved visible-light adsorption and separation efficiency of photogenerated electron-hole pairs. Among the different x%S-BTO samples, 3.3%S-BTO showed the highest photocatalytic activity, with a performance 10.1 times higher than that of pristine BTO. The study also investigated the effects of inorganic anions and pH values on the photocatalytic performance of the optimal 3.3%S-BTO, as well as its photodegradation of other organic pollutants. The enhanced photocatalytic mechanism for the S-doped-BTO photocatalysts was proposed and discussed.

Morphology modulation of hollow-shell ZnSn(OH)6 for enhanced photodegradation of methylene blue

Yufen Gu et al.

Summary: The morphology of ZnSn(OH)(6) nanoparticles plays a decisive role in their photocatalytic performance. In this study, shell-like hollow ZnSn(OH)(6) nanocubes with uniform particle size distribution and superior dispersion were successfully prepared through a hydrothermal method under suitable conditions. The effects of hydrothermal time, temperature, pH, and surfactant on the microscopic morphology and photocatalytic degradation of methylene blue dye were investigated. It was found that the differences in morphology led to differences in physicochemical properties, such as bandgap and charge transfer resistance, and ultimately affected the photodegradation efficiency. By adjusting the hydrothermal parameters or using different surfactants, the microscopic morphology and photocatalytic performance of ZnSn(OH)(6) could be effectively improved.
