Summary: A facile soft-templating strategy was reported for precisely engineering the porous architectures of multicomponent PdCuBP mesoporous nanospheres, resulting in three types of mesoporous nanospheres with distinct porous structures. The quaternary PdCuBP dMSs exhibited remarkably high catalytic activity and better stability for electrocatalytic ethanol oxidation reaction, which was attributed to their unique porous architecture and elemental composition advantages.

Summary: This study describes the synthesis of rod-like 1D Fe2O3/MoO3 heterojunction and its high photocatalytic efficiency for tetracycline degradation. The nanocomposites also exhibit superior recyclability and stability due to efficient electron-hole transport in the Fe2O3/MoO3 nanorods. The remarkable photocatalytic performance is attributed to the type-II alignment in the nanorods, facilitating the participation of (OH)-O-center dot and h(+) reactive radicals.

Summary: This study compared the photocatalytic activities of active photocatalysts, including AgBr, ZnO, BiOI, and Cu2O, in the presence of a-MoO3. The results showed that a-MoO3 strongly inhibited the photocatalytic activity of TiO2, BiOI, Cu2O, and ZnO, but had no effect on AgBr. Therefore, a-MoO3 could be an effective inhibitor for evaluating newly explored photocatalysts.

Summary: The presence of alpha-MoO3 significantly influences TiO2 photocatalytic performance and dye adsorption, with the (0 4 0) facet growth enhancing photocatalytic activity while decreasing adsorption affinity for cationic dyes. The solubility of alpha-MoO3 depends on the proportion of the (0 4 0) facet, affecting both adsorption and photocatalytic behaviors of the oxide. Evaluating photocatalytic activity of alpha-MoO3 with cationic dyes requires careful consideration due to the interaction between adsorption and photocatalytic processes.

Summary: Micellar-enhanced ultrafiltration is a surfactant-based method to remove low concentrations of contaminants from water and wastewater streams, increasing the permeate flux. The parameters influencing MEUF include surfactant types, membranes, pressure, etc. However, the reviewed data indicates gaps in MEUF studies, such as the lack of information regarding important parameters and imprecise measurements of CMC. The challenge for future industrial-scale applications is to study MEUF on a pilot scale using industrial wastewater.

Summary: This study demonstrates the fabrication of a highly efficient ternary heterostructure photocatalyst composed of ferroelectric BaTiO3 (BTO), semiconductor MoO3, and plasmonic silver nanoparticles (Ag NPs). The BaTiO3/MoO3/Ag (BMA) heterostructure exhibits superior photodegradation and photocatalytic efficiency compared to its binary counterparts. The enhanced photocatalytic activity in the BMA heterostructure is attributed to the enhanced interfacial electric field and electron transfer towards the top Ag NPs layer. The improved charge carrier generation and separation in the BMA heterostructure are evident from the higher resistive switching ratio, increased difference in voltage minima, and enhanced photocurrent generation observed in the I-V characteristics.
