Summary: The muscovite mica clay-graphene oxide-maghemite-magnetite (gamma-Fe2O3-Fe3O4) composite was used for the adsorption of caesium(I) and cobalt(II). The composite showed a layered structure with irregularly shaped pores on the surface. Adsorption of ions was influenced by initial concentration, pH (except for caesium), mass of adsorbent, temperature, and contact time. The high adsorption capacity of the composite could be attributed to its functional groups, active sites, or multilayer adsorption. The adsorption mechanism involved electrostatic interactions and ion exchange.

Summary: This study evaluated the spatial variability of magnetic minerals and the potential of mass-specific magnetic susceptibility (chi(lf)) to recognize minimum areas of phosphorus adsorbed (P-ads). The results showed that chi(lf) was able to differentiate soils from their parent material and could be used as a component of pedotransfer functions (PTF) for indirect quantification of P-ads in the soil. Additionally, chi(lf) was more sensitive than X-ray diffraction (XRD) analysis in quantifying ferrimagnetic minerals. The spatial pattern of ferrimagnetic minerals indicated that Mh originated from the direct oxidation of Mt.

Summary: NiCo2O4 nanowire array on carbon cloth (NiCo2O4/CC) is proposed as a highly active electrocatalyst for ambient nitrate (NO3-) reduction to ammonia (NH3). It achieves a high Faradic efficiency of 99.0% and a large NH3 yield up to 973.2 mu mol h(-1) cm(-2). The superior catalytic activity comes from its half-metal feature and optimized adsorption energy due to the existence of Ni in the crystal structure.

Summary: One-dimensional carbon-coated tungsten-doped molybdenum oxide nanowires (WMO@C) were prepared through a hydrothermal method to address the harmful effects of toxic dyes and infectious bacteria. The ternary nanocomposites of WMO@C and graphitic carbon nitride (gCN) were synthesized to enhance the photocatalytic and antibacterial activities for environmental remediation. The integration of gCN reduced the crystallite size of WMO@C to 3.53 and the synthesized nanophotocatalyst exhibited 1D nanowires with an average diameter of 192.33 nm. The WMO@C/gCN nanocomposites effectively degraded colored organic contaminants and inhibited the growth of P. aeruginosa and S. aureus microbes, with degradation rates of 91% for MB, 89% for CV, 92% for MG, 65% for benzimidazole, and 69% for benzoic acid under visible light after 120 minutes. The superior photocatalytic performance of WMO@C/gCN was attributed to its enlarged surface area, reduced electron-hole recombination rate, enhanced charge transfer capacity, and strong redox ability due to the chemical bonds formed between gCN and WMO@C nanowires. The study also investigated important reaction parameters such as pH, temperature, dye concentration, and photocatalyst dose. The facile synthesis route and excellent photodegradation and antimicrobial performance suggest that WMO@C/gCN nanocomposites hold great potential for environmental remediation.

Summary: The hydrothermal approach was used to synthesize gCN supported carbon coated Lanthanum doped tungsten oxide (C@LWO/gCN) composite. The photodegradation of malachite green (MG), crystal violet (CV), and methylene blue (MB) cationic dyes was carried out using the prepared C@LWO/gCN composite. Characterization techniques such as XRD, FESEM, EDX, FTIR, BET, and UV/Vis spectroscopy were used to analyze the synthesized samples. The results showed that the incorporation of La ions into WO3 lattice and the reduced band gap of the doped sample significantly enhanced the photodegradation capability of the material.

Summary: The rGO-supported C@Nd2O3 photocatalyst was synthesized using a facile chemical approach and ultrasound radiations to enhance its photocatalytic performance. The synthesized samples were characterized for crystal structure, surface morphology, and chemical composition using UV, XRD, FT-IR, and FESEM. The ternary composite C@Nd2O3/rGO exhibited higher photocatalytic activity than C@Nd2O3, with a 90.93% removal of the dye under 60 min of UV exposure. The improved photocatalytic efficiency can be attributed to the heterojunction formation, high charge separation, and low recombination rate of photogenerated electron-hole pairs.
