The present objective of this work is to find photoactive materials capable of facilitating visible light-driven redox reactions between CO2 and H2O. Our research is primarily focused on the incorporation of nitrogen (N) into the crystal lattice of titanium dioxide (TiO2) and its deposition onto Fe-MIL-88B to improve light absorption properties, minimize recombination of photo-generated electron-hole pairs, and increase CO2 adsorption capacity.

Harvesting microalgae by centrifugation and filtration is very costly, affecting technical and economical feasibility of downstream processing of algal biomas to bioproducts. Flocculation is a potential technique for recovery of algae biomass. Particularly, flocculation using magnetic nanoparticles offers high separation efficiency due to their high surface area and magnetic properties. I

In this study, we synthesized magnetic activated carbon (MAC) derived from Litsea glutinosa seeds, which was applied to eliminate methylene blue and nickel ions in the aeration tank of the biological treatment system. Structural characteristics and adsorption properties of MAC were studied. The obtained results revealed that the removal efficiency of these pollutants significantly improved as a combination of MAC and activated sludge, especially in the case of nickel ions removal.

In this work, nano-SiO2 have been used as nanocarriers for loading Ce(III) ions (SiO2@Ce3+). After loading, silane coupling agent has been used to modify these nanocarriers (m-SiO2@Ce3+). Then, these modified nanocarriers were added as green inhibitors into the inner epoxy coating matrix, which was based on the epoxy resin (DER 671X75) and hardener (polyamide Epicure 3125). Morphological study by FE-SEM showed that the spherical nanoparticles (mSiO2@Ce3+) were in size < 100 nm and dispersed rather homogeneously into the polyme matrix.

In this work, a bimetallic Ni-Cu-BDC metal-organic framework system was developed via solvent thermal approach with using an organic ligand recycled from waste plastic. The physical properties of Cu-BDC and bimetallic Ni-Cu-BDC were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and N2 isotherms adsorption-desorption (BET).

In ebook "Catalysis with supported size-selected Pt clusters: Fundamental UHV and applied ambient experiments" Florian Schweinberger investigates the influence of the precise size of catalytically active species on reactivity. In order to do this he carries out studies both in UHV and under ambient conditions for supported, size-selected Platium clusters (8-68 atoms). Schweinberger probed the electronic structure, adsorption properties and reactivity of two olefins on surfaces and Pt clusters in the submonolayer range.

The distinctive properties of bentonite, including hydration, swelling, water absorption, ion adsorption, high viscosity, and thixotropy make it a valuable material for many applications in geotechnical engineering such as hydraulic barriers, drilling slurry, and landfill liners. This study introduces gellan gum as a friendly environmental additive that improves bentonite slurry stability when bentonite is used for soil stabilization during excavation in emergency response.

This photocatalyst's high degradation efficiency is attributed to the synergistic effect of plasmon-induced visible light-harvesting due to Ag and enhanced adsorption and electronetransport properties due to rGO. It is found that the Ag-induced surface plasmon characteristics of the nanocomposites are sensitive to rGO concentration.
