Toxic metals in water systems pose a global health risk. Thus, multifunctional water monitoring and treatment materials are indispensable. Nickel ions, a frequent heavy metal pollutant, affect ecosystem function. This study investigates the utilization of Al2O3@g-C3N4 (AlCN) nanosorbent for adsorbing Ni (II) ions from aqueous solutions.

Zr-based metal-organic frameworks (Zr-MOFs) are emerging as potential adsorbents for removing nitrogen contaminants in fuel and wastewater. Functionalized Zr-MOFs exhibited superior indole (IND) adsorption capacity than the original MOF, but the activity of the multiple adsorption sites has not been discussed.

Precious Pt metals deposited on reducible CeO2 oxide have been widely used in exhaust gas treatment. However, the high cost of Pt metals is the main barrier that prevents from applying the Pt metals. Therefore, a lot of efforts have been dedicated to reducing the Pt size as small as possible, aiming at maximizing Pt metal utilization efficiency. The smallest ultimate size that Pt metal can be deposited on CeO2 as single atom structures. Furthermore, the supported single Pt atom catalysts enhance catalytic performance and selectivity compared to Pt cluster or Pt particle counterparts.

In this work, Al-doped ZnO and Fe-doped ZnO nanoparticles have been synthesized through the coprecipitationannealing method to create new and safer UV filters for sunscreen. The effects of metal doping on phase composition, crystal structure, surface morphology, specific surface area, and elemental composition were characterized by X-ray diffraction, Raman spectroscopy, field emission electron scanning microscopy, nitrogen adsorption-desorption experiments and energy-dispersive X-ray spectroscopy, respectively.

A thermochemical model was developed to calculate the H2 adsorption isotherm of the original Mg-MOF-74 framework, and its computationally designed isoreticular employing the adsorption energies and vibrational frequencies obtained from density functional theory calculations as input variables. The model reasonably replicates the experimental adsorption isotherm of the original framework at -196˚C within the pressure range up to 1 bar

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).

Ebook "Chemical bonds outside metal surfaces (Physics of solids and liquids)" focuses mainly on the theory and concepts involved; however, it is intended for readers in chemistry, physics, and materials science who are not specialists in theory but nevertheless wish to learn more about this truly interdisciplinary area of theoretical science. The aim of the book is to present the way in which valence theory can be synthesized with the understanding of metals that has been gained over the last half century or so.

Contaminants in plating wastewater are hard to remove, especially hexavalent chromium ions. This waste stream contains a large amount of Cr6+, a highly toxic metal, potential to cause cancer. To reduce this pollution, sludge from a supply water treatment plant (DWTS) has been used to make adsorbent.

Clean water for drinking and cooking has been a serious issue in rural areas of Vietnam, which is mainly due to high-cost treatment of the available water sources in such areas. In order to reduce the treatment cost, iron impregnated ceramic granules (IICGs) was synthesized using a mixture of locally available montmorillonite and crushed rice husk (with the rice husk size < 0.2 mm, IICGs size 0.2 mm – 0.45 mm).

The adsorption of Cu(II) ions from aqueous solution onto alginic acid has been investigated based on the establishment of a relationship among pH, conductivity and the concentration of metal ion. It was shown that the adsorption of this metal ion onto alginic acid followed the pseudo-second-order reaction and was conducted by ion exchange mechanism.

Ciprofloxacin (CIP) is a second generation fluoroquinolone and is widely used in the treatment of bacterial infectious diseases in humans and animals. When released into the environment, CIP is quite stable in water and less biodegradable, so the concentration of CIP in environmental water is relatively high compared to other antibiotics.

The main aim of this investigation was to develop a low-cost solution to remove trace metals from the aqueous phase using biochar. This study investigated (i) the effect of giant reed-based biochar produced at varying temperatures in the treatment of aqueous solutions polluted with lead; and (ii) how the production of biochar at different temperatures affected its adsorption capacity for lead from the aqueous phase.

Coordination-driven self-assembly of nickel (II) ions with equimolar amounts of 1, 10 phenanthroline, and benzoic acid was used to create homonuclear nickel (II) MOF-type supramolecule. Single crystal X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, photoluminescence measurement, FT-IR, UV-visible spectroscopy, and nitrogen physisorption measurement were used to characterize the compound. The single crystal X-ray diffraction study reveals that the synthesized compound is twodimensional with pores in the structure.
