Preparing Mg(OH)2-based materials by electro-deposition method from magnesium- and calcium-rich brine simulant

Bin Li et al.

Summary: Pollution to the ocean caused by the disposal of reject brine is a serious environmental concern. This paper presents a method for preparing Mg(OH)(2)-based building materials from magnesium- and calcium-rich solutions through electro-deposition. The validity of this method was assessed in two scenarios, and the properties of the deposits were investigated. It was found that using brine simulant resulted in better quality deposits compared to using seawater simulant. On the micro scale, the particles grown from the brine simulant showed higher packing density and smaller size, which could positively affect the mechanical property of the deposits.

Concurrent removal of phosphate and ammonium from wastewater for utilization using Mg-doped biochar/bentonite composite beads

Huan Xi et al.

Summary: This study reports the excellent concurrent removal ability of a new adsorbent, SA-Mg@BC/BT, for phosphate and ammonium. The adsorbent has a high specific surface area and abundant functional groups, and its maximum adsorption capacities for phosphate and ammonium surpass those of other relevant adsorbents. The removal ability for phosphate remained stable in the presence of monovalent anions, while the adsorption capacity for ammonium was enhanced by divalent salts. The adsorption capacity in actual wastewater was almost the same as that in simulated wastewater, demonstrating the potential of SA-Mg@BC/BT for nutrient recovery.

Catalytic ozonation of antibiotics by using Mg(OH)2 nanosheet with dot-sheet hierarchical structure as novel nanoconfined catalyst

Jun Wu et al.

Summary: Antibiotic pollution is a major concern for sustainability, and catalytic ozonation is an efficient technique for removing contaminants in water. This study developed a nanosheet-growth technique to synthesize a Li-doped Mg(OH)(2) catalyst for ozonizing antibiotics, achieving complete removal of metronidazole in just 10 minutes. The Li-doped Mg(OH)(2) catalyst exhibited a nano-confinement effect and had a significantly higher reaction rate compared to nano-Mg(OH)(2). The synthesized Mg(OH)(2) nanosheet with a dot-sheet hierarchical structure showed excellent reusability and catalytic performance.

Hydrogen Adsorption at the Au/TiO2 Interface: Quantitative Determination and Spectroscopic Signature of the Reactive Interface Hydroxyl Groups at the Active Site

Akbar Mahdavi-Shakib et al.

Summary: Infrared spectroscopy reveals that H-2 adsorption on Au/TiO2 catalysts occurs heterolytically at the metal-support interface, generating stable protonated MSI hydroxyls. Au modifies the local structural and electronic properties of the support, leading to an increase in the basicity of electron-rich MSI hydroxyls. This synergism between Au and TiO2 results in electron-deficient Au particles and more electron-rich MSI hydroxyls, contributing to stronger Lewis acids and Bronsted bases, respectively.
