In this work, the ability of the MgCaFe- Layered double hydroxide (LDH) for congo red (CR) dye removal in aqueous solution was investigated. Various parameters such as initial dye concentrations, temperature, adsorbent dosage, pH effect and agitation rate were examined and optimal conditions (10 mgL-1 of the dye concentration, 25 °C of temperature, 0.5 gL-1 of the adsorbent dosage, pH~7 and 450...

Zn-Al layered double hydroxide (LDH) nanoparticles with carbonate as the charge balancing anion in the interlayer space were synthesized using co-precipitation method. Then, the carbonate base Zn-Al LDH nanoparticles were doped with phosphate ion via anion-exchange reaction to synthesize Zn-Al-[PO43-]-[CO32-]. The structure and composition were characterized by X-ray diffraction (XRD), Fourier ...

The formation of Pd(0) in the absence of any classical reducing agent in a medium containing Mg(2+)/Al(3+) layered double hydroxide (LDH) and N,N-dimethylformamide was evidenced. XRD analysis showed the presence of crystalline phases of palladium in the Pd/LDH composite. Suzuki-Miyaura reactions in aqueous medium were carried out at room temperature, and good yields were obtained with bromoaren...

A facile enzyme-free hydrogenperoxide electrochemical sensorwas fabricated based onmultilayer ultrathin film containing Naphthol green B anions (NGB) and exfoliated nanosheets of Co–Al layered double hydroxide (LDH) via layer-by-layer self-assembly technique. The X-ray diffraction pattern indicates the superlattice structure of the filmwith repeating distance of 4.15nm; SEM and AFM images show ...

Thermal decomposition of layered zinc hydroxide double salts provides an interesting alternative synthesis for particles of zinc oxide. Here, we examine the sequence of changes occurring as zinc hydroxide chloride monohydrate (Zn5(OH)8Cl2·H2O) is converted to crystalline ZnO by thermal decomposition. The specific surface area of the resultant ZnO measured by BET was 1.3 m(2) g(-1). A complicati...

Acrylate and methacrylate anions containing double bond and carboxylic groups, were intercalated in the interlayer region of a layered double hydroxide of formula: [Zn0.66Al0.34(OH)2](NO3)0.34 0.62H2O. The intercalation compounds obtained have been characterized for their chemical composition and with different instrumental techniques (X-ray powder diffraction, thermal analysis, FT-IR absorptio...

The transition metal-based layered double hydroxides (LDHs) for high-performance supercapacitor applications were synthesized by the hydrolysis dropping method. We found that sequence of cation and anion solutions has a strong influence on microstructural electrochemical properties LDHs. NiAl LDHs obtained Ni 2+ solution into AlO 2- have obvious structures with particle size order micrometers. ...
