“…According to the results given in Table 5, the adsorption ability of DPA-LDH toward Pb 2+ and Cu 2+ is higher than that of the other ions. As shown in Table 5 Table 6 shows that the obtained K d values for DPA-LDH are higher than those that were reported for previous sorbents such as metal-organic frameworks [6], dodecyl sulfate based intercalated-LDHs [28], carbonate based LDHs [29], sulfide based intercalated-LDHs and materials [10,40,41], polymers [42,43], magnetic nanoparticles [44,45], ion imprinted polymers [46], layered hydrogen metal sulfides [47], and zeolites [48]. The comparison of the q m values of DPA-LDH with the same values of other sorbents presented in the literature (Table 6) for metal ions removal is indicative of the higher efficiency of DPA-LDH for the removal of heavy-metal ions.…”

“…At trace levels, some of the heavy metals such as copper and zinc are essential micronutrients for plants, living organisms, and the human body, whereas, in large amounts, they cause Wilson̕ s, Menkes, and Prion diseases [5]. On the other hand, lead, cadmium are well recognized to be highly toxic and hazardous to human health even at low concentrations [6,7]. Lead can cause central nervous system damage.…”

Six new NiCr layered double hydroxides (LDHs) intercalated with different inter-layeranions, including diphenylamine-4-sulfonate (DPA), dodecyl sulfonate (DS), pentansulfonate (PS), terephthalate (TA), fumarate (FA) and 2-ethylhexyl hydrogenphosphate (EHP), were synthesized and used to removal of Cd 2+ , Pb 2+ , Cu 2+ , and Zn 2+ ions from water samples. The maximum adsorption capacities (q m ) for the mentioned LDHs based on their inter-layer anions were DPA>DS>PS>TA>FA>DEHP. This observation highlights the key role of the structure of the inter-layer anions in the adsorption behavior of LDHs. The sulfonate-based LDHs showed better adsorption efficiency than carboxylate-based LDHs, and phosphonatebased LDHs showed the lowest adsorption efficiency. Also, at both high and low concentrations of the metal ions, the length of R-groups and the type of functional groups of inter-layer anions play a key role in the adsorption process. Subsequently, DPA-LDH, due to having the highest q m value among intercalated-LDHs, was chosen as an efficient sorbent for the removal of the metal ions from aqueous samples and its selectivity for adsorption of metal ions was investigated. DPA-LDH displayed a selectivity order of Zn 2+

Thallium(III) oxide, a degenerate n-type semiconductor, is a highly insoluble thermally stable thallium source suitable for glass, optic and ceramic applications. Although thallium oxide is an important metal oxide, its synthesis has only been sporadically studied. This review gives an overview of all reported synthetic routes for the preparation of both bulk and nanostructured thallium(III) oxide. These methods include electrochemical methods, thermal method, chemical vapor deposition (CVD), microwave irradiation, sol-gel method and one recently chemical route using potassium superoxide. In electrochemical methods, both bulk and nanostructures of thallium(III) oxide can be prepared and the amount of the deposited material, thickness of the layer or wires length depends on the deposition time matrix structure. Thermal methods are simple and effective techniques which include thermal decomposition and calcination of various precursors. By CVD and microwave irradiation we be able to synthesis bulk and nanostructures of thallium(III) oxide, respectively. A one-step, room temperature, solution synthesis of thallium(III) oxide nanoparticles with a size of about 10 nm is reported by using potassium superoxide.

“…The group of Morsali have also investigated the Zn(II)-based MOFs, [Zn 2 (oba) 2 (4-bpdb)]·(DMF) x (TMU-4), [Zn (oba) (4-bpdh) 0.5 ] n ·(DMF) y (TMU-5), [Zn (oba) (4-bpmp) 0.5 ] n ·(DMF) z (TMU-6). They found that the MOFs could be used as solid base catalysts in the Knoevenagel condensation because of the basicity of azine functionalized pores [87] and among the three MOFs, TMU-6 had a lower adsorption efficiency for metal ions than the other two MOFs, which was attributed to the greater basicity of the azine groups on the TMU-4 and TMU-5 pore walls as compared to the imine groups on the N-donor ligands on the TMU-6 pore walls [88].…”

common methods, such as hydrothermal method, solvothermal method, wet chemical method. Besides, the metalorganic coordination polymers (MOCPs) have been thought as effective templates to obtain the desired nanomaterials in the recent studies. By choosing appropriate MOCP precursors with special morphologies and under suitable experimental conditions, we can obtain the desired morphologies and even the nano-compounds that can be obtained by other methods [3,4]. Among the various divalent metal hydroxides, cadmium hydroxide [Cd(OH) 2 ] is a wide band gap semiconductor with a wide range of possible applications, including solar cells, phototransistors and diodes, transparent electrodes, and sensors, and consequently [5][6][7]. Furthermore, Cd(OH) 2 is an important precursor to prepare cadmium oxide (CdO) [8-11] by high-temperature calcination or for other functional materials such as cadmium sulfide (CdS) [12,13] and cadmium selenide (CdSe) [14-17] by reaction with appropriate compounds, which can be used as electrode additives to increase the discharge capacity of Cd-Ni batteries or pseudocapacitor and reduce self-discharge [18][19][20][21][22]. Numerous techniques have been proposed to synthesize various Cd(OH) 2 nanostructures with promising control of properties. And their potential applications and future prospects have also been discussed. Synthesis of Cd(OH) 2 nanomaterials Hydrothermal synthesisAs a common and an effective method to synthesize functional nanomaterials, hydrothermal synthesis method has the advantage of high yield, less pollution, and being easy to operate. And products with good crystallization and various morphologies can be prepared via hydrothermal Abstract Recently, Cd(OH) 2 nanomaterials have attracted attention because of their distinct properties. Cd(OH) 2 nanostructures with different morphologies have been successfully synthesized and used in various fields. In this paper, the preparation of Cd(OH) 2 nanomaterials is reviewed including hydrothermal, solvothermal, wet chemical, refluxing, microwave-assisted methods, and their applications are briefly introduced in hydrophobic and hydrophilic materials, adsorption of negative organic molecules, sensors, and electrode materials. The development trend and prospects of the preparation of nano Cd(OH) 2 are proposed.
