Usage

General Description

Cadmium iodide is a chemical compound with the molecular formula CdI2. It is a highly toxic, crystalline compound that often appears as a white or yellowish-white color. This inorganic compound is used in a range of applications including as a photographic fixing agent, in cloud seeding, and as a phosphor in fluorescent screens. Importantly, cadmium iodide is also used in solar cells and electronic equipment. Despite its range of uses, it raises serious health concerns due to its toxicity which can potentially cause harm to bones, kidneys and potentially carcinogenic if it's ingested or inhaled excessively.

Ag2CdI4: Synthesis, characterization and investigation the strain lattice and grain size

In this work the Ag2CdI4 nanostructures have been synthesized via a solid state reaction from reaction of AgI and CdI2 as precursors. The effect of the mole ratio of precursors, time and temperature of reaction has been optimized to achieve the best product on morphology and purity. Nanostructures have been characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman (FT-IR) techniques, X-ray energy dispersive spectroscopy (EDS) and Ultraviolet spectroscopy (UVvis). The XRD patterns of nanostructures have been used to estimate the grain sizes and strain lattice. Grain size of nanostructures is in range of 5–17 nm and the strain of lattice is changed in range of 0.0024–0.014. The band gap of these nanostructures has been estimated by DRS spectrum about 5.4 eV. Raman spectroscopy has been confirmed the XRD results and show that the Ag2CdI4 nanostructures have been synthesized. SEM and TEM images have been used for investigation of morphology of product. Results show that the best morphology and purity have been achieved in 12 h and 200 °C in 1:1 mol ratio of precursors.

Simple synthesis, characterization of cadmium bismuth iodide nanostructure and its visible-light-induced photocatalytic degradation of toxic dyes

Pollutants such as dyes, detergents, agro wastes, inorganic substances, pesticides and herbicides, etc. are the main reason for water pollution. Many toxic organic contaminants in wastewater have been degraded through photocatalysis. So, nowadays researchers have been working for the removal and degradation of organic pollutants using some metal iodides as a photocatalyst. Present work comprises the synthesis of Cadmium Bismuth Iodide photocatalyst and its precursors through simple precipitation method and solid-state reaction. Cadmium Bismuth Iodide characterizes through XRD, FESEM, EDX UV-Vis analysis. Comparative photocatalytic degradation of Azure-A and Toluidine blue was studied using an as-prepared catalyst. The impact of several factors like pH, the concentration of Azure-A and Toluidine blue dyes, amount of Cadmium Bismuth Iodide and irradiation time were examined. Increment in the reaction rate of both dyes was monitored with the help of a spectrophotometer. A tentative mechanism has been proposed for photocatalytic decomposition of both dyes.

Investigation on the thermal decomposition some heterodinuclear Ni II-MII complexes prepared from ONNO type reduced Schiff base compounds (M II=ZnII, CdII)

N,N'-bis(salicylidene)-1,3-propanediamine (LH2), N,N'-bis(salicylidene)-2,2'-dimethyl-1,3-propanediamine (LDMH2), N,N'-bis(salicylidene)-2-hydroxy-1,3-propanediamine (LOH3), N,N'-bis(2-hydroxyacetophenylidene)-1,3-propanediamine (LACH2) and N,N'-bis(2-hydroxyacetophenone)-2,2'-dimethyl-1,3-propanediamine (LACDMH 2) were synthesized and reduced to their phenol-amine form in alcoholic media using NaBH4 (LHH2, LDM HH2, LOHHH2, LACHH 2 and LACDMHH2). Heterodinuclear complexes were synthesized using Ni(II), Zn(II) and Cd(II) salts, according to the template method in DMF media. The complex structures were analyzed using elemental analysis, IR spectroscopy, and thermogravimetry. Suitable crystals of only one complex were obtained and its structure determined using X-ray diffraction, NiLACH?CdBr2?DMF2, space group orthorhombic, Pbca, a=20.249, b=14.881, c=20.565 A and Z=8. The heterodinuclear complexes were seen to be of [Ni?ligand?MX 2?DMF2] structure (ligand=LH2-, LDM H2-, LOHH2-, LACH2-, LACDMH2-, M=ZnII, CdII, X=Br-, I-). Thermogravimetric analysis showed irreversible bond breakage of the coordinatively bonded DMF molecules followed by decomposition at this temperature.
