“…For example, the 20% Cu2O/MWCNT catalyst exhibited IR bands around 622 cm -1 , which is the characteristic of the lattice vibrations of the Cu2O [31] present on the surface of the carbon nanotubes. Furthermore, the FT-IR spectrum of the 20% CuI/MWCNT catalyst contained absorption bands at 611 and 495 cm -1 , which are the two characteristic vibrations of γ-CuI [32]. The results of these FT-IR studies therefore confirm that the Cu species have been successfully deposited on the MWCNTs.…”

“…2. In an fcc crystal system, the most intense peak is due to the (1,1,1) plane [33] and the indexed XRD pattern of CuI shows (111) as the most intense peak. Using Scherrer's formula, the mean crystallite size of copper iodide was calculated to be 89.1 nm.…”

Purging of heavy metals like chromium and manganese from water using various adsorbents is the need of the hour for our environment. Copper iodide nanoparticle (CuI NP) has garnered a lot of attention due to its singular physical and chemical properties. The present study reports the of use of green synthesized CuI NP using Hibiscus rosa-sinensis L. flower extract which contains the anthocyanin, cyanidin-3-sophoroside (acts as both reducing and capping agents) in the removal of aqueous Cr(VI) and Mn(VII) ions. The synthesized CuI NP was characterized and was found to be nanocrystalline in nature, showing the presence of some surface crystal defects and having a high surface area making it a good adsorbent with adsorption capacities of 169.5 mg/g for Cr(VI) and 200 mg/g for Mn(VII) ions. The kinetics of metal removal was probed. The removal of metals was also probed using Freundlich and Langmuir adsorption models.

“…6B) showed major weight loss occurring beyond 568-592°C, which corresponds to the melting temperature of CuI [26]. These major weight loss zones which extend up to 745-776°C can be associated with the loss of iodine in the samples [1,12].…”

“…CuI has been prepared through two basic chemical routes: iodination and precipitation reaction. Iodination is a gas-solid phase reaction, involving iodine vapor and a thin film of copper or a copper salt [11,12]. Precipitation is usually conducted in a solution medium containing copper salt and potassium iodide, together with a reducing agent and a stabilizing agent [13,14].…”

CuI nanocrystallites were synthesized via a red cabbage-mediated one-pot method at ambient temperature. Red cabbage extract functioned as reducing agent, converting Cu(II) into Cu(I) and as a capping agent stabilizing the CuI nanocrystallites. The resulting material was characterized using X-ray powder diffraction, scanning electron microscopy with energy dispersive X-ray spectroscopy, differential scanning calorimetry, thermal gravimetric analysis, and UV-Vis spectroscopy. It was also characterized as a solid-state colorimetric sensing reagent for elemental Hg 0 vapor through a smartphone camera-based digital image analysis. The sensor exhibited a colorimetric response to Hg 0 vapor at a concentration range of 11.4-32.6 ppb v Hg 0 with detection limit of 3.9 ppb v Hg 0 , indicating the capability of the sensor to detect the current threshold exposure limit set by the World Health Organization (6.1 ppb v ). The sensor performance characteristics confirm that the green-synthesized CuI can be a suitable colorimetric sensitive layer for detection of Hg 0 vapor.
