“…BiOCls have many structures, including nano-flakes or plates, nano-belts, nanotubes, nano-wires, and nano-flower structures. [14] Various methods have been implemented for the synthesis of the described structures, among which the hydro/solvothermal and sedimentation methods have received more attention. [13d,15] However, the difficult operating conditions, such as high operating temperature and the need for a long time, as well as the use of hazardous solvents, were noteworthy points in the synthesis of these nanoparticles (Figure 1).…”

A safe, green, and cost‐effective procedure is introduced for synthesizing bismuth oxychloride (BiOCl) nanoparticles as an alternative to the time‐consuming ones with hazardous chemicals. In this regard, BiOCl was synthesized in both nanoplates and nanoflowers morphologies employing choline chloride: a urea‐based deep eutectic solvent, as a green solvent through the popular solvothermal and anion exchange synthesis approach. Accordingly, nano‐flowers and nano‐plates of BiOCl were synthesized by exposing {010} and {001} facets, respectively, while different characterization techniques showed excellent patterns and high purity of the synthesized nanoparticles. They are exploited as electrode modifiers for fabricating a high‐performance electrochemical nickel ion sensor to control the quality of water, and industrial waste liquor concentrates. The adsorption stripping voltammetry technique revealed that the electrode used for nickel detection with BiOCl nano‐plates was more sensitive than with BiOCl nano‐flowers. To achieve optimal electrochemical values for the proposed sensor, variables interactions are investigated using the central composite design method. The limit of detection, the electron transfer coefficient, and the number of transferred electrons were obtained to be 0.26 μm, 0.166, and 1, respectively. Evaluating the sensor application in the presence of other heavy metal cations showed its promising capability of nickel ion detection in real samples.

“…Tan et al synthesized Fe-HZSM-5, Mn-SBA-15, Cuanalcime, and Bi-NaP, which exhibit favorable performance in electro-catalysis, organic synthesis, and sewage disposal as compared with the un-doped zeolites. [16][17][18][19] Due to the advantage of shape selection, acid-base catalysis, and substance separation, the zeolites doped with heteroatoms are extremely promising in various industrial applications.…”

In‐situ synthesis of NaP zeolite doped with transition metals using fly ash

et al. 2019

Here, a novel approach has been proposed to synthesize NaP zeolite adsorbents doped with transition metals (M‐NaP) using the Na2SiO3 and NaAlO2 compounds extracted from fly ash via activation and stage treatment. The preparation process of M‐NaP employed the in‐situ synthesis in combination with organic complexation method. The effects of the addition amounts and valence state of transition metals on the zeolite products were investigated. The crystalline phase, morphology, and particle size of M‐NaP were characterized using X‐ray diffractometry (XRD), Scanning electron microscopy (SEM), and Laser particle size analyzer (PSD). The doping process was investigated using X‐ray photoelectron spectroscopy (XPS) and Materials Studio. The adsorption performance of M‐NaP was tested by the adsorption of Zn2+. The optimal molar ratio of n(Al2O3)/n(M) was identified as 8:1 for Co–NaP, Ni–NaP, and Fe–NaP, compared with 6:1 for Ti–NaP. The influence of transition metals on adsorption was: Co–NaP > Ni–NaP > Ti–NaP > Fe‐NaP. Due to largest surface area of Co–NaP (162.5 m2/g, five times than that of NaP‐RAW), the maximum removal rate of Zn2+ was above 99.50% at 25°C. The existence state of transition metals in M‐NaP primarily included: isomorphous substitution and balance of the skeletal charge, with the latter in majority. The simulation of Materials Studio indicates that Si at T4 was first substituted and then, Si at T3 opposite T4 was replaced when the replacement of Si in different sites occurred.
