“…Up to date, different methods based on physical, chemical, and biological treatments such as membrane processes, reverse osmosis, photocatalytic degradation, photo-Fenton, ozonation, oxidation, biological, as well as electrochemical procedures have been used for remediation of industrial wastewaters (Barbusiński, 2005;Farré et al, 2005;Liu et al, 2007;Dogan and Turkdemir, 2012;Ioannou et al, 2013;Zheng et al, 2013;Suresh et al, 2014;Suresh et al, 2016;Jesudoss et al, 2017;Rajan et al, 2017;Kooshki et al, 2019;Peymani-Motlagh et al, 2019a;Peymani-Motlagh et al, 2019b;Rahimi-Nasrabadi et al, 2019;Sobhani-Nasab et al, 2019aSobhani-Nasab et al, 2019c). Among the most commonly mentioned methods which are subject to restrictions, photocatalytic degradation systems act as a smart tool, because it is simple, highly efficient, and inexpensive (Basith et al, 2014;Vijaya et al, 2017;Sedighi et al, 2018;Eghbali-Arani et al, 2018;Sobhani-Nasab et al, 2019d). Furthermore, it has an easy operation under sunlight and ambient conditions and excellent prospects for biological and chemical sensing as well as has the fewer formation of disinfection byproducts.…”

The new nanocomposite with various molar ratios along with magnetic properties was fabricated via precipitation (assisted by ultrasonic) procedure. The photocatalytic effects of methylene blue (∼90% degradation for optimized sample in 100 min) for finding the optimized sample performed under visible light irradiation. Moreover, the photo-antibacterial impacts of bacteria culture environments were found with an optimized sample that had effective destruction of bacteria in comparison to control group. The cytotoxicity properties of panc1 cells and magnetic behaviors of the obtained nanomaterials were evaluated and its IC50 was about 500 mg/L. As an initial step, the structural, morphological and magnetic characteristics of the fabricated nanocomposites were evaluated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) and MAP, UV-visible diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometry (VSM) approaches. Based on SEM results, the size of nanoparticles in fabricated nanocomposite was nearly 50-70 nm for Fe 3 O 4 /SiO 2 /TiO 2 and 80-100 nm for Fe 3 O 4 /SiO 2 /TiO 2 /CeVO 4 . XRD results showed that desired nanocomposites were truly synthesized without any impurities.

“…In the spectrum of CuCO 3 (Figure part e), the peak at 810–865 cm −1 is attributed to the vibrations of the internal C−O group in the carbonate species. The absorption band at 3200−3600 cm −1 is assigned to the stretching and bending vibrations of –OH groups, due to the presence of occluded water in CuCO 3 . The absorption band at 1260–1670 cm −1 is attributed to the C=O groups of the carbonate ions and the antisymmetric stretching mode of C−O.…”

Experimental Study of the Thermal Properties of Microencapsulated Palmitic Acid Composites with CuCO₃ Shell as Thermal Energy Storage Materials

et al. 2019

A novel microencapsulated phase change material (PCM) with a Palmitic acid (PA) core and Copper (II) carbonate (CuCO 3 ) shell was successfully fabricated through a self-assembly method. Fourier transform infrared (FT-IR) spectroscopy, X-ray diffractometer (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to determine the chemical compositions, crystalloid phase, microstructure and morphology of PA@CuCO 3 microcapsules, respectively. The thermal properties and thermal stability of microcapsules were determined by differential scanning calorimetry (DSC) and a thermogravimetric analysis (TGA). The XRD and FT-IR results indicated the presence of all of the characteristic peaks of PA and CuCO 3 and proved that no chemical reaction had occurred between them. The SEM images showed a regular spherical morphology with rough surfaces for the PA@CuCO 3 microcapsule with average diameters ranged from 1.5 to 2 μm, and the TEM image confirmed the PA core to have been well encapsulated by CuCO 3 . In the DSC analysis results, the microcapsules indicated similar phase change behaviors as those of pristine PA, and the typical samples were melted at 66.9°C with a latent heat of 48.85 J/g and frozen at 55.7°C with a latent heat of 43.29 J/g for a microencapsulation ratio of 43.92%. TGA analyses indicated that the thermal stability of the PA was further improved due to the protection of the PA core encapsulated by the CuCO 3 shell.[a] Dr.step degradation behavior over a temperature range of 200-310°C, which is attributed to the decomposition of PA and CuCO 3 , respectively. It is clear from Figure 5 (parts b, c, and d) that the PA@CuCO 3 microcapsule samples all exhibited a maximum weight loss at higher temperatures in comparison with the pristine PA, which indicates that the CuCO 3 shells can improve the thermal stability of PA in the microcapsule.Using DSC, the phase change behaviors and latent heats of the pristine PA and PA@CuCO 3 microcapsules with different core/shell mass ratios were investigated.

Bimetallic oxides have attracted extensive attention due to their excellent photocatalytic properties. Co 2 NiO 4 has good electrical activity which can effectively regulate the distribution of charge. The scanning electron microscope and transmission electron microscope images of Co 2 NiO 4 showed two-dimensional uniform lamellar morphology. This kind of morphology could provide a larger specific surface area, which was conducive to improving photocatalytic water decomposing and hydrogen evolution. In addition, we combined Co 2 NiO 4 with NiWO 4 to improve the conductivity of Co 2 NiO 4 and the position of Fermi energy level, forming a p-n-type heterojunction, effectively promoting the interface charge transfer through the internal electric field, and inhibiting the electron-hole pair recombination. The photocatalytic hydrogen production of CN/NW-3 in the sensitized system reached 341.83 lmol for 5 h, which was 19 times that of pure Co 2 NiO 4 . At the same time, UV-Vis diffuse reflection and Mott-Schottky curve were used to further determine the conduction band (CB) and valence band (VB) positions of Co 2 NiO 4 and NiWO 4 , which formed a charge transport path with higher separation and transfer efficiency. This work highlights the high-efficient photocatalytic hydrogen production performance of CN/NW p-n heterojunction.
