“…Furthermore, the potential of the extract has been explored in the biosynthesis of silver nanoparticles (P. AgNPs), as both reducing and stabilizing agent. Synthesis of nanoparticles using biological agents is straightforward, inexpensive and eco-friendly [9,10]. In addition, during the stabilization process, the bioactive agents bind to the nanoparticles' surfaces, enhancing the biological activity of the nanoparticles [[11], [12], [13]].…”

This study presents the green synthesis of TiO2-clay nanocomposite using an eco-friendly method based on carbohydrates. Glucose and soluble starch function as the bioreductant and stabilizer agent during the reaction, respectively. The UV-vis analysis ascertained the formation of TiO2-clay nanocomposite presenting a distinctive absorption peak at 360 nm and an optical band gap of 4.3 eV. TEM and XRD results indicated the anatase phase of spherical TiO2-clay with a median crystallite size of 18.36 nm. EDX and XRF techniques revealed the presence of titanium, oxygen peaks, and TiO2 compound (58 wt%) along with the elemental composition of clay. The BET values of specific surface area, average pore diameter, and pore volumes are 47.48 m2g− 1, 17.39 nm, 0.19 cm3g− 1, respectively. The benign TiO2-clay nanocomposite demonstrated superior photocatalytic efficiency toward photodegradation of poly polychlorinated biphenyl pollutant in industrial wastewater with a removal rate of 98.32%, greater than untreated TiO2 NPs.

“…According to the previous studies, some of toxic gases such as CO, CO 2 , SO 2 , O 3 , VOC s , etc., have more concentration in air [3]. Nowadays, excellent properties of nanomaterials such as high surface area and high adsorption caused to use for air purification [8][9][10]. According to the most valence of equilibrium cycle, the cycle of adsorption/desorption process can be identified approximately when the adsorbent is started that the model of isotherm as fluctuation of temperature and or pressure can be applied for appraising of the maximum capacity of equilibrium axle.…”

The aim of this article was the fabrication of Al2O3/Pd(NO3)2/zeolite adsorbent through roll-coating technique for CO gas adsorption. Transmission electron microscopy (TEM), field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and energy-dispersive x-ray spectroscopy (EDX) were performed to investigate the morphological, structural, and elemental properties of Al2O3/Pd(NO3)2/zeolite adsorbent. A continuous gas analyzer KIMO KIGAZ 210 was applied for testing CO gas adsorption on as-present adsorbent in an experimental set-up. The calculated amounts of adsorption capacity at equilibrium time was 111.16 mg g-1 according to the previous published article. The Elovich, Avrami, and Fractional power kinetic models were studied for this adsorbent. The equal value of experimental and theoretical adsorption capacity at equilibrium time as well as the unit value of regression coefficient indicate that Avrami kinetic model was a suitable model to describe Co removal through Al2O3/Pd(NO3)2/zeolite adsorbent.
