This study investigated the structural, morphological, and optical absorption of three separate perovskites (NaPbI 3 , CsPbI 3 , and LiPbI 3) developed by a lowcost and massive hydrothermal production technique. For all samples, X-ray diffraction (XRD) measurement demonstrated the growth of perovskites in the hexagonal phase along (002) orientation. From the scanning electron microscope (SEM) analyses, the perovskites have mixed morphologies between nano/micro rods and nano/microdiscs. In the visible field, NaPbI 3 demonstrated stronger light absorption than CsPbI 3 and LiPbI 3. The prepared perovskites were tested under visible light as working electrodes for water splitting reactions using Na 2 S 2 O 3 electrolyte. With 2.76% at 405 nm, the NaPbI 3 perovskite photoelectrode in accordance with its optical properties showed the highest incident photon-to-current efficiency (IPCE) among the studied perovskites. Also, the NaPbI 3 perovskite demonstrated higher PEC performance with an H 2 production rate of 38 μmolh −1 cm −2 than many other reported perovskites. The studied perovskites have high stability and reproductivity for the photoelectrochemical H 2 production.

“…Various physical, chemical, and biological dye removal procedures have been reported. More precisely, coagulation, reverse osmosis, membrane separation, electrochemical, dilution, filtration, flotation, softening, and reverse osmosis techniques were used for this suggestion [ 15 , 16 , 17 ]. In comparison to the other methods, adsorption is the most convenient since it is inexpensive, simple, requires less maintenance, is easy to handle, and creates smaller amounts of sediment [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ].…”

Fabrication and Application of Zeolite/Acanthophora Spicifera Nanoporous Composite for Adsorption of Congo Red Dye from Wastewater

et al. 2021

Systematic investigations involving laboratory, analytical, and field trials were carried out to obtain the most efficient adsorbent for the removal of congo red (CR) dye from industrial effluent. Modification of the zeolite (Z) by the Acanthophora Spicifera algae (AS; marine algae) was evaluated in terms of adsorption capability of the zeolite to remove CR dye from aqueous solution. The zeolite/algae composite (ZAS) was fabricated using the wet impregnation technique. The AS, Z, and the synthesized ZAS composite were analyzed utilizing various characterization techniques. The newly synthesized ZAS composite has an adsorption capacity that is significantly higher than that of Z and AS, particularly at low CR concentrations. Batch experiments were carried out to explore the effects of different experimental factors, as well as the dye adsorption isotherms and kinetics. Owing to the presence of intermolecular interactions, the computational analysis showed that the adsorption of the CR molecule on zeolite surfaces is exothermic, energetically favorable, and spontaneous. Furthermore, growing the zeolite surface area has no discernible effect on the adsorption energies in all configurations. The ZAS composite may be used as a low-cost substitute adsorbent for the removal of anionic dyes from industrial wastewater at lower dye concentrations, according to the experimental results. Adsorption of CR dye onto Z, AS, and ZAS adsorbents was adequately explained by pseudo-second-order kinetics and the Langmuir isotherm. The sorption mechanism was also evaluated using Weber’s intra-particle diffusion module. Finally, field testing revealed that the newly synthesized adsorbent was 98.0% efficient at extracting dyes from industrial wastewater, proving the foundation of modern eco-friendly materials that aid in the reuse of industrial wastewater.

A comprehensive study that combined both experimental and computational experiments was performed to evaluate the usage of organo-metal oxide nanocomposite for the elimination of disperse red 60 dye (DR) from aqueous solutions. Chitosan was modified by Schiff base to form nanoneedles chitosan-4-chloroacetophenone derivative. The derivatives were then impregnated with CeO2–CuO–Fe2O3 or CeO2–CuO–Al2O3 metal oxides to prepare a novel quarternary organo-metal oxide nanocomposite. The novel nanocomposite, chitosan-4-chloroacetophenone/CeO2–CuO–Fe2O3 (CF) and chitosan-4-chloroacetophenone/CeO2–CuO–Al2O3 (CA) are cheap and effective nano adsorbents that can be used for the uptake of DR from aqueous solution. The CF and CA nano-composites were characterized using different techniques. Moreover, the effect of adsorption parameters (initial DR concentration, time of contact, pH, temperature, and adsorbent mass) as well as CA and CF reusability tests were performed. Langmuir adsorption isotherm and pseudo-second-order kinetics models were best fitted with the adsorption process. The maximum amount of DR adsorbed was 100 mg/g on CF and CA at pH 2 and 4, respectively with a physical spontaneous, and exothermic adsorption process. Monte Carlo (MC) simulation studies indicated the adsorption of DR molecule on the CF and CA surfaces following a parallel mode in most of all studied configurations, confirming the strong interactions between the DR and surfaces atoms of CF and CA. The molecular structure analysis of DR dye adsorbed on the surface of CF and CA indicated that the adsorption process related to Van der Waals dispersion force. Consequently, this helps to trap DR dye molecules on the surface of CF and CA (i.e., physical adsorption), which supports our experimental results.
