“…In this reported material, there is a formation of different frameworks with different crystal phases which are interlinked to form a hybrid network. [23] Similarly in the present study, this CoO-AlPO 4 -4 material forms two different crystal phases which are interweaved together (Figure 2) and form a novel framework (Kankarlite).…”

Molecular sieves are reported with isomorphous substitution by various metal ions. In this article, interweaving between tetrahedral framework of AlPO4 and the octahedral framework of CoO to produce a novel framework material is investigated; it is named as “Kankarlite” (CoO–AlPO4‐4). It is characterized by X‐ray diffraction (XRD), Fourier transform infrared, Brunauer–Emmett–Teller (BET), UV‐Vis analysis, thermogravimetric analysis (TGA), temperature programmed desorption (TPD) analysis, and transmission electron microscopy. The special feature of the catalyst is that it has two frameworks that are interweaved together to form a novel framework, which is proved by XRD and the crystal structure is drawn by VESTA software. In CoO framework, oxygen has three coordinations, which is proved by crystal structure. An excess negative charge appears on oxygen, creating an oxyanion. The TPD is also proved the oxyanion formation. This oxyanion is responsible for decomposing CO2 with high selectivity and conversion. The AlPO4 framework's function is to create mesopores in the catalyst. The TGA and UV‐Vis analyses prove the interweaving between two frameworks. The BET analysis proves that the Kankarlite has a pore size of 4 nm.

“…The electrostatic interactions and surface charge characteristics of the CS/In 2 S 3 composite material are responsible for this observed trend. The material's surface may have a positive charge under more acidic (lower pH) conditions, encouraging electrostatic interaction with the negatively charged VB molecules 57 . The surface, however, becomes less positively charged as the pH www.nature.com/scientificreports/ rises, potentially lowering the adsorption capability.…”

A novel Chitosan/Indium sulfide (CS/In2S3) nanocomposite was created by co-precipitating Chitosan and InCl3 in solution, resulting in In2S3 agglomeration on the Chitosan matrix with a remarkable pore diameter of 170.384 Å, and characterized it for the physical and chemical properties. Under optimal conditions (pH = 7, time = 60 min, catalyst dosage = 0.24 g L−1, and dye concentration = 100 mg L-1), the synthesized nanocomposite demonstrated remarkable adsorption capabilities for Victoria Blue (VB), attaining a removal efficiency of 90.81%. The Sips adsorption isotherm best matched the adsorption process, which followed pseudo-second-order kinetics. With a rate constant of 6.357 × 10–3 g mg−1 min−1, the highest adsorption capacity (qm) was found to be 683.34 mg g−1. Statistical physics modeling (SPM) of the adsorption process revealed multi-interaction and multi-molecular adsorption of VB on the CS/In2S3 surface. The nanocomposite demonstrated improved stability and recyclability, indicating the possibility for low-cost, reusable wastewater dye removal adsorbents. These results have the potential to have practical applications in environmental remediation.

During this research project, response surface methodology (RSM) was used to optimise the adsorption of quinoline on modified orange peel biochar (MOPBC). The RSM was laid out using a design of experiments CCD (central composite design) with three experimental factors: initial concentration, temperature, and adsorbent dosage as the main variables. The F-value of the model was 97.16 with a p-value less than 0.0001. Indicated that the experimental data does not deviate from the model. The maximum quinoline removal of 98.01% when initial concentration dsorbent dosage and temperature were 50 mg/L, 0.02g and 40 °C.
