“…The plots' linearity was demonstrated, but they did not cross the origin, demonstrating that external mass transfer dominates the sorption process and acts as the rate-limiting process at the start of the adsorption of MB dye in the examined adsorbent Cs x H 3−x PW 12 O 40 /mZS. 76,83 The obtained CPW/mZS substances are evaluated with other prior catalysts published for the production of MB Table S1. † The comparative research is based on the reaction parameters as well as the percentage removal of MB.…”

“…In their work, the Cu-BTC was prepared by dissolving copper metal precursor in deionised water while BTC was dissolved in ethanol. The solution was then heated at 100 o C for 10 hours followed by washing with methanol for three days (Ediati et al, 2021).…”

The Cu-BTC (Copper -1,3,5-benzene tricarboxylate) is one of the representative metal organic frameworks (MOFs) that has shown outstanding performance for carbon dioxide (CO2) adsorption. However, its conventional synthesis duration is relatively long, and the process requires the addition of bulk amounts of organic solvents. Herein, an enhanced solvent-free synthesis strategy was demonstrated in this work for the Cu-BTC synthesis. For this enhanced method, Cu-BTC was synthesized in 3 hours by mechanically grinding the mixture of copper (Cu) metal precursor and BTC organic linker without using solvent. The as-synthesized Cu-BTC samples were analyzed using various characterization techniques to examine and confirm their properties. The thermal stability result revealed that the self-synthesized Cu-BTC could sustain high temperature up to 290 ℃. Among the samples synthesized at different mole ratios, the Cu-BTC sample with the Cu to BTC mole ratio of 1.5:1 showed the highest BET surface area and the most significant pore volume of 1044 m 2 g -1 and 0.62 cm 3 g -1 , respectively. Its CO2 adsorption capacity was comparable with those fabricated using the solvent-based method, i.e., 1.7 mmol g -1 at 30 ℃ and 1 bar. The results also showed that the synthesized Cu-BTC exhibited regenerative ability up to five adsorption-desorption cycles.

“…In RSM, optimization has an important role in generating the best condition that gives the highest response, wherein this case it is used to find out the optimum level of each independent parameter in the synthesis of HKUST-1. In the previous studies, HKUST-1 has been tried to adsorb some dyes in aqueous solution with a fairly high removal efficiency, such as congo red (>90%) [50], malachite green (83.4%), eosin yellow (94.9%) [51], and methylene blue (~95%) [52]. Hence, this study targeted the optimum HKUST-1 which could adsorb crystal violet dye in an aqueous solution with a removal efficiency close to or higher than previous studies.…”

Due to its excellency and versatility, many synthesis methods and conditions were developed to produce HKUST-1 ([Cu3(BTC)2(H2O)3]n). However, the diversity of HKUST-1 was actually generated both in terms of characteristics and morphologies. Hence, the consistency of HKUST-1 characteristics and morphologies needs to be maintained. The statistical analysis and optimization provide features to determine the best synthesis condition. Here, a room-temperature coordination modulation method was proposed to maintain the morphology of HKUST-1 while reducing energy consumption. In addition, response surface methodology (RSM) was used to demonstrate the statistical analysis and optimization of the synthesis of HKUST-1. The molar ratio of ligand to metal, reaction time, and acetic acid concentration were studied to determine their effects on HKUST-1. The optimum HKUST-1 was obtained by the synthesis with a molar ratio of ligand to metal of 0.4703 for 27.2 h using 5% v/v acetic acid concentration. The statistical analysis performed a good agreement with the experimental data and showed the significance of three desired parameters on HKUST-1. The optimum HKUST-1 had the adsorption capacity of 1005.22 mg/g with a removal efficiency of 92.31% towards CV dye. It could be reused up to 5 cycles with insignificant decrease in performance.
