“…exhibited high crystallinity with five main diffraction peaks at 5.3°,7.6°, 16.7°, 26.6°and 30.7°, which are consistent with the reported XRD pattern of BiMOF. 38 As for BiMOF/CP, it had the same four peaks at 5.3°, 7.6°, 16.7°and 30.7°as found in BiMOF, as well as two peaks at 26.5°and 54.8°as found in pure CP, suggesting the successful growth of BiMOF on CP.…”

“…39 The O 1s spectrum shows a peak at the binding energy of 530.8 eV (Figure 3c), suggesting the O is coordinated with Bi. 38 As shown in Figure 3d, the C 1s spectrum can be divided into three main peaks. The peak at binding energy of 284.8 eV is assigned to C-C bond, and the peaks at 285.6 and 288.6 eV are attributed to the aryl carbon from the benzene ring and carboxylate carbon of carboxylic acid.…”

“…The BiMOF/CP was synthesized according to a reported method. 38 Typically, 0.3225 g Bi(NO 3 ) 3 •5H 2 O was dissolved in 10 mL dimethylformamide (DMF), and 0.166 g terephthalic acid was dissolved in 7.5 ml DMF with magnetic stirring. Then, the solution of Bi(NO 3 ) 3 •5H 2 O was slowly added dropwise into the solution of terephthalic acid under stirring.…”

In this work, a free-standing electrode composed of bismuth terephthalate metal-organic frameworks grown on carbon paper (BiMOF/CP) was successfully prepared by a facile one-pot hydrothermal method. Materials characterization revealed the formation of flower-like ultrathin nanosheets of BiMOF fully covering on the microfibers of carbon paper. The BiMOF/CP was applied in the electrochemical detection of Cd 2+ and Pb 2+ in water. The BiMOF/CP electrode exhibited superior sensing performance with a linear detection of Cd 2+ and Pb 2+ with low detection limits of 1.5 μg/L for Cd 2+ and 2.7 μg/L for Pb 2+ , respectively. The significantly enhanced sensing performance compared to bare carbon paper is attributed to the 3D hierarchical architecture of BiMOF and increased number of exposed surface sites, facilitating the adsorption of metals ions and electron transfer. The prepared novel materials will contribute to the development of cost-effective electrochemical sensors for heavy metal detection. Fig. 1 XRD spectrum of pure CP, BiMOF and BiMOF/CP. 78 | Eng.

“…28,30 Our previous studies have improved photocatalytic performance for bismuth terephthalate by changing the halide dopants, doped molar ratios of X À /Bi 3+ were optimized from 0.25 to 0.75 and found that molar ratio of each halide anion at 0.25 was an optimal composition concentration. [31][32][33] But a systematical study bismuth terephthalate is still needed to elucidate the effect of multiple halide dopants with the same molar ratios on bismuth terephthalate.…”

In this work Random Forest (RF) and Response surface methodology (RSM) were used to model and predict the efficiency of malachite green removal from aqueous solution by ultrasound-assisted adsorption onto the silver hydroxide nanoparticles loaded on activated carbon (AgOH-NPs-AC). The prepared nanoparticles were characterized by SEM, FTIR, XRD and TEM. The parameters such as pH, initial MG concentration, sonication time and adsorbent dosage involved in the adsorption process were set within the ranges 2.0-10, 4-20 mg L −1 , 2-6 min and 0.005-0.025 g, respectively. The performance of the RF and CCD models for the description of experimental data was evaluated in terms of the coefficient of determination (R 2 ), the root mean squared error (RMSE), mean absolute error (MAE) and absolute average deviation (AAD). The obtained results showed that the RF model outperformed in comparison to classical statistical model for modeling the process of dye adsorption. Desirability function approach (DFA) and Genetic algorithm (GA) combined central composite design (CCD) as global optimization technique were used for simultaneous optimization of effective factors. GA and DFA were revealed that 20 mg L −1 MG by 0.025 g AgOH-NPs-AC at pH = 8.0 and sonication time for 6 min with adsorption capacity 40.98 and 41.99 mg g −1 can be removed, respectively. The equilibrium adsorption data were analyzed by Langmuir Freundlich, Temkin and Dubinin-Radushkevich isotherm models. The best fit to the data was obtained from the Langmuir model.Meanwhile, the maximum adsorption capacity for MG by 0.01, 0.02 and 0.025 g of AgOH-NPs-AC was estimated 57.143, 42.735 and 40.980 mg g −1 , respectively.Analysis of experimental adsorption data to various kinetic models shows the applicability of the second-order equation model. The variable importance principle also shows that RF give maximum importance to sonication time for removal of MG.
