Enhancing the electrochemical performance of hybrid supercapacitors with in-situ grown ultrasound-mediated heterostructure bi-metallic and dual-linker MOF nanoarchitecture by …

In the present technological era, energy storage devices like batteries and supercapacitors hold immense importance, and their hybrid variants have gained notable interest. The aim of this study was to develop a dual-linker MOF capable of selectively capturing cobalt and vanadium ions using two distinct organic ligands. The ultrasonication-assisted hydrothermal technique was demonstrated to be a resounding success in achieving the synthesis of the bimetallic and dual-linker metal-organic framework (MOF). The outcome of the electrochemical analysis demonstrated that the Co-V-capacitance MOF contributes to the battery-type process by diffusion control at 88.52 %, while 11.48 % of the process is capacitive-controlled, in an aqueous electrolyte (1 M KOH). Additionally, the upgraded Co-V-MOF electrode displayed an impressive specific capacity of 1711.1 F/g. The utilization of Co-V-MOF in the hybrid …

Improved properties and salt rejection of polysulfone membrane by incorporation of hydrophilic cobalt-doped ZnO nanoparticles

In this study, the nanoparticles (NPs) of ZnO and Co 2+ ions doped ZnO (doped ZnO) were incorporated into a matrix of polysulfone (PSf) membranes to enhance their surface properties prepared using a simple wet phase inversion technique. The hybrid PSf membranes were fabricated with 0.5 wt.% of ZnO and doped ZnO NPs. These membranes were characterized using XRD, TGA, FESEM-EDX, and salt rejection performance. The hydrophilicity of PSf membranes was improved by adding of ZnO and doped ZnO NPs which showed a decrease in contact angle values from 82 to 62 with an increased flux with water. Among the prepared membranes, doped ZnO NPs showed the highest salt rejection for both sodium chloride (NaCl) and sodium sulfate (Na 2 SO 4) compared to pure PSf and PSf with ZnO NPs which confirm the improvement contact angle and water permeability. Overall, the results of this study …

GO optimization strategies for improved capacity retention in transition metal oxides based ternary nanocomposites for high-performance supercapacitors

This work presents the optimization of GO in transition metal oxide based ternary nanocomposites (NiO/ZnO@(GO)x)for electrode materials in supercapacitor applications. The nanocomposites were synthesized using a straightforward sol-gel auto combustion route followed by sonication. It was observed from XRD analysis that crystallite sizes of NiO/ZnO@(GO)x nanocomposites vary between 49 and 24 nm. According to morphological study, the TEM images depict a hybrid nanoarchitecture with NiO/ZnO nanoparticles dispersed on graphene sheets. The maximum specific capacitance of 1833.9Fg−1 was obtained for NZG3 (NiO/ZnO with 6% GO).Furthermore, largest capacity retention of 98.7% was achieved for NZG3 after 6000 continuous cycles. NZ demonstrated 96% capacitance retention, for NZG1 it was 97.2% and capacity retention for NZG3, it was 98.7%. Therefore,optimized concentration of GO in NiO …

Synthesis and Evaluation of Novel Cu-Based Adsorbent-Containing Catalysts for CO2 Hydrogenation to Methanol and Value-Added Products

In this work, sequential incipient wetness impregnation method was used to synthesize Cu/Al2O3, Cu/Na2O/Al2O3 and Cu/CaO/Al2O3 catalysts in different compositions for CO2 conversion to value-added products. Synthesized catalysts were characterized using various analytical techniques and their performances for CO2 catalytic conversion were tested in a high-pressure packed bed reactor under reaction conditions of P = 60 bars, T = 300 oC, and H2/CO2 = 3. The obtained results revealed that the type of adsorbent had a significant impact on CO2 conversion, with CaO-containing catalyst being more efficient for methanol selectivity. Increased Cu content from 10 wt.% to 30 wt.% with fixed CaO content of 10 wt. % resulted in a small increase in CO2 conversion where the highest CO2 conversion of 16.44% and the highest methanol selectivity (17.75%) were obtained for catalyst containing 20 wt.% of copper …

Adsorption of Congo Red Dye Using Activated Carbon-Fe3O4 Composite

Activated Carbon-Fe3O4 composites were synthesized using co-precipitation method and used in batch experiments to adsorb Congo red dyes. The effect of adsorbent dosage, temperature and initial dye concentration was investigated. Increase in the adsorbent dosage resulted in the increase of dye adsorption capacity and the optimum dose was found to be 2 g/L. Increase in temperature had slightly negative impact on the adsorption which indicated the exhothermic nature of the adsorption process. Initial dye concentration also had significant impact on the adsorption process as the adsorption capacity of the AC- Fe3O4 adsorbents decreased with increase in dye concentrations. Finally, the obtained adsorption data were fitted to Langmuir adsorption isotherm and the maximum adsorption capacity of Activated Carbon-Fe3O4 adsorbent was found to be around 129.87 mg/g. Overall, the results suggested that synthesized AC- Fe3O4 composites exhibit significant potential to be used as an adsorbent for the removal of organic pollutants from aqueous solutions.

Enhancement of polysulfone ultrafiltration membrane with third generation poly (amido amine)-graphene oxide nanocomposite

In this era of rapid industrialization and urbanization, ultrafiltration is identified as a potential technology for wastewater reclamation to reduce the stress on renewable water resources. In this work, graphene oxide (GO) has been functionalized with poly (amido amine) (PAMAM) to produce GO-PAMAM nanocomposite that was embedded in polysulfone membrane matrix produced by phase inversion. The abundance of -OH and -NH2 groups on the synthesized nanocomposites resulted in improved hydrophilicity of the membrane and aided improving the membrane porosity and increased its pore radius. As a result, the membrane pure water permeation flux increased by 1300 % for the new membrane compared to pristine PSF membrane to reach a maximum of 124.5 LMH/bar while maintaining a high BSA rejection rate of 99 % with a flux recovery rate of 55 %. Although the flux recovery rate was low, the …

Poly (amido amine) dendrimer based membranes for wastewater treatment–A critical review

Membrane based wastewater treatment technologies in which polymeric membranes are most commonly used have been extensively applied in water/wastewater treatment to help address the issue of water shortage through water/wastewater reclamation and reuse. However, polymeric membranes due to their hydrophobic nature are subject damage caused by accumulation of organic/inorganic fouling during filtration processes, which results in a number of issues such as low water flux and low pollutant rejection. Several strategies have been considered to address these challenges and effectively improve the membrane performances. Alteration of membrane properties strategy using suitable nanofillers such us poly (amido amine) or PAMAM has been largely studied. Herein, research efforts regarding the synthesis and properties of PAMAM along with the synthesis of PAMAM multifunctional nanocomposites …

Graphene oxide/chitosan doped polysulfone membrane for the treatment of industrial wastewater

Rapid urbanization and industrialization have created tremendous stress on fresh water sources. Moreover, discharge of industrial wastewater has left public health and environment under high potential risks. In this paper, chitosan-functionalized graphene oxide (GO-CH) was synthesized and incorporated into polysulfone (Psf) ultrafiltration membranes. The concentration of the nanocomposite and the ratio of GO to CH in the nanocomposite were varied to produce different GO-CH doped polysulfone membranes. The effect of GO-CH addition on the morphology and membrane performance was studied through water contact angle, scanning electron microscopy, atomic force microscopy, porosity, pore size, and permeation measurements as well as rejection and antifouling tests, while produced GO-CH nanocomposite was characterized using FTIR and XRD analyses. The GO-CH/Psf membrane exhibited higher …
