An efficient ultrasound assisted electrospinning synthesis of a biodegradable polymeric Ni-MOF supported by PVA- fibrous network as a novel CH4 adsorbent

In this study, Ni-MOF was synthesized using ultrasound irradiation under optimal conditions, which included a microwave power of 370 W, time duration of 20 min, and a temperature of 25 degrees C. The final Ni-MOF nanostructures were immobilized in a PVA fibrous polymeric network using electrospinning under optimal conditions (concentration: 8% wt; nozzle tip with flow rates of 0.10 mL/h; temperature: 25 degrees C and humidity: 22%; voltages: 20 kV; spinning distance: 12 cm). It has been characterized using elemental analysis, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Thermogravimetric analysis-derivative of thermogravimetric analysis (TG-DTG) and Scanning electron microscopy- energy dispersive X-ray analysis (SEM-EDS). The Barrett-Joyner-Halenda (BJH) technique confirmed the role of the substrate in increasing the surface area of the final products. The Ni-MOF/PVA fibrous network's final products were used as an adsorbent in the adsorption of CH4 gas.

Automated summary

In this study, Ni-MOF was synthesized using ultrasound irradiation and then immobilized in a PVA fibrous polymeric network using electrospinning. The Ni-MOF/PVA fibrous network showed potential as an adsorbent for CH4 gas adsorption.
