In this work, a photocatalytic process was carried out to recover gold (Au) from the simulated non-cyanide plating bath solution. Effects of semiconductor types (TiO2, WO3, Nb2O3, CeO2, and Bi2O3), initial pH solution (3–10), type complexing agents (Na2S2O3 Na2SO3) their concentrations (1–4 mM each) on Au recovery were explored. Among all employed semiconductors, TiO2 exhibited highest activity spent both in absence presence agents, which completely recovered within 15 min at 6.5. The...
An ultra-fast green synthesis of defective TiO 2 was conducted using a microwave-assisted method. Suitable defect contents and good porous properties play role in H production.
Zinc ferrites (ZnFe 2 O 4 ) nanoparticles were successfully prepared by the simple co-precipitation method. The effects of calcination temperature and amount surfactant on microstructure zinc ferrite products studied. characterized with X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) UV-Vis diffuse reflectance (DRS). XRD results confirmed formation a cubic spinel structure in all samples. SEM revealed that molecules play crucial...
A process of bio-methanol from biogas was studied by modifying kinetic model reaction’s Richardson and Paripatyadar comparing with laboratory data. Bio-methanol consists 2 steps: reforming reaction (at atmospheric pressure, temperature 500 - 750 °C) methanol synthesis constant pressure 40 bar, 140 280 °C). The each step individual simulated. Next both steps were integrated, then they simulated using ASPEN PLUS software. This work investigated the optimum operating condition predicted result...
