چکیده

This study considers the progress of our previous for hydrogen generation depends on highly ordered metal oxide/plasmonic materials. reports preparation Ag2O-Ag/Au Al2O3 template (Ag2O-Ag/Au/Al2O3) photocatalytic sewage water splitting and H2 gas production. Ni imprinting, followed by two-step anodization procedures, prepare template. Ag2O-Ag Au materials are prepared inside using electrochemical deposition sputter coating methods, respectively. The chemical structure is confirmed X-ray diffraction (XRD) photoelectron spectroscopy (XPS) analyses, in which all peaks characterized Ag2O, Ag, Au, confirmed. scanning electron microscope (SEM) images confirm a hexagonal with pore wide about 350 nm. accept same morphology after process, deposited template, pores still opened process. These open increase surface area then enhance optical electrical properties. For generated from water, produced photoelectrode achieved an incident to photon conversion efficiency (IPCE) 30%. Additionally, impact light wavelength intensity performance evaluated. Under increasing total power 25 75 mW.cm?2, current density (Jph) value goes up 8.9 9.5 mA.cm?2. study’s findings show promising results resolving issue energy remote areas turning wastewater into fuel.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Iron-doping-enhanced photoelectrochemical water splitting performance of nanostructured WO3: a combined experimental and theoretical study.

In this paper, we have studied Fe-doping of nanostructured tungsten trioxide (WO3) and its pronounced effect in promoting the photoelectrochemical (PEC) water splitting performance. Vertically aligned Fe-doped WO3 nanoflakes on fluorine-doped tin oxide (FTO) were synthesized via the hydrothermal method. An X-ray photoelectron spectroscopy (XPS) analysis confirmed the Fe(3+) substitution at the ...
