Abstract: Development of photoelectrodes for solar cells offers a strategy to achieve more efficient photon conversion systems. This work develops (TiO2)0.9 + ((ZnO/ZnS):x% rGO)0.1 photoelectrodes with rGO contents of 0.5, 1 and 2%, investigating the influence of […]
Abstract: In this study, a hybrid photocatalyst based on carbon nitride (g-C3N4) modified with the molecular cluster [Mo3S4Cl3(en)3]Cl was developed and evaluated for the visible-light-driven degradation of ciprofloxacin (CIP). The incorporation of the cluster introduced […]
Abstract: Silver silicate nanoparticles were synthesized via co-precipitation followed by microwave-assisted hydrothermal treatment for 0–64 min. X-ray diffraction confirmed that all samples were amorphous, while infrared spectroscopy, photoluminescence, and selected area electron diffraction revealed progressive […]
Abstract: Semiconductors have multiple applications in society, including photocatalysis and electrochemical sensors. Copper tungstate (CuWO4) particles can degrade organic compounds from water, but their deleterious effects on aquatic biota must be evaluated before their widespread […]
Abstract: Undoped and Ni-doped SnO were synthesized using a microwave-assisted hydrothermal method to analyze the influence of Ni-doped SnO nanostructures on CO detection. The scanning electron microscopy (SEM) analysis revealed a predominantly tetragonal SnO phase, […]
Abstract: The development of efficient and stable photocatalysts for environmental remediation remains a key challenge in the treatment of emerging pollutants. In this work, heterostructured photocatalysts based on KNb3O8 and Ag3PO4 were successfully synthesized via a simple […]
Abstract: In this work, we investigated how the electrical resistivity of LaNiO3 thin films deposited on SrLaAlO4 (100), LaAlO3 (100), and MgO (100) single-crystal substrates by the pulsed laser deposition (PLD) technique can be controlled by femtosecond laser […]
Abstract: The size- and shape-controlled synthesis of α-Fe2O3 nanoparticles was achieved via a solution combustion method using glucose, urea, and lemon juice as fuels. X-ray diffraction (XRD) confirmed the formation of α-Fe2O3 with minor γ-Fe2O3 phases, and crystallite sizes were calculated […]
Abstract: This study investigates the enhancement of photocatalytic efficiency in silver-modified sodium and hydrogen titanates. Silver nanoparticles, particularly along the (201) crystal plane of sodium titanate, improve electron mobility and reduce electron-hole recombination, leading to more effective degradation of organic pollutants under light exposure. In hydrogen titanate, silver further […]
