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: 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 […]
Abstract: Since the mid-20th century, the interaction between light and inorganic semiconductors plays not only a key role in numerous fascinating phenomena but also provides the physical foundations for the development of many modern technologies […]
Abstract: NaNbO3 doped with Zn (0.00, 0.02, and 0.05 mmol) was synthesized by the microwave-assisted hydrothermal method. Photocatalytic and antibacterial activities were investigated. X-ray diffraction revealed the coexistence of two orthorhombic symmetries (P21ma and Pbma), with doping promoting a progressive […]
Abstract: This study investigates how pH influences the synthesis of Ag2SeO3 via a sonochemical route. Morphologies ranged from sheet- to rod-like particles, with slightly acidic conditions (pH 5) favoring smaller sheet-like structures. All samples exhibited high […]
In this paper, we synthesized NaNbO3 rods with Al(III) (0.00, 0.05 and 0.1 mmol) by the microwave-assisted hydrothermal method and evaluated the influence of doping on photocatalytic activity. The diffractograms reveal the coexistence of two orthorhombic space […]
Abstract: In this work, pure SnO2 nanoparticles (SnO2 NPs), doped and co-doped with Co2 + and Nb5+ (0.05 and 0.1 mol), were prepared using babassu mesocarp (Orbgnya Speciosa) extract as a natural polymerizing agent and microwave-assisted hydrothermal treatment. X-ray diffraction analysis (XRD) showed that the crystallinity of […]
Abstract: Carbon quantum dots (CQDs) have recently attracted attention across various fields due to their small size, high conductivity, fluorescence emission, low toxicity, and other desirable characteristics. In this study, highly fluorescent CQDs with an […]
Hydrogen-Mediated Photoelectrocatalysis with Nickel-Modified Poly(Heptazine Imides) Abstract: Polymeric carbon nitrides (C3N4) are photochemically active organic semiconductors that can be produced in a wide range of structural types. Here, a poly-(heptazine imide) containing nickel single atoms […]
The photocatalytic performance of Fe inserted in Nb2O5 obtained by microwave-assisted hydrothermal synthesis: Factorial design of experiments Abstract: Nb2O5 and Fe inserted Nb2O5 from 1 to 3 % were synthesized by the microwave-assisted hydrothermal method. […]
