Zinc oxide (ZnO) nanoparticles were synthesized by the hydrothermal method and incorporated with diverse amounts of nonmetal element sulfur (0.5, 0.8, 1.1, 1.3, 2.1, 2.5, 3.2, 6.8, 7.8, 11.9, 12.3, 17.4 wt %). The physicochemical properties all investigated X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy, transmission N2 adsorption/desorption isotherms, as well Fourier transform infrared, diffuse reflectance, ultraviolet–visible absorption, photoluminescence...
Mesoporous sulfur-doped graphitic carbon nitride (MCNS) materials were successfully synthesized using thiourea as a low-cost precursor and SiO2 gel solution template through simple thermal condensation method. The effects of three synthesis key factors, namely, the reaction temperature, time, weight ratio SiO2/thiourea, also their interactions on removal rate methyl orange (MO) investigated response surface methodology, samples subjected to several characterization techniques. Results showed...
A one-step, simple and low-cost strategy was successfully used to produce novel NiS<sub>2</sub>/S-doped g-C<sub>3</sub>N<sub>4</sub>photocatalysts.
Three simultaneous strategies were successfully combined, for the first time, in one material including sulfur doping, creating a mesoporous structure, and deposition of Cu element as low-cost non-noble metal to modify internal external surfaces carbon nitride framework. For this purpose, sulfur-doped graphitic (MCNS) materials synthesized from thiourea low cost precursor SiO2 gel solution template through thermal condensation method. A series copper deposited MCNS (Cu/MCNS) with nominal...
In this work, an Fe-supported cagelike mesoporous silica type SBA-16 catalyst (Fe/SBA-16) was successfully synthesized using iron nitrate as the precursor through a simple impregnation method. Results of X-ray diffraction, N2 adsorption–desorption, transmission electron microscopy, and elemental mapping analysis showed that structure support retained during preparation nanoparticles were dispersed on surface. Moreover, ultraviolet–visible photoelectron spectroscopic studies revealed...
Abstract It is critical to facilitate surface interaction for liquid–solid two‐phase photocatalytic reactions. This study demonstrates more advanced, efficient, and rich molecular‐level active sites extend the performance of carbon nitride (CN). To achieve this, semi‐isolated vanadium dioxide obtained by controlling growth non‐crystalline VO 2 anchored into sixfold cavities CN lattice. As a proof‐of‐concept, experimental computational results solidly corroborate that this atomic‐level design...
Abstract In this research, the ultrasound (US) technique was applied as a facile synthesis method for preparing black TiO 2 ‐g‐C 3 N 4 type II heterojunction, coupled with Schottky junction MOF (ZIF‐67)‐derived x wt% Co S /nitrogen‐doped carbon (NC) ( = 3, 10, and 15) hollow nanobox (HNB) morphology, smart nanoheteroarchitecture (NHA) photocatalyst to enhance visible‐light photocatalytic activity. Additionally, solvothermal route employed fabricate /NC cubic nanoboxes (CHNBs) before...
Carbon quantum dots (CQDs) hold significant promise for wastewater treatment because of their remarkable attributes, including robust stability, outstanding biocompatibility, minimal toxicity, superior water dispersibility, cost-effective production, and exceptional photo-stability. In this study, CQDs were synthesized using microplasma tested the degradation rhodamine B (RhB) (5 mg/L) under different conditions, with a Solar simulator UVA illumination. Specifically, graphitic carbon nitride...
Making heterojunctions between semiamorphous carbon nitride (CN) and other well-matched semiconductors (or even insulators) can solve many photocatalytic problems such as the recombination of charge carriers. However, researchers encounter intrinsic including lack detailed information on contact boundaries in their heterojunctions, particularly amorphous/amorphous interface. In addition, roles mechanisms are still obscure. This study synthesized a novel CN/SiO2/WO3 photocatalyst having two...
Abstract The current lack of stable, scalable, and efficient coating technology dramatically limits the exploitation solar‐driven graphitic carbon nitride (CN) photocatalysts. Herein, a unique, efficient, scalable method is reported to immobilize CN powder on various substrates ranging from Fluorine tin oxide (FTO), glass, Plexiglas, Al foil, Ti Granite stone, even wood. film shows an outstanding thickness 212 µm, which highest value ever reported. formation process ascribed free radical...
