Facile synthesis of g-CN@Sulfated titania nanocomposites with enhancement visible-light degradation of dyes and antibiotics: Mechanistic and DFT studies.

The photocatalytic efficiency of TiO has been opposed by the fast recombination speed of photogenerated carriers. Here, g-CN -modified sulfate-built-in TiO quantum dots (ST-QDs) were successfully created using a simple ultrasonication-thermal procedure. g-CN-enrapped ST QDs with a 10 nm size were revealed by the characterization results.

Boosting ciprofloxacin and indigo carmine dye photodegradation using S-scheme plate-like BiOI@sulfated TiO heterojunctions: An understanding of the performance, the degradation route, and DFT computation.

Sustainable BiOI/sulfated TiO nanocomposites were created for the present study utilizing the environmentally friendly dispersion-ultrasonication technique. Then, their ability to degrade the medication ciprofloxacin (CIP) and indigo carmine coloring (IC) in aquatic water was evaluated. The optimized catalyst 10%BiOI/ST, denoted as 10BOST together with 5BOST, is subjected to thorough characterization together with that of sulfate-free TiO (10BOT) to assess their physiochemical, morphological, textural, structural, and elemental composition properties.

Rapid reduction of nitroarenes photocatalyzed by an innovative MnO/α-AgWO nanoparticles.

A novel photocatalyst based on the design of P-N heterojunction between hollow spherical MnO and nanorods shape of α-AgWO is synthesized using a sonication-deposition-precipitation route.

The MnO/α-AgWO(60%) catalyst exhibited an excellent photo-reduction activity comprised of 0.

Dispersed AgO/Ag on CNT-Graphene Composite: An Implication for Magnificent Photoreduction and Energy Storage Applications.

A simple hydrothermal route assisted by a triblock copolymer was used to synthesize AgO/Ag nanoparticles on a robotic support consists of functionalized MWCNTs and graphene composite (AgO/Ag/CNT-graphene). The composites together with the individual analog of Ag/CNT and Ag/graphene were characterized by means of XRD, TEM-SAED, N sorptiometry, Raman, FTIR, UV-Vis, and photoluminescence spectroscopy. These nanomaterials were then tested for the catalytic reduction of 4-nitrophenol (4-NP) to the technologically beneficial 4-aminophenol (4-AP).

Nitrogen Graphene: A New and Exciting Generation of Visible Light Driven Photocatalyst and Energy Storage Application.

The synthesis of nitrogen, boron, and nitrogen-boron-codoped graphenes was attained via mixing solutions of GO with urea, boric acid, and a mixture of both, respectively, followed by drying in vacuum and annealing at 900 °C for 10 h. These materials were thoroughly characterized employing XRD, TEM, FTIR, Raman, UV-vis, XPS, IPCE%, and electrical conductivity measurements. The nitrogen-doped graphene (NG) showed an excellent supercapacitor performance with a higher specific capacitance (388 F·g at 1 A·g), superior stability, and a higher power density of 0.

SnO₂(β-Bi₂O₃)/Bi₂Sn₂O₇ nanohybrids doped with Pt and Pd nanoparticles: applications in visible light photocatalysis, electrical conductivity and dye-sensitized solar cells.

Bi2O3-SnO2 nanocomposites formed at a nominal molar ratio of 3 : 1 and loaded with Pd/Pt nanoparticles synthesized by a sol gel-hydrothermal method with the aid of a template were thoroughly characterized by X-ray diffraction, TEM-EDX, N2 sorptiometry, diffuse reflectance UV-Vis, FTIR, photoluminescence and electrical conductivity. It has been shown that Pd and Pt stimulate the existence of β-Bi2O3 and SnO2, respectively together with the key component Bi2Sn2O7. The photocatalytic results indicate that Pd/β-Bi2O3-Bi2Sn2O7 revealed a remarkable performance for the degradation of methylene blue (MB) dye as compared to the Pt/SnO2-Bi2Sn2O7 and Bi2O3-SnO2 samples in both the UV and visible regions.

Fabrication and characterization of bimetallic Pt-Au nanowires supported on FSM-16 and their catalytic activities toward water-gas shift reaction.

A facile, previously unexplored, method to synthesize bimetallic Pt-Au nanowires (20nm diameter×120-170nm long) on mesoporous FSM-16 (2.7nm) was fabricated by co-impregnation of H(2)PtCl(6) with HAuCl(4) followed by evacuation at 300K and finally exposure to the CO/H(2)O gas mixture (60:5Torr) at 323K for 1.0h.

Acid dye removal: comparison of surfactant-modified mesoporous FSM-16 with activated carbon derived from rice husk.

Cetyltrimethylammonium bromide (CTAB)-modified mesoporous molecular sieve FSM-16, prepared by a hydrothermal process (373 K, 3 days), was tested as an adsorbent for acid dye (acid yellow, AY, and acid blue, AB) removal in comparison with as-prepared FSM-16 and activated carbon (AC) derived from rice husk (50 vol% H3PO4, 773 K, 2.5 h). The adsorption isotherms, sorption kinetics, and pH effects upon acid dyes sorption on the adsorbents were thoroughly investigated.

Structural and acidic characteristics of Cu-Ni-modified acid-leached mordenites.

Two series of dealuminated Na-mordenite zeolites (DML and DMH) were impregnated, in comparison with the parent nondealuminated NaMSP, in aqueous nitrate solutions of Cu and Ni to achieve varying loadings for both of the cations. These samples were characterized by N(2) adsorption, XRD, DSC of ammonia desorption, ammonia volumetric sorption, IR of ammonia adsorption, and FTIR-photoacoustic (FTIR-PAS) techniques. The FTIR-PAS spectrum of CuNi-loaded NaMSP shows a band at 935 cm(-1) ascribed to O(3)Siz.
