Nanostructured nickel oxide (NiO) photoelectrodes were fabricated with controlled morphology and texture using single‐step aerosol‐assisted chemical vapour deposition (AACVD). The durable one‐step film fabrication process resulted in highly crystalline columnar structure. Texture controlled films were also fabricated from granular to crystalline columnar morphology by controlling the deposition temperature. The thin film electrodes are highly reproducible and possess an optical bandgap of ~3.7 eV and exhibit cathodic photocurrent. (© 2014 WILEY‐VCH Verlag GmbH &Co. KGaA, Weinheim) 相似文献

In the process of fiber production from Zinc acetate and Polyvinylpyrrolidone using the electrospinning method, ZnO forms at temperature as low as 120 °C. The fibers were characterized using scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and ultraviolet–visible (UV–Vis) spectroscopy. Upon heating at 120 °C for 12 h some fibers shrink in diameter down to about 100 nm while others remain in the 400–900 nm range. Within the hybrid fibers, ZnO crystallizes in the wurtzite structure with a bang gap of 3.3 eV. The hybrid fibers exhibit the flexibility of polymer component and optical properties of ZnO phase, and promise to be very useful in various applications. 相似文献

A poly(4-vinylpyridine-co-aniline) (poly(4VP-co-Ani))-based solid-state ion sensor for cadmium (Cd) was developed. This was obtained from studies done on a number of selected monomers electropolymerized onto a poly(4vinylpyridine) (P4VP)-modified graphite pencil rod, surface characterizing them and then analyzing their performances as a Cd(II) ion sensor. Among them, the membrane of poly(4VP-co-Ani) at a mole ratio of 0.05:0.15 was found to be the best. The fabricated poly(4VP-co-Ani) solid-state electrode had a linear response of 1?×?10?6 to 1?×?10?2?M Cd2+, slope of 29.4?±?0.5 mV decade?1, detection limit of 7.94?×?10?7?M Cd2+, and response time of 15 s at pH 4.5–8.5 with excellent selectivity. The sensor was operationally stable within a period of 3 months. The proposed sensor was tested for determination of Cd2+ in environmental, plant, and pharmaceutical samples. The analyses were comparable to the standard atomic absorption spectrophotometric method. 相似文献

Optical and Photoacoustic Properties of Laser-Ablated Silver Nanoparticles in a Carbon Dots Solution

This study used the carbon dots solution for the laser ablation technique to fabricate silver nanoparticles. The ablation time range was from 5 min to 20 min. Analytical methods, including Fourier transform infrared spectroscopy (FTIR), UV-visible spectroscopy, transmission electron microscopy, and Raman spectroscopy were used to categorize the prepared samples. The UV-visible and z-scan techniques provided optical parameters such as linear and nonlinear refractive indices in the range of 1.56759 to 1.81288 and 7.3769 × 10−10 cm2 W−1 to 9.5269 × 10−10 cm2 W−1 and the nonlinear susceptibility was measured in the range of 5.46 × 10−8 to 6.97 × 10−8 esu. The thermal effusivity of prepared samples, which were measured using the photoacoustic technique, were in the range of 0.0941 W s1/2 cm−2 K−1 to 0.8491 W s1/2 cm−2 K−1. The interaction of the prepared sample with fluoride was investigated using a Raman spectrometer. Consequently, the intensity of the Raman signal decreased with the increasing concentration of fluoride, and the detection limit is about 0.1 ppm. 相似文献

This study aims at investigating the kinetics of calcium carbonate precipitation (scaling), that occurs in the form of vaterite, when treating seawater by direct contact membrane distillation (DCMD) operated at high concentration factors (from 4 to 6). Induction time measurements carried out by dynamic light scattering (DLS) allowed to identify the shifting between homogeneous and heterogeneous nucleation mechanisms as a function of supersaturation. CaCO3 interfacial energy, evaluated for concentrated seawater solutions as 45 mJ/m2, increased by 7% as a consequence of the inhibition effect of humic acid, and it was reduced to 32 mJ/m2 in correspondence of heterogeneous nucleation occurring on microporous polypropylene membranes. Gibbs free energy barrier to the formation of critical nuclei was predicted with good accuracy as a function of physico-chemical properties of the membrane (porosity: 0.70, contact angle: 115 ± 2°). 相似文献

Abstract Primaquine, Chloroquine, 8-aminoquinoline and 4-aminoquinalidine form molecular complexes with chloranil at pH 9. The composition and stability of these complexes have been studied spectrophotometrically. The results indicate that all complexes were of 1:1 type. The method of complexation was used to determine a ppm amount of the intended compounds in solution spectrophotometrically. 相似文献
