Room-temperature synthesis of TiO2 nanospheres and their solar driven photoelectrochemical hydrogen production


Article in International Journal of Energy Research 39(12) · August 2015 
DOI: 10.1002/er.3372
Highly monodisperse and crystalline anatase phase TiO2 nanospheres have been synthesized at room temperature from organometallic precursor, titanocene dichloride and sodium azide. The photoelectrochemical (PEC) water splitting performance on the TiO2 nanospheres was studied under illumination of AM 1.5G. The optimized photocurrent density and photoconversion efficiency of TiO2 NSPs were observed ~0.95 mA cm−2 at 1.23 V and 0.69%, respectively. The transient photocurrent response measurements on the TiO2 NSPs during repeated ON/OFF visible light illumination cycles at 1.23 V vs RHE show that both samples exhibited fast and reproducible photocurrent responses. The TiO2 NSPs show excellent catalytic stability, and significant dark current was not observed even at high potentials (2.0 V vs RHE).

An example of the application of the Strecker reaction in the synthesis of a new class of α-aminonitriles with benzimidazole and theophylline backbones has been developed. For the synthesis of these compounds, first 4-hydroxybenzaldehyde was reacted with 1,3- and 1,5-dibromides/epibromohydrin to produce the corresponding bromo-substituted aldehydes. Then, benzimidazole/theophylline was reacted with the latter to generate the related benzimidazolic/theophyllinic aldehydes.

This paper reports the preparation, characterization and catalytic application of a novel, magnetically separable catalyst consisting of tungstic acid supported on silica coated magnetic nanoparticles. To obtain this new catalyst system, first, (3-chloropropyl)triethoxysilane was reacted with silica coated magnetic nanoparticles to generate a 3-chloropropyl magnetic nanoparticle (3-CPMNP) substrate. Subsequently, the addition of sodium tungstate to 3-CPMNP resulted in the stabilization of tungstic acid species on the surface of the magnetic nanoparticles (MNP-TA). The synthesized catalyst was characterized using some different microscopic and spectroscopic techniques such as X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and FT-IR spectroscopy. The catalyst nanoparticles were obtained with near spherical morphology and an average size of ∼45 nm. The W content of the catalyst was determined by ICP analysis to be 82.5 ppm (82.5 mg L−1), which was equal to 8.25% w/w (0.45 mmol g−1). The catalyst was successfully used for the one-pot synthesis of spirooxindoles via the multicomponent reaction of isatins and dicarbonyl compounds in water, which was used as a green solvent. The results revealed that this new catalyst showed high catalytic activity in this protocol and that it can be reused at least 5 times without any change in its catalytic activity.

Surface modification of Fe3O4 nanoparticles with triethoxyethylcyanide groups was used for the immobilization of palladium nanoparticles to produce Fe3O4/Ethyl-CN/Pd. The catalyst was characterized using Fourier transform infrared, wavelength-dispersive X-ray, energy-dispersive X-ray and X-ray photoelectron spectroscopies, field-emission scanning electron and transmission electron microscopies, and X-ray diffraction, vibrating sample magnetometry and inductively coupled plasma analyses. In this fabrication, cyano groups played an important role as a capping agent. The catalytic behaviour of Fe3O4/Ethyl-CN/Pd nanoparticles was measured in the Suzuki cross-coupling reaction of various aryl halides (Ar[BOND]I, Ar[BOND]Br, Ar[BOND]Cl) with phenylboronic acid in aqueous phase at room temperature. Interestingly, the novel catalyst could be recovered in a facile manner from the reaction mixture by applying an external magnet device and recycled seven times without any significant loss in activity.
