“…Another new routes for synthesizing the PANI nano-composites, hollow Fe 3 O 4 -PANI spheres with uniform cavity size and shell thickness suggested [21], PANI nanotubes containing Fe 3 O 4 nanoparticles synthesized under ultrasonic irradiation [22] where the Fe 3 O 4 nano-particles embedded in PANI nanotubes. The PANI nanocomposites focus not only on ferrites but they extended to other materials such as titanium dioxide, zinc oxide, manganese oxide, vanadium pentaoxide, clinoptilolite, nafion, carbon nanotubes and silicon [23][24][25][26][27][28][29][30].…”

“…The physical and chemical behavior of TiO 2 nanoparticles must be understood to design and control various processing parameters [1][2][3][4][5]. The majority of the research on the synthesis of TiO 2 photocatalysts is focused on conventional wet syntheses such as precipitation, impregnation, and sol-gel techniques.…”

Previous studies have been shown that synthesis of titania (TiO 2 ) crystalline phase purity could be effectively controlled by the oxygen concentration through titanium tetra-isopropoxide (TTIP) via premixed flame from a Bunsen burner. In this study, a modified Hencken burner was used to synthesize smaller TiO 2 nanoparticles via short diffusion flames. The frequency of collisions among particles would decrease and reduce TiO 2 nanoparticle size in a short diffusion flame height. The crystalline structure of the synthesized nanoparticles was characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), Barrett-Joyner-Halenda (BJH) and Brunauer-Emmett-Teller (BET) measurements. The characteristic properties of TiO 2 nanoparticles synthesized from a modified Hencken burner were compared with the results from a Bunsen burner and commercial TiO 2 (Degussa P25). The results showed that the average particle size of 6.63 nm from BET method was produced by a modified Hencken burner which was smaller than the TiO 2 in a Bunsen burner and commercial TiO 2 . Moreover, the rutile content of TiO 2 nanoparticles increased as the particle collecting height increased. Also, the size of TiO 2 nanoparticles was highly dependent on the TTIP loading and the collecting height in the flame.

“…Herein, the enhanced photovoltaic performance and J SC are related to the highly ordered NRs morphology, high dye loading and improved light harvesting efficiency through the high surface area of the fi lm. Besides these, the unique ordered morphology of the NRs might retard the recombination rate and contribute to longer electron lifetimes [48], resulting in the increased V OC and FF of the device. The IPCE of DSSCs fabricated with highly ordered tetragonal TiO 2 NRs and distorted hexagonal TiO 2 NRs photoanodes have shown broad absorption edge of visible spectrum from 400-800 nm.…”

The fabrication of semiconducting materials with controlled size and morphology is an exciting, rapidly expanding research area for realizing the peculiar physical/chemical properties and the possible practical applications at the nano-to-microscale. Also, the technological applications for nanocomposites of organic/inorganic materials are of great interest in scientifi c research due to their unique and tunable electronic and optical properties. The semiconducting materials at nanoscale are widely used for the manufacturing of various electronic, electrical and photovoltaic devices owing to their unique band structure, optical properties, good charge mobility and ability to absorb photons from light. Among various photovoltaic devices, a regenerative photoelctrochemical solar cell called DSSC is a promising photovoltaic device for achieving reasonably high conversion effi ciency as compared to the conventional silicon solar cells. Various metal oxide semiconducting nanomaterials such as ZnO, TiO 2 , SnO 2 , Nb 2 O 5 and CeO 2 -based thin fi lm electrodes and their nanocomposites have also shown comparably good conversion effi ciency of DSSC due to their good optical and electronic properties. These semiconducting metal oxides possess high surface area which is essential for acquiring a high amount of dye
