The gold (Au) nanoplates were grown using seed mediated growth method on the substrate surface. This process consists of two-steps process; seeding and growth of the nanocrystals. The cation polymer namely poly-l-lysine (PLL) was deposited on the substrate to obtain high yield nanoplates before immersed into seed solution. The morphology image of Au nanoplates sample by FESEM shows the yield can be...
A facile method for in-situ dressing of multi-walled carbon nanotubes (MWNTs) with TiO2 nanoparticles was achieved using modified microwave technique. TiO2/MWCNT nanocatalyst was formed using titanium (IV) isopropoxide as the precursor in the presence of MWCNTs and constantly irradiated for 5 min. FE-SEM micrographs suggested that TiO2 nanoparticles were well attached on the outer sidewall of MWCNTs...
The main demanding aim for many researchers is to reduce the operating temperatures as well enhance the sensing performance of metal oxide based alcohol gas sensor. Increasing the surface to volume ratio by controlling the morphology is one of the possible methods to reduce operating temperatures of sensing nanomaterials. A microwave-assisted method has been used for effecting the formation of porous...
The effect of morphology of anatase TiO2 nanoparticles as photoanode in dye sensitized solar cells (DSSCs) has been investigated. Two types of TiO2 nanostructures, namely nanograss and nanospherical particles, used in this study have been prepared via liquid phase deposition (LPD) method. Electrochemical impedance spectroscopy (EIS) analysis of DSSCs device with a sandwich structure of ITO/TiO2/dye/electrolyte/...
