Keywords: Surface Plasmons, charging effect, DSSCs. The increase of Jsc is attributed to the enhanced dye light absorption in strength and spectral range due to the surface plasmon resonance of AgNPs in photo anode. The improvement is manifested chiefly as an increase in photocurrent density due to enhanced light harvesting by the silver nanoparticles (AgNPs). The plasmonic effect as observed by introducing in DSSC produces higher performance with short-circuitcurrent density (JSC) of 0.178 mAcm-2, open-circuit voltage (VOC) of 0.470 V, fill factor (FF) of0.554, yielding an efficiency (η) of 0.046%. Nanosized-photocatalysts with additional magnetic functionality have been studied extensively for many potential applications. The efficiency of betalain dye sensitized solar cell (0.009 %) increased to 0.046 % upon deployment of and to 0.024 % upon incorporation of nanoparticles. The performance of plasmon assisted dye sensitized solar cells capped with SiO2 and TiO2 was investigated. TiO2 is a widely studied metal oxide metal semiconductor that shows promising performance as a heterogeneous photocatalyst for energy and environmental applications such as organics pollutants photodegradation for air and water purification, photo-assisted removal of toxic. Metal nanoparticles are playing important role in photovoltaic and photocatalytic action of semiconductor nanostructures either through Fermi level shift or introducing localized surface plasmon effects. preparation sio2 tio2 composite and sio2 tio2 core shell Background. Transasctions of NAMP VOL4 (July, 2017).After analysing all the data, we found the best results at 4% (wt) concentration of nano core-shell particles aided in the PU coating system for multipurpose applications. Further these nano core-shell particles were aided in to the PU matrix and developed coatings were characterised by antimicrobial testing, surface wettability (water and oil), scratch-resistance, corrosion and erosion behaviour. The rod-like TiO 2 nanorodsSiO 2 core-shell nanoparticles were collected by centrifugal separation, washed with deionized water for 5 times and redispersed in ultrapure water for suspensions of 2 mg/mL TiO 2 nanorodsSiO 2 coreshell nanoparticles. Initially, prepared nanoparticles were investigated by TEM and XPS for the confirmation of core-shell structure. Reason behind this core-shell fabrication is to merge two different material properties in a single structure, in which silica (SiO 2) is used as a core material for improvement in mechanical properties and shell titania (TiO 2) is used to enhance the antimicrobial as well as hydrophobicity of the same coating surface. ![]() The photocatalytic degradation of Rhodamine B indicated that these composite particles with larger void space tended to have higher photoactivity. In this research, developed core-shell nanoparticles were incorporated in polyurethane (PU) at various concentration for the development of multifunctional surfaces on mild steel substrate. TEM observation showed that the composite particles had a unique rattle-type structure in which there existed void space between TiO(2) core and SiO(2) shell. Easy synthesis steps and low processing temperature is major achievement of this technique. These core-shell nanoparticles were synthesized by peptization process. This research work is devoted towards the development of highly efficient and cost-effective multifunctional nanocoating by silica-titania core-shell particles.
