[ 1 ] - Synthesis, Humidity Sensing, Photocatalytic and Antimicrobial Properties of Thin Film Nanoporous PbWO4-WO3 Nanocomposites

A humidity sensor thin film based on nanoporous PbWO4-WO3 composites has been prepared by spin coating technique with different weight ratio of PbWO4 (Pb) and WO3 (WO) (PWWO-01, PWWO-82, PWWO-64, PWWO-46, PWWO-28, PWWO-01) and their humidity sensing properties have also been investigated at different relative humidity (RH) in the range of 5% - 98% at room temperature with dc resistance. It is f...

[ 2 ] - Barium Oxide nanoparticles with robust catalytic, photocatalytic and humidity sensing properties

Barium Oxide(BaO) nanoparticles were synthesized by simple co-precipitation method and were investigated by the catalytic activity of synthesized barium oxide nanopaticles was enumerated by epoxidation of styrene. The reaction was carried out and the product was obtained at higher efficiency. Particularly, the photocatalytic efficiency was estimated by degradation of Rhodamine-B (RhB) dye using...
