dc.description.abstract | One of the efficient strategies to enhance light harvesting capability of metal oxides nanoparticles (NPs) is to deposit low band gap metal sulfides on them via pseudo-successive ionic layer adsorption and reaction (p-SILAR). Resultant oxide-sulfide nanocomposites have a variety of applications, however there is still a need to increase the deposition of metal sulfide in the form of quantum-dots (QDs). In this work, we have successfully enhanced the deposition of QDs on TiO2 NPs using a modernized H2S-treatment strategy. A rotary reactor was employed for H2S-treatment of TiO2 NPs, ensuing higher deposition of PbS (in TiO2-PbS) and CdS (in TiO2-CdS) via p-SILAR. Resultantly, dye degradation of Rhodamine B increased from 63% to 75% and 72%-84%, respectively. X-ray photoelectron spectroscopy revealed the efficacy of modernized H2S-treatment while intensive electrochemical characterization affirmed reduction in charge carrier transfer resistances due to superior deposition of PbS and CdS QDs on TiO2 NPs. | - |
