Reports from Ilie Murgulescu Institute of Physical Chemistry Provide New Insights into Zinc Compounds (Photocatalytic zinc oxide thin films obtained by surfactant assisted spray pyrolysis deposition)
By a News Reporter-Staff News Editor at Science Letter -- A new study on Zinc Compounds is now available. According to news reporting originating from Bucharest, Romania, by NewsRx correspondents, research stated, "Zinc oxide thin films were obtained by spray pyrolysis deposition using three surfactants with linear C-12 tails as soft templating agents: anionic sodium dodecylsulfate (SDS), cationic dodecyltrimethylammonium bromide (DTAB) and nonionic dodecanol (DD). The influence of the surfactants' type and concentration (above and below critical micelle concentration in the precursor system) on the thin film formation was investigated and was correlated with their photocatalytic efficiency in methylorange removal, under visible and UV iradiation."
Our news editors obtained a quote from the research from the Ilie Murgulescu Institute of Physical Chemistry, "The surfactants influence both the nucleation and growth stages, mainly through the Zn-surfactant interactions at the droplet border and/or on the micelles. In situ doping with Na+ (in SDS) improves the removal efficiency up to 19.88% under VIS irradiation, while the highest removal efficiencies in ZnO thin films obtained using DTAB and DD are 16.27% and 15.44%, respectively."
According to the news editors, the research concluded: "Under UV irradiation the highest efficiencies are 45.28% (SDS), 51.59% (DTAB) and 49.43% (DD)."
