Microstructure regulation of CsxWO3 nanoparticles by organic acid for improved transparent thermal insulation performance
Source abstract
Abstract
Abstract In order to further improve the transparent thermal insulation of Cs xWO3, controllable synthesis of CsxWO3 nanoparticles from cheap and environment-friendly Na 2WO4·2H2O and Cs2SO4 by solvothermal method was conducted using different organic acids as reducing agents. The reducibility and reduction mechanisms of citric acid, tartaric acid and oxalic acid were investigated. It has been confirmed that tartaric acid has the strongest reducibility, and could produce the most W5+ and oxygen vacancies in the Cs xWO3 products before heat-treatment. The CsxWO3 nanoparticles synthesized with oxalic acid after heat-treatment exhibited the best crystallinity and the visible light transmission was about 10% higher than that of tartaric acid and citric acid. It is significant for the low-cost production of CsxWO3 nanoparticles with higher transparent thermal insulation performance.
