Abstract
Formaldehyde(HCHO)as an indoor air pollutant released by new furniture and decorative materials is of great concern.Developing a self-cleaning device to remove HCHO is an ideal way to improve indoor air quality.In this study,a self-cleaning window with a multilayered structure constructed from fluorine-doped tin oxide/bismuth tungstate/resorcinol-formaldehyde resin(FTO/Bi2WO6/RF)has been fabricated,which is capable of degrading HCHO in natural indoor condition.The as-fabricated device could utilize the natural room light and promote the generation and transfer of the photocatalytic carriers in Bi2WO6,which subsequently delivers a good catalytic oxygen reduction efficiency in RF to produce hydrogen per-oxide(H2O2).The as-synthesized H2O2 could further split into hydroxyl radicals(·OH),then oxide the HCHO molecules in the air.The present study demonstrates a novel and efficient strategy to fabricate a transparent multifunctional window for self-cleaning indoor gaseous pollutants,the concept is of great importance to be expanded in a broad range of indoor furniture for in-house air pollution control.
