A Prototype For Catalytic Removal Of Formaldehyde And Co In A Compact Air Cleaner Powered By Portable Electricity
MATERIALS ADVANCES(2020)
摘要
We proposed a prototype which can directly be powered by portable electricity for the catalytic removal of formaldehyde and CO. A compact air cleaner equipped with a conductive Ag-SnO2 catalyst and the corresponding reaction system were assembled, featuring a circuit to allow electric current to pass through the catalyst with Joule heating. The removal performances were superior to the thermal heating counterpart and the electricity was found to suppress CO poisoning, which was preliminarily attributed to the electron transport between Ag and SnO2.
