WebMar 3, 2011 · A series of reduced and oxidized Pd/TiO2 catalysts were prepared and used for catalytic oxidation of formaldehyde (HCHO) at room temperature. The reduced catalysts were much more active than the oxidized ones. Nearly 100% HCHO conversion was achieved over the former while it was less than 18% over the latter. Sodium borohydride … WebMar 14, 2016 · Formaldehyde (HCHO) is one of the major pollutants in indoor air and long-term exposure to HCHO even at very low concentrations is harmful and may cause health problems including nasal tumors and skin irritation. Removal of HCHO is necessary to improve the quality of indoor air.
