“…Surface adsorbed oxygen was an important reactive oxygen species that affected the catalytic interfacial reaction at room temperature. 39 Hence, oxygen species and content are shown in Fig. 4b.…”

Room Temperature Catalysts for High Effective Degradation of Formaldehyde: Research Progresses and Challenges

“…Wang et al [158] showed that the efficiency of g-C 3 N 4 /Fe 2 O 3 oxidized HCHO (1 mg/m 3 HCHO) at different relative humidities followed the following order: 80 % > 70 % > 60 % > 50 % > 40 %. Zhang et al [159] investigated the degradation of HCHO over Ag 5 À LCOÀ I catalysts in the range of 0.64-2.90 vol % water content and found that the increase of humidity from 0.64 to 1.51 vol % had less effect on the removal of HCHO, whereas at a higher humidity of 2.90 vol %, the removal rate decreased to about 30 %, which may be due to the partial blockage of the active site by the excess water molecules caused by the partial blockage of active sites. Therefore, the hazard of high humidity is a common problem that needs to be addressed, and continuous efforts are needed to improve the water resistance of HCHO oxidizers.…”
