A porous CuO/MnO2 catalyst was synthesized by a gas release-assisted method. Due to the participation of gases (H2O, NH3, CO2) released from ammonia and carbonate, the porous CuO/MnO2 with high surface and abundant aperture structure was obtained. Benefitting from the large sp. surface area, high TOF and the proper at. ratio of Cu and Mn on the catalyst surface, 0.20CuO/MnO2 (where 0.20 acted as the molar ratio of copper to manganese species) has the best catalytic performance, which can completely remove formaldehyde at 130°C with 400 ppm HCHO concentration Under 10 times higher than the upper limit of indoor formaldehyde (World Health Organization), the formaldehyde conversion of the porous CuO/MnO2 catalyst remains above 97% at 25°C (the relative humidity RH ≤ 50%), which suggest it can almost completely remove the low concentration formaldehyde. The catalytic performance decays slowly within 6 h. Therefore, the porous CuO/MnO2 catalyst shows excellent low-concentration formaldehyde removal effect, long-term catalytic stability, suggesting it has a great potential for indoor formaldehyde removal under 0-50% relative humidity. This result not only provides an inexpensive, simple and efficient porous CuO/MnO2 material for formaldehyde removal indoor at room temperature but also provides a new strategy for the preparation of other porous material. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2SDS of cas: 20427-59-2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to the earth-abundant, inexpensive and low toxicity. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. SDS of cas: 20427-59-2
