Incipient-wetness impregnation method

WebA 20 wt% of Co/TiOa was prepared by the incipient wetness impregnation. A designed amoimt of cobalt nitrate [Co (N03) 6H20] was dissolved in deionized water and then impregnated onto TiOj containing various ratios of rutileianatase obtained from above. The catalyst precursor was dried at 110°C for 12 h and calcined in air at 500°C for 4 h. WebFeb 1, 2024 · The KIL-2NH 2 and KIT-6NH 2 samples were loaded with curcumin by two different methods: deposition by incipient wetness impregnation (IW) and by solid-state reaction (SS). KIL-2NH 2 and KIT-6NH 2 and curcumin in weight ratio 1.0:0.5 were stirred in 1 ml ethanol until total evaporation of the solvent.
