Ceramic membrane based on TiO2-modified kaolinite as a low cost material for water filtration
Fatimah, Is; Sahroni, I.; Putra, H.P.; Nugraha, R.; Hasanah, U.A. (Elsevier, 2015)Ceramic membranes based on TiO2-kaolinite have been prepared using natural kaolinite, and their utilization in water filtration has been examined. This research aimed to evaluate the effect of TiO2 content on the physicochemical ... -
Effect of calcination temperature on the synthesis of ZrO2-pillared saponite to catalytic activity in menthol esterification
Fatimah, Is; Rubiyanto, D.; Kartika, N.C. (Department of Chemistry, Gadjah Mada University, 2016-06)The influence of calcination temperature on the synthesis of zirconia-pillared saponite (PILS) and on its catalytic activity in menthol esterification has been studied. Zirconia pillarization was conducted using zirconium ... -
Effect of Pt on catalytic activity of Al- and Zr-pillared smectite
Fatimah, Is; Yudha, S.P.; N.S., Happy Bunga; Ulya, R.; Rubiyanto, D. (Chemical Publishing Co., 2016)This study aimed to investigate the physico-chemical properties of Pt dispersed in Al and Zr pillared saponite and montmorillonite. The chemical and morphological characteristics of prepared materials were carried out by ... -
Effect of Zn content on the physicochemical characteristics and photoactivity of ZnO supported activated carbon
Fatimah, Is; Yudha, S.P; Sopiana, K.D.; Ratnasari, D.L. (OSPC, 2016-11-12)In the present work, synthesis of ZnO dispersed onto activated carbon (ZnO/AC) is reported.
