Mesoporous silica nanoparticles (MSNs) were synthesized hydrothermally and modified with Co2+ and Zn2+. The as-prepared samples were denoted as MSN, Co-MSN(X), and Zn-MSN(X), where X is the Si/M molar ratio. In addition, co-modified MSN samples with both cations were also prepared and denoted as Co-Zn(Y)-MSN(X), where Y indicates the Zn2+ content in the range of […]
In this work, diisopropyl ether (DIPE) was produced through catalytic dehydration of isopropanol over zirconium phosphate-modified phosphate modified natural zeolite. The catalyst was prepared via the wet impregnation method. They were tested at 150 ˚C for 3 hours under a reflux system. The effect of zeolite-Zr(H2PO4)4 metal loading and zeolite-Zr without phosphate incorporation on dehydration […]
