Dehydration of Isobutyl Alcohol on Cesium-Cobalt-Containing NASICON Catalysts

Double and triple cobalt-containing phosphates Cs1–2xCoxZr2(PO4)3 (x = 0.15, 0.25, 0.50) with NASICON structure obtained by the sol–gel method were characterized using XRD, BET, XPS, and UV spectroscopy. The major isobutyl alcohol conversion reaction on these phosphates is dehydration. The triple phosphates have higher catalytic activity than the double phosphates in accord with a correlation between the yield of olefins and the concentration of acid sites on the catalyst surface. © 2017, Springer Science+Business Media New York.
