Synthesis of framework lithium zirconium molybdate phosphates and their catalytic properties in ethanol conversion reactions

Abstract

We have synthesized NASICON-type mixed phosphates with the general formula Li1 − xZr2P3 − xMoxO12, having different degrees of molybdenum substitution (x = 0, 0.1, 0.5, 1.0) and ranging in particle size from 50 to 300 nm. Their structure and morphology have been investigated using X-ray diffraction, scanning electron microscopy, and X-ray microanalysis. Analysis of the catalytic properties of the synthesized compounds in ethanol conversion reactions demonstrates that all of them exhibit catalytic activity for ethanol dehydration and dehydrogenation reactions and that the relationship between them depends on molybdenum content.
