The role of Rh on a substituted Al Anderson heteropolymolybdate: Thermal and hydrotreating catalytic behavior
CI Cabello, M Muñoz, IL Botto, E Payen - Thermochimica acta, 2006 - Elsevier
The influence of Rh heteroatom on the molybdenum reducibility in the Anderson-type
heteropolyoxomolybdate structure of formula (NH4) 3 [RhMo6O24H6]· 7H2O was
investigated by means of TPR technique. With comparative purposes, the thermal behavior
in non-reducing conditions was also carried out by means of TGA–DTA studies. The study
was performed by XRD, SEM, EDAX and FTIR–Raman techniques. Results were related to
those preliminary measurements over other XMo6 Anderson phases. Likewise, Rh (III)–Al …
