Abstract

The effect of water on cobalt speciation in the synthesis of Co²⁺/ZSMS catalysts is quantitatively studied by the combined use of macroscopic and local characterization techniques, TPR and X-ray absorption spectroscopies, respectively. The addition of a small quantity of water to cobalt acetate and zeolite during the preparation of Co²⁺/ZSM5 by solid-state reaction favors cobalt dispersion and migration into the zeolite. It also inhibits the formation of extraframework phases (Co₃O₄ particles, cobalt phyllosilicate). Dissociation of solid cobalt acetate upon contact with water is thought to be the driving force for enhanced cobalt migration into the zeolite.

<fC01 i1="01" l="ENG"><s0>The effect of water on cobalt speciation in the synthesis of Co<sup>2+</sup>
/ZSMS catalysts is quantitatively studied by the combined use of macroscopic and local characterization techniques, TPR and X-ray absorption spectroscopies, respectively. The addition of a small quantity of water to cobalt acetate and zeolite during the preparation of Co<sup>2+</sup>
/ZSM5 by solid-state reaction favors cobalt dispersion and migration into the zeolite. It also inhibits the formation of extraframework phases (Co<sub>3</sub>
O<sub>4</sub>
 particles, cobalt phyllosilicate). Dissociation of solid cobalt acetate upon contact with water is thought to be the driving force for enhanced cobalt migration into the zeolite.</s0>
