STABILISED ZINC OXIDE MATERIALS

Abstract: a silicon-modified zinc oxide material, wherein the silicon-modified zinc oxide material (i) has a bet surface area of at least 50 m/g, (ii) has a si:zn atomic ratio in the range of 0.001 to 0.5:1 and (iii) is in the form of a shaped unit selected from a pellet, extrudate or granule, or a wash-coat on a monolith support. the silicon-modified zinc oxide material has improved resistance to thermal sintering and may be used as a catalyst or sorbent material.
