Catalyst support materials, catalysts, methods of making such and uses thereof are described. Methods of making catalyst support material include combining anatase titania slurry with i) a low molecular weight form of silica; and ii) a source of Mo to form a TiO 2 —MoO 3 —SiO 2 mixture. Catalyst support material include from about 86% to about 94% weight anatase titanium dioxide; from about 0.1% to about 10% weight MoO 3 ; and from about 0.1% to about 10% weight SiO 2 . Low molecular weight forms of silica include forms of silica having a volume weighted median size of less than 4 nm and average molecular weight of less than 44,000, either individually or in a combination of two or more thereof. Catalyst include such catalyst support material with from about 0.1 to about 3% weight of V 2 O 5 and optionally from about 0.01% to about 2.5% weight P. |
