A novel pillared layered clay having beryllium-containing pillars is produced by in a first step hydrolysing a hydrolysable compound of beryllium, for example a salt, and thereafter in a second step cation-exchanging a cation-exchangeable layered clay, for example a smectite, with the hydrolysate so- obtained. Pillared clays so produced are useful as catalysts, catalyst supports and adsorbents.
