Microporous, silica‐supported metal oxides with a very narrow pore size distribution around 0.6 nm diameter, typical surface areas ranging from 350 to 700 m 2 /g, and loadings of well‐dispersed metal oxide (up to w = 10% of metal) result from the controlled calcination of silsesquioxane metal complexes. A versatile new methodology is envisioned that, in a combinatorial fashion, enables catalyst preparation with control over metal content and dispersity, together with adjustable Lewis and Brönsted acidity. In addition, the method is suitable for the preparation of bi and multifunctional catalysts containing different metals.
