Spray synthesis of nanomaterials for catalysis, a wind of change

Aluminosilicate zeolites are microporous crystals used as heterogeneous catalysts for petroleum transformation. Most part of time their porous networks present microporous restrictions of size below 1 nm, which limits their application to small molecules. Since their first industrial application 45 years ago, an alternative low-cost material presenting similar acidic properties, high surface area and larger pores is needed for using at the best the huge volume of heavy oil available made of ..
