The rational design of phosphated-zirconia leads to a highly active and selective catalyst for propanol dehydration to propene. At low loading, the phosphate species form a monolayer of pyrophosphate on zirconia, while they develop as 3D blocks of orthophosphate at high loading. The strong Brønsted acidic sites present on orthophosphate supported on zirconia are active for propanol dehydration.
