Abstract:
The "nanomania" has reached catalysis science. Heterogeneous catalysis is considered the most successful nanotechnology. The scientific underpinning to that statement is questionable when the origin is investigated of the pronounced size effects in catalysis. It occurs that a new pardigm may emerge in catalysis if the present search for chemical complexity is replaced by the control of structural complexity of catalytic materials in a hierachical sequence of dimensions. Key scientific questions to achieve this are addressed. Several approaches to this goal are compared.
