Metal and metal oxide nanostructures can be prepared in much different morphology (nanowires, nanobelts, nanofibres etc.) which are known to exhibit better adjustable properties in many fields compared to their conventional counterparts. As part of ongoing research in the development of more selective and efficient (overall greener) oxidation catalysts, the present proposal is part of a wider research programme (including funding grants). This funded project aims at understanding and establishing morphology-activity relationships in oxidation catalysis. So far, promising results have been achieved which deserve to be further explored. For that matter INS is crucial to understand how the same catalytic system can yield different products just by changing the morphology of the catalyst. Results will contribute to establish a rational on how the mechanism works.
