Form an orderly Cu: Copper-based catalysts obtained by microwave-assisted morphosynthesis were correlated with the dehydrogenation of ethanol. The degree of reduction was monitored using time-resolved in situ XANES during TPR under H2. A semiquantitative estimation of the different chemical forms (Cu2+, Cu+, and/or Cu0) was obtained. The results suggest intrinsic particularities due to different morphologies at the active state in reduction kinetics.
