Co-Cu catalysts represent a promising possibility to synthesize higher alcohols. In this study, novel carbon-embedded Co-Cu catalysts have been prepared and were tested in an 8-fold parallel reactor system. Moreover, the influence of Mn as a dopant on the catalytic performance has been studied. It was shown that Mn reduced the selectivity for methane and favored the formation of olefins. In contrast to Cu-free catalysts, Cu-containing catalysts have an improved selectivity for alcohols.
