Biomass can serve as a renewable source for both energy and carbon.
Acetone, n-butanol, and ethanol (ABE) fermentation broth as a biomass-derived source of fuels and chemicals has received a lot of attention for several decades. However, the crude fermentation broth contains low concentrations of oxygenates, limiting its practical applications.

Thus, it is important to develop a highly efficient water-resistant catalyst to directly and selectively convert crude aqueous oxygenate mixtures to value-added chemicals; water-immiscible ones (easy separation after reaction) are especially of great importance.
