The development of alternative cleaner, safer, and environmentally friendly technologies is one of the priorities in chemistry for sustainable future. Cascade catalysis, which combines various chemical steps without separating the intermediates, can play a vital role in improving the sustainability of chemical processes via process intensification with high economic benefit. At PNNL we focus on developing the low cost multi-functional mixed oxide catalyst for the conversion of the bioethanol to high value compounds via cascade catalysis. Particularly, we are interested in synthesizing high molecular weight oxygen containing compounds that can be used as fuel additives or intermediate for infrastructure compatible fuel as well as chemical commodity. Recently we have demonstrated a novel pathway to selectively convert ethanol to C<sub>5</sub>+ ketones such as 2-pentanone and 2- heptanone with minimal loss of carbon over a low cost multi-functional mixed oxide catalyst with &gt;70% yield to C<sub>5</sub>+ ketones. The detailed reaction mechanism and the role of mixed metal oxide in the ethanol conversion to C5+ ketones will be discussed in this presentation.
