Bioethanol and furanics are currently prevailing additives to fossil-based transportation fuels. With the objective to lift the longstanding limitations of these biofuel additives, this work reports for the first time the synthesis of 2-ethoxy-2-methyltetrahydrofuran (2-EO-2-MTHF) as a co-upgraded fuel by reacting ethanol with 2-methylfuran (2-MF). The formation of 2-EO-2-MTHF is achieved through ethanol ethoxylation of 2-MF, enabled by a reverse Ni(OH)/Ni catalyst under hydrogen pressure.

In this context, strategies for rational catalyst design are critical to obtain high selectivity for the desired products in biomass upgrading. The Sabatier principle provides a conceptual framework for designing optimal catalysts by following the volcanic relationship between catalyst activity for a reaction and the binding strength of a substrate on a catalyst.

This work reports a targeted activation of C-O-C of furfural alcohol (FA) to produce pentanediols (PeDs) over MnO-modified Cu. Infrared spectroscopy revealed the strong interaction of the furan ring and C-O-C of FA with the catalyst surface in a preferred flat adsorption configuration, thus facilitating the activation and cleavage of C-O-C to form PeDs.

Six distinct L-subshell X-rays, Lι, Lα, Lβ, Lβ, Lγ and Lγ, are observed. Compared to the atomic data, the energy of the experimental X ray shifts to the higher energy side.

Integrated management of oomycete diseases is becoming more challenging, and plant derivatives represent effective alternatives to synthetic chemicals as novel crop protection solutions. Biologically active secondary metabolites are rapidly synthesized and released by plants in response to biotic stress caused by herbivores or insects, as well as pathogens.

Expensive cellulase and complex detoxification procedures increase the cost of biomass lactic acid fermentation. Therefore, it is of great significance to develop a robust method to ferment lactic acid using biomass by avoiding cellulase and detoxification. This study demonstrates the advantage of combining mechanocatalytic PO pre-treatment and strain domestication.
