Cover Feature: Selective Hydrogenation of Furfural Under Mild Conditions Over Single-Atom Pd1/α-MoC Catalyst (ChemSusChem 7/2025)

Abstract

The Cover Feature illustrates how the incorporation of Pd single-atom sites within a Pd₁/α-MoC catalyst alters the pathway of selective hydrogenation of furfural. Specifically, it facilitates the reaction under milder conditions and enhances its efficiency. The desert, rough road and bicycle symbolize the high reaction temperatures and low efficiency associated with the α-MoC catalyst. Conversely, the lush plant, highway and vehicle represent the mild conditions and high efficiency achieved with the Pd₁/α-MoC catalyst. Additionally, the models of the catalysts indicate that the Pd single atom effectively activates hydrogen molecules and selectively targets the C=O structure of furfural, enabling the reaction to proceed rapidly through a direct hydrogenation pathway, rather than via the MPV route.
