Summary: The study reveals that the bilayer beta(12) borophene, a new member of two-dimensional materials, exhibits significantly higher in-plane thermal conductivity compared to its monolayer counterpart. This abnormal enhancement is attributed to the suppressed phonon scattering possibility and elongation of phonon lifetime after forming the bilayer through interlayer covalent bonding. Furthermore, the dominated phonon branch to thermal conductivity was found to change to transverse acoustic phonons from out-of-plane flexural acoustic phonons in the monolayer borophene.

Summary: Dehydrogenation of glycerol for CO2 reduction can simultaneously produce lactic acid (LA) and formic acid (FA) products with high added value, greatly improving the atomic economy and the actual benefits. We report that Ru-MACHO (regR) as a catalyst can satisfy the requirements of parallel reaction at the same time. The designed experiment confirms that under the conditions of 200 degrees C and 48 h, 3 mg Ru-MACHO (regR) catalyst can obtain FA and LA yields of 40 % and 45 %, respectively. The possible reaction path of glycerol dehydrogenation for CO2 reduction is confirmed by the isotopic tracer technique and nuclear magnetic resonance analysis.

Summary: Selective breakage of the beta-O-4 bond in lignin is crucial for efficient conversion of lignocellulose. In this study, a novel polyoxometalate (POM) catalyst, H6V2Mo18O62, was developed through the atom-by-atom replacement strategy, which exhibited significantly enhanced activity compared to the original H6P2Mo18O62. By using a deep eutectic solvent as a solidifying agent, BetH(5)V(2)Mo(18) was obtained, which demonstrated controlled acidic/redox ability and thermosensitive ability for mass-transferring. This trinitarian catalyst enabled the full utilization of lignocellulose via temperature-programmed treatment.
