High-purity hydrogen production from dehydrogenation of methylcyclohexane catalyzed by zeolite-encapsulated subnanometer platinum-iron clusters [PDF]
Nature CommunicationsLiquid organic hydrogen carriers (LOHCs) are considered promising carriers for large-scale H2 storage and transportation, among which the toluene-methylcyclohexane cycle has attracted great attention from industry and academia because of the low cost and

Ultrafast solvent-modulated roaming mechanism in bromoform revealed by femtosecond X-ray solution scattering [PDF]
Nature CommunicationsRoaming-mediated isomerization is a universal reaction mechanism in photochemistry, yet solvent-dependent pathways of roaming intermediates remain poorly understood, particularly for environmentally relevant halogen compounds involved in ozone depletion.

Self-assembled Helical Tetramer Stack of Terrylene Bisimide in Solution and Crystalline State. [PDF]
Angew Chem Int Ed EnglA TBI with sterically demanding imide substituents self‐assembles in solution into a defined helical tetramer π‐stack. Both the monomer and the tetramer can form complexes with polycyclic aromatic guest molecules, resulting in the formation of tri‐ or hexalayer in solution and in the crystalline solid state.

International Journal of Hydrogen Energy, 2020 For a liquid organic hydride system used for a hydrogen carrier, methylcyclohexane (MCH)–toluene cycle is promising. In this cycle, dehydrogenation of MCH is an endothermic reaction and a key step. We have conducted dehydrogenation of MCH over Pt/anatase-

Photochemical Cyclization of Tertiary Buta-2,3-dienamides to β-Lactams Upon Triplet Energy Transfer. [PDF]
Angew Chem Int Ed EnglEnergy transfer is the key to the successful photocyclization of the title compounds to 3,4‐disubstituted 2‐azetidinones. If the substituent at the nitrogen atom is primary (R2 = H), trans products are formed exclusively. The triplet state of xanthen‐9‐one (XT) was found to be quenched by an allene amide (R, R2 = H, R1 = Bn, and R3 = Ph) with a ...
