Dual Chemical Looping/Catalytic Process for Alkylation of Benzene With Ethane and Propane Yielding Ethylbenzene and Cumene Over Copper‐Containing Mordenite

open access: yesAngewandte Chemie, EarlyView.
We report a dual chemical looping/catalytic process coupling alkane dehydrogenation with aromatic alkylation over Cu‐mordenite, yielding up to 25% alkylated aromatics with >95% selectivity per cycle. In situ NMR, FTIR spectroscopy, and DFT show alkylation proceeds via a π‐bound Cu(I)–olefin intermediate and Brønsted acid sites.

Surface‐State–Regulated Product Distribution in Photothermal CO2 Hydrogenation Over MXene‐Based S‐Scheme Catalyst

open access: yesAngewandte Chemie, EarlyView.
This work establishes an MXene‐based S‐scheme heterojunction in which the cooperative interplay among metallic Ni, surface NiOx domains, and conductive Ti3C2Clx drives efficient charge separation and photothermal coupling. Progressive evolution of Ni surface states regulates the CH4/CH3OH product distribution by modulating interfacial energetics and ...
