Dehydrogenation using dehydrogenation catalyst and polymer-porous solid composite membrane
, 1993 Light paraffinic hydrocarbons are catalytically dehydrogenated using a dehydrogenation catalyst and a polymer-porous solid composite membrane capable of separating hydrogen from the effluent of the dehydrogenation reaction.

Angewandte Chemie, EarlyView.Site‐specific self‐assembly of alkyl thiols on Au/TiO2 enables precise modulation of interfacial electron distribution and the local microenvironment through covalent Au‐thiolate interactions. This site‐specific molecular engineering synergistically promotes surface kinetics and charge separation, suppressing ·O2−‐driven overoxidation and thereby ...

Epitaxial Oxide Interfaces Create Poison‐Resistant CuO Sites for Environmental Catalysis
Angewandte Chemie, EarlyView.An epitaxially stabilized CuO overlayer on Ti1−xInxO2 creates electron‐poor, high‐symmetry Cu–O sites that activate interfacial lattice‐oxygen redox. This interface promotes NOx reduction through an Eley–Rideal pathway, diverts sulfate formation, and sustains CH3SH deep oxidation via a Mars–van Krevelen cycle, offering a route to poison‐resistant ...

Angewandte Chemie, EarlyView.Time‐resolved in situ x‐ray absorption spectroscopy and DFTB‐based molecular dynamics simulations identify direct hydrogen atom transfer from ethanol to lattice oxygen as the elementary step of laser‐driven reduction in NiCo2O4. While this transfer is facile, the subsequent release of lattice oxygen is entropy‐driven and becomes accessible only at ...

Angewandte Chemie, EarlyView.This work reports the design of a multifunctional MnOx support coupled with classic Rh catalytic centers for light‐driven dry reforming of methane. Benefiting from efficient photon‐to‐phonon conversion pathway and a dynamic OL‐OV cycle, the catalyst achieves high syngas production rates and light‐to‐chemical energy efficiency without external heating ...

Natural Sunlight IR‐Driven Highly Efficient Synthesis of Acetaldehyde From Bioethanol Over Cu/Fe2O3
Angewandte Chemie, EarlyView.This work reports a Cu/Fe2O3 catalyst for the conversion of bioethanol into valuable acetaldehyde and green hydrogen under both infrared (IR) light and natural sunlight. This IR‐driven system sets a new performance benchmark, with TON and initial TOF enhanced by at least one order of magnitude, enabled by a constructed IR photon‐to‐phonon channel and ...

STUDIES IN DEHYDROGENATION. PART V
, 1940 The syntheses and selenium dehydrogenation of tetrahydrophenanthrene-2 : 2- spiro cyclopentane and 9-methyltetrahydrophenanthrene-2 : 2-Spiro-cyclopentane have been described. The former on dehydrogenation gives chrysene and the latter forms 3-methyl- 1

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces
Angewandte Chemie, EarlyView.Hydroxyl‐functionalized dicarbaporphyrinoid polymers synthesized on Au(111) enable tunable oxygen‐mediated connectivity under UHV conditions. Thermal activation yields one‐dimensional hydroxyl‐terminated polymers that can selectively evolve into either covalently‐linked dibenzo‐p‐dioxane architectures through intermolecular C–O–C coupling or two‐fold ...
