Diverse synthesis of C2-linked functionalized molecules via molecular glue strategy with acetylene

Nature Communications, 2022
Although acetylene is an ideal two-carbon building block, very few catalytic methods can be applied to incorporate acetylene into fine chemicals. Here, the authors show photoredox-catalyzed syntheses of C2- linked molecules with gaseous acetylene under ...

Metal-Organic Framework Based Hydrogen-Bonding Nanotrap for Efficient Acetylene Storage and Separation.

Journal of the American Chemical Society, 2021
The removal of carbon dioxide (CO2) from acetylene (C2H2) is a critical industrial process for manufacturing high-purity C2H2. However, it remains challenging to address the tradeoff between adsorption capacity and selectivity, on account of their ...

Photo-thermo semi-hydrogenation of acetylene on Pd1/TiO2 single-atom catalyst

Nature Communications, 2022
Semi-hydrogenation of acetylene in excess ethylene is a key industrial process for ethylene purification. Supported Pd catalysts have attracted most attention due to their superior intrinsic activity but often suffer from low selectivity.

Reconstruction of Paleofire Emissions Over the Past Millennium From Measurements of Ice Core Acetylene

Geophysical Research Letters, 2020
Acetylene is a short‐lived trace gas produced during combustion of fossil fuels, biomass, and biofuels. Biomass burning is likely the only major source of acetylene in the preindustrial atmosphere, making ice core acetylene a powerful tool for ...

Selective visible-light photocatalysis of acetylene to ethylene using a cobalt molecular catalyst and water as a proton source

Nature Chemistry, 2022
The production of polymers from ethylene requires the ethylene feed to be sufficiently purified of acetylene contaminant. Accomplishing this task by thermally hydrogenating acetylene requires a high temperature, an external feed of H2 gas and noble-metal

Highly efficient ethylene production via electrocatalytic hydrogenation of acetylene under mild conditions

Nature Communications, 2021
Renewable energy-based electrocatalytic hydrogenation of acetylene to ethylene (E-HAE) under mild conditions is an attractive substitution to the conventional energy-intensive industrial process, but is challenging due to its low Faradaic efficiency ...

Molecular Fragmentation of Acetylene by VUV Double Photoionization

Proceedings, 2017
Acetylene is a simple molecule of interest for interstellar medium (ISM) and planetary atmospheres. The presence of C2H2 was detected by IR spectroscopic measurements. Acetylene was also found as a minor component in the atmosphere of gas giants like the
