Nonthermal plasma activation of N2 can facilitate nitrogen adsorption on metal catalysts at low bulk temperatures and atmospheric pressure. We apply a plasma-assisted temperature-programmed reaction (plasma-TPRxn) for ammonia (NH3) synthesis using sequential exposure silica-supported catalyst to followed by thermal hydrogen treatment while ramping the temperature decouple from surface catalyzed hydrogenation steps. This approach eliminates effects phase reactions, thereby allowing direct...
Copper-exchanged chabazite (Cu-CHA) zeolites are the preferred catalysts for selective catalytic reduction of NOx with NH3. The low temperature (473 K) SCR mechanism proceeds through a redox cycle between mobile and ammonia-solvated Cu(I) Cu(II) complexes, as demonstrated by multiple experimental computational investigations. oxidation step requires two to migrate into same cha cage activate O2 form binuclear Cu(II)-di-oxo complex. Prior steady state transient kinetic experiments find that...

Cathodic corrosion of copper (Cu) has posed a significant challenge for over century, impeding various technological progresses such as electrochemical conversion CO2 (eCO2RR) into fuels and other value-added carbon products. In this study, employing combined Density Functional Theory (DFT) kinetic Monte Carlo (kMC) simulation approach, we delve the atomistic level mechanism driving phenomenon in Cu. Our hypothesis posits pivotal role alkaline hydrogen evolution reaction (HER) facilitating...
The electrochemical CO 2 reduction reaction (eCO RR) is one of the promising pathways which primarily leverages electrocatalysts such as copper (Cu) to facilitate conversion into higher value carbon products; C1 (e.g., CO, methane, formic acid, and methanol etc.) C2 ethylene, ethane, ethanol using renewable electricity. Cu only monometallic electrocatalyst able electrochemically transform hydrocarbons with appreciable activity selectivity. However, oxide-derived surfaces (OD-Cu) fall short...
