Real-time Monitoring Reveals Dissolution/Redeposition Mechanism in Copper Nanocatalysts during the Initial Stages of the CO2 Reduction Reaction

Raffaella Buonsanti, Vasiliki Tileli, Dragos-Constantin Stoian, Tzu-Hsien Shen, Jan Vávra

Size, morphology, and surface sites of electrocatalysts have a major impact on their performance. Understanding how, when, and why these parameters change under operating conditions is of importance for designing stable, active, and selective catalysts. He ...

Iridium-catalyzed acid-assisted asymmetric hydrogenation of oximes to hydroxylamines

Nicolai Cramer

Asymmetric hydrogenations are among the most practical methods for the synthesis of chiral building blocks at industrial scale. The selective reduction of an oxime to the corresponding chiral hydroxylamine derivative remains a challenging variant because o ...

Modulated Excitation Raman Spectroscopy of V2O5/TiO2: Mechanistic Insights into the Selective Catalytic Reduction of NO with NH3

Davide Ferri, Oliver Kröcher, Adrian Marberger, Rob Jeremiah G. Nuguid

We report the increased level of mechanistic information that Raman spectroscopy can provide when combined with modulated excitation experimentation. A V2O5/TiO2 catalyst for the selective catalytic reduction (SCR) of NO, was subjected to periodic NH3 puls ...

Thermal activation and aging of a V2O3/WO3-TiO2 catalyst for the selective catalytic reduction of NO with NH3

Davide Ferri, Oliver Kröcher, Adrian Marberger, Rob Jeremiah G. Nuguid

Real-world vanadium-based catalysts for the selective catalytic reduction (SCR) of NO with NH3 are occasionally exposed to high temperatures, which can induce catalyst aging. In this work, a 2.0 wt% V2O5/WO3-TiO2 catalyst based on commercial WO3-TiO2 was l ...

Effect of SiO2 on co-impregnated V2O5/WO3/TiO2 catalysts for the selective catalytic reduction of NO with NH3

Davide Ferri, Oliver Kröcher, Adrian Marberger

Co-impregnation of vanadia and tungsta on titania produced highly active catalysts for the reduction of nitrogen oxides with ammonia but showed aging tendencies at temperatures around 600 degrees C. In order to preserve their low temperature activity after ...

Mechanistic implications of lanthanum-modification on gold-catalyzed formic acid decomposition under SCR-relevant conditions

Davide Ferri, Oliver Kröcher

The use of formate-based ammonia precursors as alternatives to urea in the selective catalytic reduction (SCR) process requires that formic acid released upon their thermolysis in the hot exhaust is rapidly decomposed to carbon dioxide. This work aims at t ...

Low-cost high-efficiency system for solar-driven conversion of CO2 to hydrocarbons

Ulf Anders Hagfeldt, Silver Hamill Turren Cruz

Conversion of carbon dioxide into hydrocarbons using solar energy is an attractive strategy for storing such a renewable source of energy into the form of chemical energy (a fuel). This can be achieved in a system coupling a photovoltaic (PV) cell to an el ...

Effectiveness of ammonia reduction on control of fine particle nitrate

Athanasios Nenes, Hairun Guo

In some regions, reducing aerosol ammonium nitrate (NH4NO3) concentrations may substantially improve air quality. This can be accomplished by reductions in precursor emissions, such as nitrogen oxides (NO) to lower nitric acid (HNO3) that partitions to the ...

Relationship between structures and activities of supported metal vanadates for the selective catalytic reduction of NO by NH3

Davide Ferri, Oliver Kröcher, Adrian Marberger

Transition and rare earth metal vanadates are potential active phases for the selective catalytic reduction (SCR) of nitric oxide by ammonia for exhaust gas emission control. In this work, various metal vanadates mixed with SiO2-WO3-TiO2 (TWS) were compare ...
