Crossover of liquid products from electrochemical CO2 reduction through gas diffusion electrode and anion exchange membrane
Andreas Züttel, Wen Luo, Jie Zhang
We reveal that a significant amount (>30%) of the liquid products from electrochemical CO2 reduction (CO2RR) in a flow reactor can cross the gas diffusion electrode (GDE) and anion exchange membrane (AEM). Crossover of volatile products through the GDE occ ...

Qian Wang, Jieping Zhu, Ruben Omar Torres Ochoa, Angel Renteria Gomez
In the presence of a catalytic amount of Pd(OAc)(2) and XantPhos, the three-component reaction of ynones, imines, and aryl iodides affords fully substituted alkylidene-furan-3(2H)-ones via a sequence of the Mannich reaction followed by chemo- and regiosele ...
AMER CHEMICAL SOC2020Designing Heterogeneous Catalysts for Renewable Catalysis Applications Using Metal Oxide Deposition
Jeremy Luterbacher, Yuan-Peng Du
Heterogeneous catalysis has long been a workhorse for the chemical industry and will likely play a key role in the emerging area of renewable chemistry. However, renewable molecule streams pose unique challenges for heterogeneous catalysis due to their hig ...
2019Thermal 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 ...
ELSEVIER SCIENCE BV2019Unraveling the complexity of oxygen reactions on Pt surfaces
Rainer Beck, Ana Gutiérrez González
Platinum (Pt) is a key material in automotive catalytic converters used to clean up the exhaust of the combustion engine. Pt particles in a ceramic matrix serve as an oxidation catalyst to eliminate toxic carbon monoxide (CO) and unburned hydrocarbons (CxH ...
2019Mechanistic implications of lanthanum-modification on gold-catalyzed formic acid decomposition under SCR-relevant conditions
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 ...
ELSEVIER SCIENCE BV2019In Situ Formation of Frustrated Lewis Pairs in a Water-Tolerant Metal-Organic Framework for the Transformation of CO2
Paul Joseph Dyson, Fatmah Ebrahim, Serhii Shyshkanov, Kyriakos Stylianou, Ngoc Tú Nguyên
Frustrated Lewis pairs (FLPs) consist of sterically hindered Lewis acids and Lewis bases, which provide high catalytic activity towards non-metal-mediated activation of "inert" small molecules, including CO2 among others. One critical issue of homogeneous ...
2019Oxidative cleavage of -O-4 bonds in lignin model compounds with a single-atom Co catalyst
Paul Joseph Dyson, Xile Hu, Zhaofu Fei, Antoine Philippe Van Muyden, Xiang Li, Lichen Bai, Zhangjun Huang, Xinjiang Cui, Sijie Liu
Single-atom catalysts are emerging as primary catalysts for many reactions due to their 100% utilization of active metal centers leading to high catalytic efficiencies. Herein, we report the use of a single-atom Co catalyst for the oxidative cleavage of th ...
2019Design of Stable Palladium-Based Zeolite Catalysts for Complete Methane Oxidation by Postsynthesis Zeolite Modification
Catalytic methane oxidation is used in exhaust gas aftertreatment to reduce methane emissions from lean burn natural gas vehicles as well as in stationary combustion processes. Pd/zeolite catalysts provide high activity for this reaction, but they deactiva ...
AMER CHEMICAL SOC2019Modulated 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 ...
