Cyclic Sulfoximine and Sulfonimidamide Derivatives by Copper‐Catalyzed Cross‐Coupling Reactions with Elemental Sulfur

Autor: Peng Wu, Jas S. Ward, Kari Rissanen, Carsten Bolm

Publikováno v: Advanced Synthesis & Catalysis. 365:522-526

Copper-catalyzed cross-coupling reactions of α-bromoaryl NH-sulfoximines with elemental sulfur lead to benzo[d][1,3,2]dithiazole-1-oxides, which represent a new class of three-dimensional heterocycles. The reactions proceed under mild conditions sho

Ligand assisted hydrogenation of levulinic acid on Pt(111) from first principles calculations

Autor: Lars Gell, Karoliina Honkala

Publikováno v: Catalysis Science & Technology. 12:1850-1858

In this study, we investigate the hydrogenation reaction of levulinic acid to 4-hydroxypentanoic acid on ligand-modified Pt(111) using DFT. Modifying nanoparticle surfaces with ligands can have beneficial effects on the desired reaction such as impro

Exploring CO2 hydrogenation to methanol at a CuZn–ZrO2 interface via DFT calculations

Autor: Lempelto, Aku, Gell, Lars, Kiljunen, Toni, Honkala, Karoliina

Multi-component heterogeneous catalysts are among the top candidates for converting greenhouse gases into valuable compounds. Combinations of Cu, Zn, and ZrO2 (CZZ) have emerged as promisingly efficient catalysts for CO2 hydrogenation to methanol. To

The role of polaronic states in the enhancement of CO oxidation by single-atom Pt/CeO2

Autor: Minttu Kauppinen, Nathan Daelman, Nuria Lopez, Karoliina Honkala

Single Atom Catalysts (SACs) have shown that the miniaturization of the active site implies new phenomena like dynamic charge transfer between isolated metal atoms and the oxide. To obtain direct proof of this character is challenging, as many experi

ReO as a Brønsted acidic modifier in glycerol hydrodeoxygenation : Computational insight into the balance between acid and metal catalysis

Autor: Ville Korpelin, Gokarneswar Sahoo, Rasmus Ikonen, Karoliina Honkala

A computational study for the competitive conversion of glycerol to 1,2-propanediol and 1,3-propanediol is presented, considering a two-step sequence of dehydration followed by hydrogenation. The elementary steps for dehydration, i.e., breaking of C�

Mechanistic Origins of the pH Dependency in Au-Catalyzed Glycerol Electro-oxidation: Insight from First-Principles Calculations

Autor: Anand M. Verma, Laura Laverdure, Marko M. Melander, Karoliina Honkala

Publikováno v: ACS Catalysis. 12:662-675

Electrocatalytic oxidation of glycerol (EOG) is an attractive approach to convert surplus glycerol to value-added products. Experiments have shown that EOG activity and selectivity depend not only on the electrocatalyst but also on the electrode pote

Electrocoagulation in water treatment:continuous versus batch processes and sludge utilization

Autor: Rajaniemi, K. (Kyösti)

This thesis deals with electrocoagulation (EC) in water treatment. The EC method has been in use with continuous development since the late 19th century, although there is a need for improved technical solutions. A review of the literature reveals de

Publikováno v: Angewandte Chemie International Edition. 60:3752-3758

Deciphering the molecular pictures of the multi-component and non-periodic organic-inorganic interlayer is a grand technical challenge. Here we show that the atomic arrangement of hybrid surface ligands on metal nanoparticles can be precisely quantif
