An In Situ Surface-Enhanced Infrared Absorption Spectroscopy Study of Electrochemical CO2 Reduction: Selectivity Dependence on Surface C-Bound and O-Bound Reaction Intermediates

Nicola Marzari, Oliviero Andreussi, Francesco Nattino

The CO2 electroreduction reaction (CO2RR) is a promising avenue to convert greenhouse gases into high-value fuels and chemicals, in addition to being an attractive method for storing intermittent renewable energy. Although polycrystalline Cu surfaces have ...

Shape and size control of colloidal CdSe nanocrystals in the presence of carboxylate and alkylamine ligands

Xiaopeng Huang

In this thesis, we focus on investigating the shape and size evolution of colloidal CdSe nanomaterials in the presence of carboxylate and alkylamine surface ligands. By elaborating the combination of carboxylates and alkylamines with different hydrocarbon ...

Reversible Segregation of Ni in LaFe0.8Ni0.2O3 +/-delta During Coke Removal

Oliver Kröcher, Davide Ferri, Patrick Simon Steiger

The deactivation of supported nickel catalysts by coking is an important technological subject for many chemical processes, especially when high concentrations of unsaturated hydrocarbons are present in the feed gas. Here, the reversible segregation of Ni ...

Room temperature C(sp(2))-H oxidative chlorination via photoredox catalysis

Xile Hu, Lei Zhang

Photoredox catalysis has been developed to achieve oxidative C-H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant. The reactions occur at room temperature and exhibit exclusive selectivity for C(sp(2))-H bonds ...

Nitrogen, Phosphorus, and Sulfur Co-Doped Hollow Carbon Shell as Superior Metal-Free Catalyst for Selective Oxidation of Aromatic Alkanes

Shuliang Yang, Li Peng

Metal-free heteroatom-doped carbocatalysts with a high surface area are desirable for catalytic reactions. In this study, we found an efficient strategy to prepare nitrogen, phosphorus, and sulfur co-doped hollow carbon shells (denote as NPS-HCS) with a su ...

Hydrocarbon adsorption in an aqueous environment: A computational study of alkyls on Cu(111)

Oliviero Andreussi

Hydrocarbon chains are important intermediates in various aqueous-phase surface processes, such as CO2 electroreduction, aqueous Fischer-Tropsch synthesis, and aqueous phase reforming of biomass-derived molecules. Further, the interaction between water and ...

Anti-angiogenic properties of chlorambucil derivatives with fluorous and hydrocarbon appendages

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu, Andrea Brett Gasser

Chlorambucil (CLB) derivatives with long fluorous (referred to as 1 and 2) or hydrocarbon (3) chains have been evaluated in a series of in vitro and in vivo assays. In cell viability inhibition assays, both derivatives 2 and 3 show selective cytotoxicity t ...

Nanoparticle - Ionic Liquid Based Catalytic Systems

Alena Karakulina

In recent years ionic liquids have emerged as an important class of compounds for the synthesis of metal nanoparticles. The significant advantage of using ionic liquids is their dual role of reaction solvent and nanoparticle stabilizer. The variability of ...

Synthesis of Azoimidazolium Dyes with Nitrous Oxide

Rosario Scopelliti, Kay Severin, Euro Solari, Alexander Tskhovrebov

A new method for the synthesis of industrially important azoimidazolium dyes is presented. The procedure is based on a reagent which is rarely used in the context of synthetic organic chemistry: nitrous oxide (“laughing gas”). N2O is first coupled to N-het ...
