Size and Shape-controlled Pd Nanocrystals on ZnO and SiO2: When the Nature of the Support Determines the Active Phase

Lioubov Kiwi, Rocio Micaela Crespo Quesada

The structure sensitivity of acetylene hydrogenation was studied over size-controlled cubic and octahedral Pd nanocrystals (NCs) supported on ZnO and SiO2. Acetylene hydrogenation was found to be structure sensitive [with Pd(111) in octahedra being more ac ...

Use of Empty Fruit Bunches from the Oil Palm for bioethanol production: A thorough comparison between dilute acid and dilute alkali pretreatment

Edgard Gnansounou, Simone Chiesa

In the present work, two pretreatment techniques using either dilute acid (H2SO4) or dilute alkali (NaOH) have been compared for producing bioethanol from Empty Fruit Bunches (EFBs) from oil palm tree, a relevant feedstock for tropical countries. Treatment ...

Hydrogen Production by Selective Dehydrogenation of HCOOH Catalyzed by Ru-Biaryl Sulfonated Phosphines in Aqueous Solution

Gabor Laurenczy, Katerina Stefania Sordakis

The selective dehydrogenation of aqueous solutions of HCOOH/HCOONa to H2 and CO2 gas mixtures has been investigated using RuCl3·3H2O as a homogeneous catalyst precursor in the presence of di␣erent monoaryl-biaryl or alkyl-biaryl phosphines and aryl diphosp ...

Heterogeneous Silica-Supported Ruthenium Phosphine Catalysts for Selective Formic Acid Decomposition

Paul Joseph Dyson, Gabor Laurenczy, Weijia Gan

The water-soluble ruthenium(II)–mTPPTS complex (mTPPTS= meta-trisulfonated triphenylphosphine) efficiently catalyzes the generation of hydrogen from formic acid in aqueous solution. This catalyst has been immobilized in a hydrophilic silica sup- port to fa ...

Direct, in situ determination of pH and solute concentrations in formic acid dehydrogenation and CO2 hydrogenation in pressurised aqueous solutions using 1H and 13C NMR spectroscopy

Paul Joseph Dyson, Gabor Laurenczy, Séverine Joëlle Moret

In water, spin–lattice relaxation times (T1) and calibration curves for chemical shifts have been determined for the 13C and the 1H (C) atoms in HCOOH, HCOONa, CO2, Na2CO3 and NaHCO3 by NMR spectroscopy. These data facilitate kinetic and mechanistic studie ...

Synthesis and Properties of Highly-Charged Cationic Polyelectrolytes

Hamideh Ahmadloo

Polyelectrolytes (PEL) and PEL complexes formed by electrostatic interaction are recognized as compounds with a remarkable potential for a wide field of applications. However, comprehensive knowledge about electrostatic and structural influences on the pol ...

Ruthenium(II)-Catalyzed Hydrogen Generation from Formic Acid using Cationic, Ammoniomethyl-Substituted Triarylphosphine Ligands

Paul Joseph Dyson, Gabor Laurenczy, Weijia Gan, Dennis Snelders

The selective catalytic decomposition of formic acid into hydrogen and carbon dioxide has been achieved in water under mild conditions. For the first time, a ruthenium ion in combination with series of oligocationic, ammoniomethyl-substituted triarylphosph ...

Hydrogen storage: beyond conventional methods

Gabor Laurenczy, Martin Grasemann, Weijia Gan, Séverine Joëlle Moret, Andrew Francis Dalebrook

The efficient storage of hydrogen is one of three major hurdles towards a potential hydrogen economy. This report begins with conventional storage methods for hydrogen and broadly covers new technology, ranging from physical media involving solid adsorbent ...

Formic acid: Thermo-economic evaluation

With regard to sustainability it is often referred to the “Hydrogen Economy” as an alternative to cover the energy needs by using hydrogen as a fuel source. The goal of this project is to study the production of hydrogen by using the formic acid decomposit ...

Biphasic Model Describing Soybean Oil Epoxidation with H2O2 in Continuous Reactors

Albert Renken

Epoxidized soybean oil (ESBO) is produced in industry by reacting soybean oil, at 60-70 degrees C, with hydrogen peroxide in the presence of formic or acetic acid. A small amount of sulphuric or phosphoric acid is necessary to catalyze the oxidation of the ...
