Thermodynamic-Kinetic Precipitation Modeling. A Case Study: The Amorphous Calcium Carbonate (ACC) Precipitation Pathway Unravelled

Christian Ludwig, Paul Bowen, Andrea Testino, Agnese Carino, Mohammad Reza Andalibi, Frank Pilger

Nine accurate experimental data sets on amorphous calcium carbonate (ACC) formation in dilute solution were collected varying temperature and pH. The entire precipitation process is described using a complete thermodynamic-kinetic model. The thermodynamic ...

Advanced Nanopowder Synthesis : Characterization, Performance and Kinetics of CeO2-based Supports, Catalysts and Segregation Processes

Frank Pilger

CeO2-based nanomaterials and their rich redox chemistry provide a possible route to pollutant abatement in various heterogeneous processes, and are in particular used as sorbents for flue gases and as oxygen promoters in three-way catalytic converters. The ...

Size control of Pt clusters on CeO2 nanoparticles via an incorporation-segregation mechanism and study of segregation kinetics

Christian Ludwig, Andrea Testino, Agnese Carino, Frank Pilger

Recent literature on Pt/CeO2 catalysts reveals that ionic Pt species could be incorporated into the CeO2 lattice. Here we present a detailed study of Pt segregation in air and under a reducing atmosphere conducted on thermally treated samples by high-resol ...

Continuous Polyol Synthesis of Metal and Metal Oxide Nanoparticles Using a Segmented Flow Tubular Reactor (SFTR)

Paul Bowen, Andrea Testino, Christoph Stähli, Jose Enrico Quijano Quinsaat, Frank Pilger

Over the last years a new type of tubular plug flow reactor, the segmented flow tubular reactor (SFTR), has proven its versatility and robustness through the water-based synthesis of precipitates as varied as CaCO3, BaTiO3, Mn((1-x))Ni(x)C(2)O(4)2H(2)O, YB ...

One-Pot Polyol Synthesis of Pt/CeO2 and Au/CeO2 Nanopowders as Catalysts for CO Oxidation

Christian Ludwig, Andrea Testino, Mohamed Tarik, Frank Pilger

The facile one-pot synthesis of CeO2-based catalysts has been developed to prepare a relatively large amount of nanopowders with relevant catalytic activity towards CO oxidation. The method consists of a two-steps process carried out in ethylene glycol: in ...
