Predictive Heterogeneous Catalysis by Design: well-defined Single-site Catalysts

We have reached a level of understanding of heterogeneous catalysis, so that this domain can be fully rationalized by the rules of molecular chemistry applied to surface. The methodology is based on the synthesis of single site catalysts by reacting organometallic compound with surfaces. The choice of the organometallic is based on the modes of formation and cleavages of bonds coming from molecular chemistry. One tries to enter a catalytic cycle by a selected surface organometallic fragment. So heterogeneous catalysis is fully predictable.

Surface Science in Catalysis: Fischer-Tropsch Research

In this presentation we briefly introduce the most important surface science techniques and show applications from single-crystal metals and two-dimensional models of supported catalysts to reveal mechanistic information on syngas and Fischer-Tropsch reactions. We particularly highlight the superior opportunities for reaction mechanistic research at synchrotrons using near-ambient pressure photoelectron spectroscopy.

Electro-Catalysis at the Atomic Scale

The challenge of discovering new catalyst materials is twofold: Firstly, the properties or descriptors of the wanted catalyst have to be identified. Secondly, real materials with the wanted properties should be found. I will give examples of determining descriptors for different reactions and a method for identify promising catalyst materials based on high entropy alloy, which is a new class of materials with the promise to change the way we discover interesting catalyst materials.

Supported Catalytically Active Metal Solutions (SCALMS) – Single Atom Catalysis for Technical Alkane Dehydrogenation)

We demonstrate that Supported Catalytically Active Liquid Metal Solutions (SCALMS) offer the potential for new and unusual catalytic reactivity in alkane dehydrogenation. Results from reaction engineering, spectroscopy, microscopy and theoretical calculations prove the importance of fully liquid nature of supported Ga-Pd or Ga-Rh alloy droplets under the applied reaction conditions.

Tandem Catalysis For Syngas Conversion: Disentangled Control Over Spatial And "Chemical" Proximities Of Integrated Solid Catalysts

The integration of two solid catalysts in a single reactor, to steer sequential reactions in tandem, is an attractive for process intensification. However, the dichotomy is faced that close spatial proximity between the integrated catalysts –for an effective transport of intermediate products between their active sites– prohibits individual adjustment of other key parameters such as the operation temperature. Progressing towards a disentangled control over this reaction parameters might open new horizons for tandem catalytic processes.

Catalyst characterization in an industrial context

The term “Catalyst Characterization” conjures up different interpretations amongst those involved in either the science or the business of catalysis. For many, it is regarded as the preserve of Research & Development (R&D), where it takes the form of sophisticated tools and techniques supporting catalyst innovation. Now whilst this is indeed partly true, the characterization of catalysts actually plays a far more pervasive role in the realisation of catalysis science to final performance in a full-scale industrial process. The aim of this presentation is to demonstrate the crucial position that catalyst characterization occupies in driving catalyst innovation right through to eventual deployment in service. To do this, I will break down the catalyst development life-cycle into the principal stages of: R&D, Manufacture and Operational Service, then show with selected examples, how characterization serves to enable progression from an idea to eventual beneficial productivity. I will attempt to use examples that reveal many of the existing challenges still facing catalyst development scientists today. The overall intent of this presentation is to instil a more holistic attitude and approach to the purpose and importance of good catalyst characterization amongst those of you who are, or intend to become, devoted to the science and application of catalysis.

Microkinetic evaluation of solid-catalyzed gas-phase reactions

Microkinetic analysis of solid-catalyzed gas-phase reactions is presented using an applied approach starting with intrinsic rate expressions based on chemical adsorption and surface reaction, and proceeding to global rate expressions that superimpose individual and simultaneous effects of physical interphase and intraparticle transport processes occurring at the particle scale.

Microkinetic analysis of complex chemical reactions

Catalysis is the art and science of diverting a reaction’s course from its natural path, temporarily. During the detour, molecules meet new companies, break and make bonds that is not in their steady paths, neither energetically nor sterically. Understanding the paths that occur both in the presence and in the absence of the catalysts allows one to make proper selection of the active ingredients in the catalysts, as well as supports and promoters. Furthermore, a good clear understanding of the paths at the molecular level allows one to engineer the process parameters in terms of flow rates, temperature and pressures. In this talk, the molecular events at the individual bond making level and their implications in terms of microkinetics will be discussed.

Formation Mechanism of Nanoparticles: Is the LaMer’s Model of Instantaneous Nucleation and Diffusion-Controlled Growth Usable?

Understanding the formation mechanism is of paramount importance for the synthesis of nanoparticles of controllable size and size distribution. A qualitative version of LaMer’s 1950 model, “burst” nucleation and “diffusion-controlled” growth, is still heavily cited. After a historical look back at LaMer’s model, the question, whether the LaMer model is applicable to the nanoparticle formation system, will be addressed.

Why Silver Is the Unique Catalyst for Ethylene Epoxidation But Not for Propylene Epoxidation: A Quantum Mechanical Answer.

Environmental and economic drawbacks of conventional PO processes necessitate new methods such as direct PO epoxidation similar to silver catalyzed industrial EO process. Quantum mechanical computations find that only Ag2O(001) surface enables direct path for EO without a barrier. PO can also be formed on the Ag2O surface. However, desorption of PO from the surface has a high barrier leading to total combustion and low PO selectivity.
