This chapter takes you through the principal stages of a Catalysis development, covering the main features. We recommend that if you read a single chapter of this book, this should be the one. For a greatly abbreviated sound-bite version of the tour, see Section 1.15, Summary. 

This chapter provides an overview of the Catalysis development process, describing how development artifacts can be structured, developed, and evolved on a typical project. The case study used in the next four chapters illustrates specific application of this process to a sample problem but does not illustrate all nuances of a complete development.

Dr. Zhang holds several adjunct professorships, including one at the University of Waterloo and one at the University of British Columbia. His research is mainly based on fuel cell catalysis development. He has coauthored more than 200 publications, including 150 refereed journal papers and three edited books. Fie also holds over 10 US. patents and patent publications. Dr. Zhang is an active member of the Electrochemical Society, the International Society of Electrochemistry, and the American Chemical Society. 

Control of the multitude of pathways which feed molecules can take is the primary objective of aU catalyst and process developments. The work covered in this chapter focuses primarily on describing the approaches in material and catalysis development which have led to major advances in zeolite application in hydrocarbon conversion. The breaking and formation of carbon-carbon and carbon-hydrogen bonds constitute the majority of the chemical transformations involved here with the less prevalent, but very important, breaking of carbon bonds with sulfur, nitrogen and oxygen taking place in parallel. 

Enantioselective -Functionalization of Aldehydes and Ketones The direct and enantiosective functionalization of enolates or enolate equivalents with carbon-, nitrogen-, oxygen-, sulfur- or halogen-centered electrophiles represents a powerful transformation of chemical synthesis and of fundamental importance to modem practitioners of asymmetric molecule constmction. Independent studies from List, J0rgensen, Cordova, Hayashi, and MacMiUan have demonstrated the power of enamine catalysis, developing catalytic enantioselective reactions such as... 

Although the latent principle of catalysis was not recognized at the time, catalysis was already used in antiquity. For example, enzymes (biocatalysts) catalyze the malting procedure in beer brewing (6000 be) or the preparation of bread and other leavened bakery products by carbon dioxide and alcohol (2000 be). However, the scientific method for catalysis development only began about 200 years ago, and its importance has continued to grow until the present day. 

For catalysis development our modeling highway can be explored to see what scenarios fit the data. Predictions of new catalysts are based on that information this may give the desired performance for those catalysts, or at the very least there are new data that could improve the model. The data are useful to revise the model, whether they indicate negative or positive results. Guided experimental design will indicate what part of combinatorial space should be explored. 

Catalysis development and understanding are essential to most chemical synthesis advances and therefore require new materials able to steer the reactions towards identified target products. Because the topic of chemical synthesis is so broad and catalysis is so crucial to chemical synthesis, a significantly higher speed and efficiency in new materials discovery and process optimisation is required today to ...

One of the most intensively studied interfaces is the electronic conductor/ionic conductor where the interest is motivated by attempts to prevent corrosion and to improve the catalytic properties of metallic deposition. Both corrosion prevention and catalysis development can be described using an electrochemical and engineering approach, including film formation and growth and its optimization in the cell reactor.
