Catalysis continues to be a strong and engaging area of research. New tools are being used to explore the complex processes taking place at the catalyst surface. Conversion of both traditional and new fuels to meet the challenge of clean energy is becoming more important. The reviews in this volume address these topics.

Jim Goodwin, Jr. and colleagues at Clemson University (Edgar Lotero, David
Bruce, and Kaewta Suwannakarn, Yijun Liu, and Dora Lopez) review the
application of solid acid catalysts for the synthesis of biodiesel from renewable
sources. Biodiesel is produced by the acid-catalyzed esterification of fatty acids
derived from renewables such as vegetable oil. Although this esterification can be
carried out using homogeneous acid catalysts, there are clear process advantages
to using heterogeneous catalysts—provided the necessary activity and selectivity
can be achieved. The authors assess both the current processes that are based on
homogeneous catalysts, as well as recent studies of heterogeneous catalysts,
which have not been extensively reviewed to date.
Nitrides and oxynitrides represent a relatively new class of catalytic material.
Justin Hargreaves and D.McKay (University of Glasgow, UK) show that these
materials have only recently been explored for reactions (e.g., photocatalysis)
beyond those that take advantage of their acid-base properties and their ability
to mimic Pt-based catalysts. Tuning the acid-base properties of nitrides is
possible by incorporating oxygen within their structure.
Cobalt-based Fischer-Tropsch catalysts are the subject of continuing interest
as large-scale Gas-to-Liquids plants come on line. Fernando Morales and Bert
Weckhuysen (Utrecht University, the Netherlands) look specifically at the
effects of various promoters for these catalysts, particularly Mn. The effect of
these promoters in controlling the activity and selectivity of the overall reaction
can be critical in the overall process economics. This chapter also looks at new
spectroscopic techniques that have recently been used to study the effects of
these promoters.
