Reactions at the Liquid-Solid Interface book cover

Reactions at the Liquid-Solid Interface

Volume 28 of Comprehensive Chemical Kinetics is concerned with reactions occurring at the solid-liquid interface. Volumes 26 and 27 have dealt with electrochemical reactions. The present volume therefore covers those interfacial processes which involve no net passage of current. The first chapter covers the structure of the interfacial region and its experimental investigation. The second chapter reviews the mechanisms by which heterogeneous catalysis of solution reactions can take place. The third is concerned with the mechanism and kinetics of crystal growth from solution. The final chapter deals with corrosion processes at the metal-solution interface.
