Catalysis is a term describing the process of increasing the rate of a chemical reaction by adding a small amount of a substance known as a catalyst, which is not consumed in the reaction and can be re-used several times as it undergoes no net chemical change. 2 Despite the word catalysis being first introduced by Berzelius in 1835, 3 the first definition based on physical chemistry principles was given in 1894 by Ostwald 4 and it is still used nowadays. 1 Over 75% of all chemicals are fully or partially obtained through a catalytic process and up to 90% of newly developed routes involve the use of catalysis. Introduction Catalysis is a well established and widely used strategy in the pharmaceutical and fine chemical industries. He was awarded the RSC Surfaces and Interfaces Award in 2014 and the ACS Langmuir Lectureship in 2016 and is currently a Senior Editor for Langmuir.ġ. He has published 325 refereed papers, 16 patents and edited 3 research monographs. This includes particle-stabilised emulsions, aqueous foams and oil foams. Since 1998 his main research interest has been the behaviour of colloidal particles at fluid interfaces including oil–water, oil–oil, water–water, air–water and air–oil. He led the Surfactant and Colloid Group for 15 years with interests in surfactant phase behaviour, surfactant-stabilised foams and emulsions and wetting. Binks is Professor of Physical Chemistry at the University of Hull since 2003. Her research interests includes particles at fluid interfaces, colloids and emulsions. Binks (2018) investigating polyelectrolyte complexes as soft Pickering emulsion stabilisers. She then moved to the University of Hull, where she obtained her PhD in Physical Chemistry under the supervision of Prof. She obtained her Master in Analytical Chemistry from the Institut Químic de Sarrià (IQS), Ramon Llull University (Spain) in 2015. Binks at the University of Hull (U.K.), where she uses Pickering emulsions as vehicles to carry out catalytic reactions. Finally, the importance of using Pickering emulsions to carry out reactions in flow and in multi-step cascade systems is highlighted with various examples to support the benefits of transferring this technology to industrial processes.Īna María Bago Rodríguez is currently a postdoctoral researcher under the supervision of Prof. A section describing methods for recovering the catalyst is also included, in which various stimuli are discussed. An overview is given regarding the kinds of liquid phases comprising the emulsion system, the different types of solid particle stabilizers (whether they contain catalyst or not) and the catalytic reactions studied. As the area has advanced rapidly, the intention of this review is to summarize the latest innovations being reported. In the past 10 years a new application has emerged in the field of catalysis to use them as vehicles to carry out catalytic reactions, allowing a more environmentally friendly process with high conversions and selectivities and important advantages for catalyst recovery. Particle-stabilised or Pickering emulsions are versatile systems.
