Abstract
The reaction of a biphasic catalysis with microgels bearing catalytic groups adsorbed at liquid interface was simulated for the first time using dissipative particle dynamics. It was shown that the rate of the catalytic process increases with the degree of deformation of the polymer network, which depends on the fraction of the crosslinker and the solubility of the polymer in both phases. It was found that the highest reaction rate was observed when the microgel was soluble in both phases due to an increase in its porosity (in comparison with amphiphilic microgels) and in the water–microgel–oil contact area with a simultaneous decrease in the time for the reagents to reach the catalytic groups due to the flattening of the microgel. The results obtained can be useful for increasing the efficiency of a wide range of catalytic reactions of the type considered through the use of network-like macromolecules.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
