Popis: Named after the Roman god of doors, Janus nanoparticles are anisotropic materials possessing two sides of different physicochemical properties, namely, divergent polarity or chemical nature. Self-assembling and surface activity make these materials of special interest in diverse applications, such as drug delivery, sensoring, data storage, and catalysis. Janus nanoparticles are characterized by having two well-defined regions with different physicochemical properties (phase affinity, compartmentalized chemical composition, or both). This chapter, concerns catalytic application of Janus nanoparticles which is in its infancy. Janus nanoparticles constitutes an interesting alternative for liquid phase heterogeneous catalysis. Especially, because their surface activity Positions them exactly at the liquid/liquid interface, acting both as surfactants (to stabilize liquid/solid/liquid interfaces in Pickering emulsions) and as catalysts by providing active sites for emulsified reaction systems.
