Design of Aerosol Nanoparticles for Interfacial Catalysis.

Interest in multifunctional nanoparticles is currently rising due to the increasing demand in green energy and environmental applications. The aerosol-based synthetic route emerges as a promising method for enabling the fabrication of multifunctional nanoparticles in a continuous and scalable manner. Meanwhile, interfacial catalysis is receiving great attention to enhance the performance of chemical reactions. In this regard, the utilization of aerosol nanoparticles is highly beneficial to the catalysis field by the creation of strong metal-support-promoter interactions for promoting interfacial catalysis. In this Perspective, aerosol-based synthesis of hybrid nanoparticles is briefly discussed. In addition, the interfacial catalysis of CO oxidation, methane combustion, CO 2 hydrogenation, and dry reforming of methane are discussed to provide fundamental insights and concepts for the rational design of nanocatalysts with efficient interfaces.
