Metal–Support Interactions in CeO₂- and SiO₂-Supported Cobalt Catalysts: Effect of Support Morphology, Reducibility, and Interfacial Configuration

With the increasing demand for highly efficient and durable catalysts, researchers have been doing extensive research to engineer the shape, size, and even phase (e.g., hcp or fcc Co) of individual catalyst nanoparticles, as well as the interface structure between the catalyst and support. In this work, cobalt oxides were deposited on ceria with rod-like morphology (CeO2NR) and cube-like morphology (CeO2NC) and silica with sphere-like morphology...
