| Abstract Scope |
Ultra-small functional nanoglue islands, grafted onto high-area silica, can be broadly used for developing supported metal atom/cluster catalysts for energy and environment. We have developed robust synthesis protocols and treatment processes to fabricate various sizes of CeOx functional nanoglue islands with narrow size distributions. In this work, we study the synthesis of CeOx nanoislands of different sizes and their size-dependent catalytic performance. Electron microscopy, powder X-ray diffraction, and X-ray photoelectron spectroscopy techniques were used to characterize the nature of the CeOx nanoislands supported on commercially available fumed silica. Oxidation of carbon monoxide was used as a probe to evaluate the catalytic and redox properties of the various sizes of the CeOx nanoislands. It is expected that the sizes of the CeOx nanoislands significantly modify the catalytic properties of CeOx-confined metal atoms and clusters, enabling fine-tuning of desirable catalytic reactions. |
