| Abstract |
The previous study about methodology that enlarge the utility of solid-state reactions was reported. They suggest a synthetic route for producing a high-diversity pool of nanocrystals (NCs) by circumventing the problematic sintering of nanocrystals at high temperatures.1)
As an extension and utilization of this study, metal nanocrystals confined in mesoporous carbon foam (MCF) were prepared by modulated synthetic method. All we have to do for the final M@MCF material is simple three steps. Synthesis of M/SiO2 particles that we want to put in the cavity, annealing them with carbon source, and removing the silica. The simple modulated synthetic method make it possible to have metal crystals of various composition in these materials. In this M@MCF system, metal crystals are separated from each other by mesoporous carbon shells so that sintering/aggregation can be prevented. Mesoporous carbon materials provide high mass transport property and conductivity. These properties make the possibility of these material as a complicate organic reaction catalysts or an electrochemical catalysts.
