Heteroatom dopants in carbon materials allow enhanced catalytic activities, which are essential to open up new applications of carbocatalysts. In this presentation, we present bottom-up design of functional carbon materials using microporous organic polymers that provide thermal stability and synthetic flexibility; thus, sequential heat treatment caused elemental engineering of carbonaceous materials without the need for additives or extra processes. The carbonized materials were found to contain heteroatom dopants originated from the carbon precursors as designed, and to show superior catalytic behavior. As an example, the sulfur atoms could provide reactive sites when doped, which thus imparted the carbonized materials with enhanced performance in hydrogen evolution reactions when compared with un-doped materials. |
