(381a) Vinyl Pyridine As a Precursor for Nitrogen-Doped Zeolite-Templated Carbon

Nitrogen-doping of zeolite-templated carbon (ZTC), a model ordered porous carbon adsorbent material, has been the subject of active research since 2005. In this work we present a novel synthetic route to N-doped ZTC using a two-step method by introducing vinyl pyridine (VP) into zeolite Y as the impregnation precursor. After VP impregnation, the resulting product is subjected to chemical vapor deposition (CVD) using either acetonitrile or propylene as the secondary precursor. The zeolite is then removed by dissolving in acid to free the resulting N-doped ZTC; all such materials possess a uniform micropore size distribution, large surface area, and a long-range pore-to-pore ordering originating from the zeolite template. Variation of the VP precursor itself (2-VP compared to 4-VP), the CVD precursor, and other synthesis conditions results in several materials of high importance for intercomparison with up to 5 wt% N content and elevated pyridinic nitrogen over previous N-ZTCs. To obtain N-ZTCs with both a high nitrogen content and well-ordered porosity, further synthetic optimizations will be discussed.
