Preparation of a novel nitrogen-containing graphitic mesoporous carbon for the removal of acid red 88.

ABSTRACT: A novel nitrogen-containing graphitic mesoporous carbon was prepared through MnO-templated method using polyacrylonitrile (PAN) as both carbon and nitrogen sources, and MnCO₃ as both template and catalyst precursors. The effects of preparation conditions on the physicochemical properties of obtained samples were systematically investigated. The results showed that as the decrease of the weight ratios of PAN and MnO (2:1-1:4), the increase of carbonization temperature (700-900 °C) and pre-oxidation temperature (180-200 °C), the samples had higher specific surface area, mesopores volume and ratios, up to 507 m²/g, 0.824 cm³/g and 96.83%, respectively. Moreover, the prepared samples presented relatively high graphitic degree and nitrogen contents (~2.21%). The
