Abstract：Low-temperature SCR denitration is one of the current research highlights in de-NOx field. Developing efficient and stable SCR catalysts under low temperature conditions(<300 ℃) is the key to solve the problem.Carbon-based materials have developed pore structures and high specific surface area, which can provide space and surface support for the loading of active catalytic components. Carbon-based catalyst for low-temperature de-NOx technology has broad development and application prospects. The present work introduces the low-temperature deNOx reaction mechanism and the commonly used carbon-based materials, and analyzes the factors affecting the low-temperature de-NOx performance of carbon-based catalysts. Moreover, it summarizes the research progress of carbon-based catalysts from the aspects of pre-treatment to enhance oxygen-containing functional groups, active components to improve de-NOx performance, reasonable calcination to enhance de-NOx performance, and antipoisoning to maintain stable denitrification performance. Finally, the prospective future development directions and suggestions are given.
