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 de-NOx 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 anti-poisoning to maintain stable denitrification performance.Finally,the prospective future development directions and suggestions are given.
