The efficient mitigation of harmful nitrogen oxides (NO_x) under ambientconditions remains a challenging task。 Selective adsorption offers a viablesolution for the capture of low-concentration NO_x from the polluted streamat low temperatures。 This review summarizes recent progress in thedevelopment of NO_2 adsorbents， delves into the understanding of adsorptionmechanisms， and discusses the criteria for evaluating their performance。First， the present NO_2 adsorbents are categorized according to their distinctcharacteristics。 This review then provides insights into the mechanisms ofadsorption， highlighting the interaction between active sites and NO_2，drawing from both experimental and theoretical research。 The performance ofthese adsorbents is also assessed， focusing on their capacity， reusability，stability and selectivity。 Finally， perspectives are proposed to address thesignificant challenges and explore potential advancements for NO_2adsorbents， aiming to enhance their suitability for diverse practicalapplication scenarios。
