The invention discloses a high-performance carbon nano-material adsorbent and preparation and application thereof. The high-performance carbon nano-material adsorbent is composed of a carbon nano-material and an adhesive. Mass fraction of the carbon nano-material is 80-97 wt%. Specific surface area of the adsorbent is 800-2200 m /g. The pore volume ratio of micropore to mesopore to macropore is (1-3): (1-6): (1-10). The invention also discloses a method for directly preparing the adsorbent by the utilization of a compound of the carbon nano-material obtained during the chemical vapor deposition process and an inorganic compound carrier. The adsorbent has advantages of long service life, large handling capacity, low preparation cost, etc., and is especially suitable for adsorption of low-concentration nonpolar organic matter in a fluid. 本发明公开了种高性能碳纳米材料吸附剂及其制备与应用，由碳纳米材料与粘接剂组成，碳纳米材料的质量分数为80-97％，吸附剂的比表面积为800-2200m/g，其微孔、介孔与大孔的孔容占比为(1～3)：(1～6)：(1～10)。本发明还公开了利用化学气相沉积过程所得碳纳米材料与无机化合物载体的复合物直接制备该吸附剂的方法，该吸附剂具有使用寿命长，处理量大
