以煤液化残渣为原料，通过模板法合成泡沫炭和催化化学气相沉积法（CCVD）制备了泡沫炭（CNF）/泡沫炭复合材料。高溶解度和高热解产率使其成为模板法合成炭材料的一种很有前途的炭前驱体。泡沫炭的泡孔尺寸约为500μm，孔隙率高达95 vol.%。在CCVD过程中，天然存在于泡沫中的Fe物种均匀地分散在充当催化剂的碳泡沫的表面上。CCVD处理后，碳泡沫的整个表面被缠绕的CNF覆盖，CNF的外径为20- 100 nm，长度为几十微米。所得到的CNF/碳泡沫复合材料是有效的选择性吸附剂在油和水的分离，通过疏水性和毛细管作用的组合。
A carbon nanofiber (CNF)/carbon foam composite was fabricated from coal liquefaction residue (CLR) through a procedure involving template synthesis of carbon foam and catalytic chemical vapor deposition (CCVD) treatment. The high solubility and high pyrolysis yield make CLR a promising carbon precursor for the synthesis of carbon materials using the template method. The carbon foam has cell size of about 500μm and a porosity as high as 95vol.%. Fe species naturally present in the CLR disperse homogeneously on the surface of the carbon foam acting as a catalyst in the CCVD process. After the CCVD treatment, the whole surface of the carbon foam is covered by entangled CNFs with external diameters of 20–100nm and lengths of several tens of micrometers. The obtained CNF/carbon foam composites are effective selective adsorbents in the separation of oil and water, through a combination of hydrophobicity and capillary action.
