Carbon-inorganic composites belong to group of modern nanomaterials possessing high potential in many applications. Such adsorbents combine characteristics of nonpolar carbon phase and polar inorganic matrix. Both porosity and texture of composites substantially depend on applied carbon precursor, inorganic component and pyrolysis conditions. Novel carbon/alumina composites were prepared using co-polymerization of resorcinol-formaldehyde polymer with fumed Al₂O₃ and subsequent pyrolysis of derived materials in inert atmosphere at 800 °C. Morphological and structural characteristics of as-obtained initial polymeric and carbon-inorganic nanocomposites were studied using powder X-ray diffraction, scanning electron microscopy, Raman spectroscopy, nitrogen adsorption methods, and temperature-programmed desorption mass spectrometry. The experimental results showed that filler Al₂O₃ acting as catalyst has significant influence on the resorcinol-formaldehyde polycondensation reaction and further pyrolysis step, therefore affects the structure of carbon-inorganic composites that is evidenced by the changes of specific surface area and porosity. It was shown that the porosity and texture of prepared composites substantially influenced the adsorption/desorption steps of explosives from aqueous samples. The results provide new ideas on the hybrid composites synthesis as well allow one to elucidate the effect of synthesis method on the structural characteristics of materials which can be used as high quality adsorbents in water treatment.

碳-无机复合材料属于在许多应用中具有很高潜力的现代纳米材料。这种吸附剂结合了非极性碳相和极性无机基质的特性。复合材料的孔隙率和质地都基本上取决于所施加的碳前体，无机成分和热解条件。间苯二酚-甲醛聚合物与热解Al ₂ O ₃的共聚制备了新型碳/氧化铝复合材料然后在惰性气体中于800°C进行热解。使用粉末X射线衍射，扫描电子显微镜，拉曼光谱，氮吸附方法和程序升温脱附质谱研究了获得的初始聚合物和碳无机纳米复合材料的形态和结构特征。实验结果表明，填料Al ₂ O ₃用作催化剂对间苯二酚-甲醛的缩聚反应和进一步的热解步骤有重大影响，因此影响比表面积和孔隙率的变化证明了碳-无机复合材料的结构。结果表明，制备的复合材料的孔隙率和质地明显影响了爆炸物从含水样品中的吸附/解吸步骤。该结果为杂化复合材料的合成提供了新思路，也使人们能够阐明合成方法对可用作水处理中高质量吸附剂的材料结构特性的影响。
