英文摘要Many organic compounds will spontaneously disperse on the surface of a solid support to form monolayers, in a manner similar to that of inorganic salts and oxides, and numerous materials with useful properties can be designed and prepared based on this phenomenon. The dispersion behavior and orientation of organic compounds in monolayers depend not only on the molecular structure of organic compounds but also on the surface features and pore structure of the support. This short review summarizes the applications of monolayer-dispersed organic compounds in the preparation and texture control of related materials, including carbon/oxide composites, various other oxides, and mesoporous carbon with thin pore walls. Pyrolysis of organic monolayers can be used to prepare carbon/oxide composites with a uniformly thin carbon layer for use as photocatalysts, catalyst supports, and adsorbents for dyes. During the sol-gel preparation of porous oxides, organic monolayers can also prevent the aggregation of sol particles, thus producing oxides with high specific surface areas and adjustable pore volumes; gamma-Al2O3 with a specific surface area as high as 506 m(2).g(-1) can be prepared in this manner. During calcining under an inert atmosphere, the carbon layer in the aforementioned carbon/oxide composites can significantly inhibit the phase transformation of oxides. Calcining carbon/gamma-Al2O3 in oxygen at high temperatures, however, results in a rapid gamma to a phase transformation. The oxides in these composites can also act as templates for the preparation of carbon materials. Dissolving the support oxides is a convenient method for the preparation of mesoporous carbon materials with high specific surface areas, large pore volumes, high mesopore ratios, and thin pore walls. The morphology and size distribution of pores in these carbon materials can be controlled by choosing oxides with different textures.
