摘      要：A simple strategy for the synthesis of macro-mesoporous carbonaceous monolith materials has been demonstrated through an organic organic self-assembly at the interface of an organic scaffold such as polyurethane(PU)*** porous carbonaceous monoliths with cubic(Im m)or hexagonal(p6mm)mesostructure were prepared through evaporation induced self-assembly of the mesostructure on the three-dimensional(3-D)interconnecting struts of the PU foam *** preparation was carried out by using phenol/formaldehyde resol as a carbon precursor,triblock copolymer F127 as a template for the mesostructure and PU foam as a sacrificial monolithic *** hierarchical pore system was macroscopically fabricated with cable-like mesostructured carbonaceous *** carbonaceous monoliths exhibit macropores of diameter 100450μm,adjustable uniform mesopores(3.87.5 nm),high surface areas(200870 m2/g),and large pore volumes(0.170.58)cm3/*** with the corresponding evaporation induced self-assembly(EISA)process on a planar substrate,this facile process is a time-saving,labor-saving,space-saving,and highly effi cient pathway for mass production of ordered mesoporous materials.
