Preparing method for porous Fe-Si-C ceramic micro balls
A preparing method for porous Fe-Si-C ceramic micro balls comprises the following steps that firstly, poly-ferrocenylsilanes is dissolved in an organic solvent and stirred, deionized water and a surface active agent are added or not added, stirring is carried out, and a component a is obtained; secondly, gelatin or polyving akohol are dissolved in the deionized water, stirring is carried out, and a component b is obtained; thirdly, the component a is dripped in the component b to continue to be stirred, the mixture stands still, the upper layer emulsion is poured, the deionized water is added for dilution, filtering is carried out, micro balls are collected and cleaned, finally, vacuum drying is carried out, and polymeric micro balls are obtained; fourthly, the polymeric micro balls obtained in the third step are sintered and split in a tubular stove, and the porous Fe-Si-C ceramic micro balls are obtained. The preparing method is simple and convenient to implement, the shape of the obtained porous Fe-Si-C ceramic micro balls is regular, a multi-level pore structure is arranged inside, a large number of nanometer Fe particles with the catalysis function are evenly distributed, and the porous Fe-Si-C ceramic micro balls have very good application prospects in the catalyst carrier field.
