采用S t?ber法，以间苯二酚和福尔马林为原料，制备了单分散，粒径可控的碳球。讨论了醇/水比、不同种类的醇、水浴温度、反应物和氨水添加量等对碳球粒径和形貌的影响，并通过SEM 、FT-IR、XRD和DLS对最终产物的粒径、形貌和组成进行了表征。结果表明：随着醇/水比、醇的烷链、反应物和氨水的添加量增加时，碳球的粒径变大，且粒径分布在370～1050 n m之间；最佳水浴温度为30℃；碳球具有强的吸附作用，以碳球为牺牲模板，制备出了粒径分布均匀的空心ZnO/ZnFe2 O4纳米球。

Carbon spheres were synthesized by St?ber method in mixed resorcinol and formal-dehyde ,with monodisperse and controllable particle size .The effects of the alcohol/water ra-tio ,the alkyl chain of alcohol ,the initial reaction temperature ,the reactants dosage and the ammonia dosage ,on the particle size and the morphology of phenolic formaldehyde micro-spheres were discussed .Carbon spheres were observed by SEM ,FT-IR ,XRD and DLS .It is found that the size of monodisperse phenolic formaldehyde microspheres tends to increase with the augment of the alcohol/water ratio ,the alkyl chain of alcohol ,the reactants dosage and the ammonia dosage ,and the particle size of the phenolic formaldehyde microspheres can be tuned from 370 to 1 050 nm ;optimum initial reaction temperature is 30 ℃ ;carbon spheres with strong adsorption ,serving as sacrificial template ,were prepared hollow ZnO/ZnFe2 O4 nanospheres .
