摘　　要：利用共沉淀法原位制备活性炭复合镁铝水滑石,考察活性炭和水滑石不同比例对电化学性能的影响,并对产物进行了XRD表征。结果表明:XRD表征图谱中,样品有水滑石的特征衍射峰,说明原位合成法得到的样品具有较好的晶型。电化学测试表明,不同比例的样品其电容性能不同,活性炭与水滑石比例为1∶10时,所得样品的电容量相对较高。Activated carbon combination with magnalium-alumina Layered Double Hydroxide （AC/Mg-Al synthesized in situ by coprecipitation method, and the effects of ratio between carbon combination and layered double hydroxide were investigated The final material was investigated AC/Mg-Al LDH of differen ratio, it was found that the ratio of AC/Mg-Al LDH have a more uniform structure present in X-ray diffraction curve. magnali LDH） were um-alumina by X-ray diffraction. Based on the analyses of was obtained using 1 ： 10 have a highest and have a more uniform structure present in X-ray diffraction curve.
