为实现低品质风化煤资源的高值高效利用和对含酚废水的清洁治理，以低品质风化煤(CCM)为原料，分别添加 ZnCl2，KOH 和 H3PO4等活性剂，采用浸渍混合-氮气焙烧工艺制备了3种煤基过硫酸盐催化材料，利用 XRD，SEM，BET，FT-IR 和 XPS 等手段对其进行了表征，并研究了其用于活化过一硫酸盐(PMS)催化降解水中苯酚的性能。结果表明：以 ZnCl2 为活化剂制备的催化材料(CCM-ZnCl2)具备较高的催化活性，其反应速率常数是未添加活性剂样品的 63.7 倍；添加的活性剂 ZnCl2 与风化煤生成了硅锌矿，说明新物质的引入在热处理过程中促使了物相转变。CCM-ZnCl2 对 PMS 的优异的活化性能可归结为以下原因：ZnCl2 作为活性剂的加入使风化煤具有更大的比表面积、更高的孔体积和更小的孔径，从而获得更好的吸附性能；CCM-ZnCl2 材料丰富的边缘缺陷可拉长 PMS 的氧氧键，促进电子由苯酚转移至活化的 PMS，从而通过非自由基路径(通过产生1O2)来实现苯酚的快速降解。 由自由基实验可得，CCM-ZnCl2 / PMS/ 苯酚体系中活性物种包括SO·-、·OH和1O ，其中1O 占主导地位;由pH和阴离子降解实验可得，pH(3.0~11.0)和阴离 422子(Cl- ，H PO- ，HCO- 和 SO2- )对 CCM-ZnCl / PMS 体系影响不明显，表明 CCM-ZnCl 催化材料在 243422实际废水治理领域具有良好的应用前景。

In order to realize high⁃value and efficient utilization of low⁃quality weathered coal resources (CCM) and clean treatment of phenol containing wastewater，coal⁃based persulfate catalytic materials were successfully fabrica⁃ ted by the means of impregnation and calcination in nitrogen with the addition of ZnCl2，KOH or H3PO4. The synthe⁃ sized materials were characterized by X - ray diffraction， scanning electron microscope， BET measurement， Fou⁃ rier transform infrared spectroscopy and X-ray photoelectron spectroscopy，and its ability to activate PMS for catalyt⁃ ic degradation of phenol in water were deeply studied. The results indicated that CCM-ZnCl2had the best catalytic activity，and its reaction constant was 63.7 times higher than that of the bulk CCM. The addition of active agent ZnCl2 and weathered coal formed silicon zinc ore， indicating that the introduction of new substances promoted the phase transformation in the process of heat treatment. The excellent activation performance of CCM-ZnCl2 for PMS can be attributed to the following reasons:the addition of ZnCl2 as an activator makes the weathered coal have larger specific surface area，higher pore volume and smaller pore diameter，so as to obtain better adsorption performance. The rich edge defects of CCM-ZnCl2 can elongate the oxygen bond of PMS and promote the transfer of electrons from phenol to activate PMS，so as to realize the rapid degradation of phenol through non⁃radical pathway (by producing 1O2). In addition，it is found that SO·- ，· OH and 1 O were involved into CCM-ZnCl / PMS / phenol system from the free radical experiment，and 1 O2 played the major role during the oxidation process.Moreover，CCM-ZnCl2 / PMS system possessed a relative wide working pH range ( 3. 0 - 11. 0 ) and exhibited the superior stability in the presence of common anions (i.e.，Cl- ，H PO- ，HCO- and SO2- ) from pH and anion degradation experiments. To sum up，CCM-ZnCl is an efficient and cheap PMS activator with good catalytic and anti⁃interference performance which might be comprehen⁃ sively utilized in the field of actual wastewater treatment.
