研究目的
通过可控碳化废弃聚丙烯，制备用于太阳能蒸汽生成的低成本、高效光热材料。
研究成果
采用NiO与PIL-X复合催化剂对聚丙烯进行可控碳化制备Ni/CNM材料。其中Ni/CNM-I展现出1.67 kg m?2 h?1的高蒸发速率及高达94.9%的太阳能-蒸汽转化效率，优于现有碳基光热材料。该研究为海水淡化领域作出贡献，并提出将废弃聚合物转化为高附加值碳纳米材料的可持续新途径。
研究不足
该研究聚焦于聚丙烯的可控碳化及镍/碳纳米材料在太阳能蒸汽生成中的应用。但未深入探讨该工艺在工业应用中的可扩展性与长期稳定性。
1：实验设计与方法选择：
以NiO和聚离子液体（PIL）为复合催化剂，对聚丙烯（PP）进行可控碳化制备镍/碳纳米材料（Ni/CNM）。
2：样品选择与数据来源：
从武汉某餐馆收集的废弃PP杯。
3：实验设备与材料清单：
PP颗粒、NiO纳米颗粒、PIL、乙醇、亚甲基蓝、罗丹明B、二甲基聚硅氧烷和盐酸。
4：实验步骤与操作流程：
将PP与NiO和PIL混合，在坩埚中以750°C加热8分钟，并对所得Ni/CNM进行表征。
5：数据分析方法：
通过SEM、TEM、HRTEM、XRD、拉曼光谱、TGA、N?吸附/脱附测量、紫外-可见-近红外分光光度计和导热仪进行表征。
