微波辅助催化降解技术因其高效性和可控性，已成为水体有机污染物处理领域的重要研究方向。本研究创新性地以海带为绿色碳源载体，与普鲁士蓝类似物(CoNi-PBA)复合制备了Co-Ni@海带衍生碳复合材料(Co-Ni@KC)。在800 W微波功率下，Co-Ni@KC-3在4 min内对240 mg/L的甲基橙、亚甲基蓝、结晶紫和罗丹明B的降解效率高达99.52%、99.74%、94.67%和99.69%,并展现出优异的循环稳定性。材料的降解机制主要归因于微波催化过程中热效应与非热效应的协同作用。本研究利用海洋生物质资源构建高性能催化剂，解决了传统催化剂成本高、效率低的问题，为印染废水的高效治理提供了经济、环保的解决方案，同时为海洋生物质资源的高值化利用开辟了新途径。
Abstract：Microwave-assisted catalytic degradation technology, owing to its efficiency and controllability, has emerged as a pivotal research area for treating organic pollutants in water. In this study, we innovatively synthesized a Co-Ni@kelp-derived carbon composite(Co-Ni@KC) using kelp as a green carbon source and Prussian blue analogs(CoNi-PBA). Under 800 W microwave irradiation, Co-Ni@KC-3 achieved degradation efficiencies of 99.52%, 99.74%, 94.67%, and 99.69% for methyl orange, methylene blue, crystal violet, and rhodamine B, respectively, at 240 mg/L within 4 minutes, demonstrating excellent cycling stability. The degradation mechanism is attributed to the synergy between thermal and non-thermal effects. By utilizing marine biomass to construct high-performance catalysts, this study addresses the limitations of traditional catalysts, such as high cost and low efficiency, offering an economical and eco-friendly solution for dye wastewater treatment while opening new avenues for the high-value utilization of marine biomass resources.
