Abstract:

Biomass-based@CuNiOS composite catalysts with easy recyclability, efficient water separability, and biodegradability were prepared via a hydrothermal synthesis method. The catalytic performance and reusability of the catalyst were evaluated using methylene blue (MB) and rhodamine B (RhB) as model pollutants. The results showed that the NZ@CuNiOS, NP@CuNiOS, and NB@CuNiOS completely reduced MB within 8min, 16min, and 12min, respectively, and RhB within 26min, 34min, and 32min. In contrast, delignification significantly enhanced the catalytic efficiency. DZ@CuNiOS, DP@CuNiOS, and DB@CuNiOS required only 4min, 8min, and 6min for the complete reduction of MB and 18min, 26min, and 24min for RhB reduction, demonstrating excellent catalytic activity. Moreover, the biomass-based@CuNiOS composite catalysts retained over 84% reduction efficiency after multiple cycles, indicating excellent reusability. The catalysts, featuring environmental friendliness, rapid recovery, high catalytic efficiency and biodegradability, offer a promising strategy for sustainable pollution remediation.

摘要:

采用水热合成法制备了一种便于回收、易于与水分离且可生物降解的生物质基@CuNiOS复合催化剂,并以亚甲基蓝(MB)和罗丹明B(RhB)为模型污染物评估了其催化活性及重复使用性等性能。研究结果表明,以天然木/竹材为基底的NZ@CuNiOS、NP@CuNiOS和NB@CuNiOS分别于8min、16min和12min内完全还原MB,26min、34min和32min内完全还原RhB。相比之下,脱木素处理显著增强了催化剂的催化效率,DZ@CuNiOS、DP@CuNiOS和DB@CuNiOS仅需4min、8min和6min即可完全还原MB,在18min、26min和24min内完全还原RhB,展现出优异的催化活性。此外,生物质基@CuNiOS复合催化剂多次使用后仍保持84%以上的还原效率,展现出良好的重复使用性。该催化剂不仅绿色环保、可快速回收,而且性能优异以及具有可降解特性,为可持续污染治理提供了新思路。
