摘要

受 "以废治废 "低碳方法概念的启发，我们开发了一种将废物吸附剂转化为有效光催化剂的策略。以低成本的稻壳（RHs）为生物模板，通过原位生长和碳化合成了 NiCo2O4@SiO2-RH 复合催化剂。研究了催化剂对四环素（TC）和甲醛（HCHO）降解的影响。在过硫酸盐（PMS）和催化剂的协同作用下，四环素溶液在 45 分钟内降解了 98.9%，并揭示了不同因素对催化性能的影响。此外，所制备的复合催化剂在 1130 秒内完全降解了 22.3 ppm 的甲醛（HCHO）。这项工作为固体废弃物资源再利用提供了一种设计高性能催化材料的可行方案。

Metal-organic framework and rice husk derived NiCo2O4@SiO2-RH composites for catalytic degradation

Inspired by the concept of low-carbon methods to "treat waste with waste", a strategy of tranferring waste adsorbents to effective photocatalysts was developed. Low-cost rice husks (RHs) as biotemplates were employed to synthesize NiCo₂O₄@SiO₂-RH composite catalysts by in-situ growth and carbonization. The effect of catalyst on the degradation of tetracycline (TC) and formaldehyde (HCHO) was studied. Under the synergistic action of peroxymonosulfate (PMS) and catalyst, 98.9 % of TC solution was degraded within 45 min, and the influence of different factors on the catalytic performance was revealed. In addition, the prepared composite catalysts completely degraded 22.3 ppm formaldehyde (HCHO) within 1130 s. This work provides a feasible scheme of designing high-performance catalytic materials for the reuse of solid waste resources.

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
