Abstract:

Collagen-derived carbon has many advantages, such as wide source of raw materials, low cost, adjustable porous structure, excellent conductivity, high defect density and rich heteroatom doping. The research status of collagen-derived carbon at home and abroad is reviewed in this paper. The commonly used precursor materials, such as shrimp shell, fish scale, crab shell, oyster shell, animal skeleton and animal skin, are summarized. And then, the effects of different activation and modification methods, including calcium carbonate/hydroxylapatite self-activation, synergy activation of hydroxylapatite/calcium carbonate and KOH, potassium compound-assistant synthesis, on pore structure and chemical functional groups of collagen-derived carbon are analysed and compared. Additionally, the application of collagen-derived carbon in water treatment, involving adsorption and catalysis, is emphatically analysed. Finally, in view of the problems in the water treatment process, the corresponding countermeasures and the development trend are prospected, which could provide the theoretical basis for the application of collagen-derived carbon in practical wastewater treatment.

Key words: collagen, biochar, adsorption, catalysis

摘要:

胶原基衍生炭具有原料来源广泛、成本低廉、孔结构可调、导电性能优异、缺陷密度高和多原子掺杂等优点,在水处理领域展现出巨大的发展潜力。本文回顾了胶原基衍生炭在国内外的研究现状;对目前常用的前体材料,包括虾壳、鱼鳞、蟹壳、牡蛎壳、动物骨骼和动物皮等进行归纳总结;并就不同的活化与改性工艺,包括碳酸钙或羟基磷灰石自活化法、羟基磷灰石(或碳酸钙)和KOH协同活化法、钾化合物辅助法等,对调控孔隙结构和表面官能团等方面的影响进行了分析比较;重点探讨了其在吸附与催化氧化等水处理领域中的应用。最后,针对水处理过程中存在的问题,提出了相应的对策措施并展望了发展趋势,以期为胶原基衍生炭在实际废水处理中的应用提供理论依据。
