With the large amount production and application of engineering carbon nanomaterials, their potential ecological risk has attracted extensive attention. The degradation and transformation of the carbon nanomaterials in the environment directly affect the fates and eco-toxicity of the nanomaterials in the environment, and the research of the degradation and transformation processes of the nanomaterials in the environment is the key link for the determination of the environmental capacity of the nanomaterials and for the evaluation of the nanomaterials life cycle in the environment. This paper briefly introduced the chemical transformation, microbial degradation, and photodegradation of the major engineering carbon nanomaterials (carbon nanotubes and fullerene) in the environment, and summarized the environmental and structural factors affecting the degradation of the nanomaterials and the related intrinsic mechanisms. The shortcomings of the related researches and the directions of the future research were also put forward.
随着工程碳纳米材料的大量生产和应用，其潜在的生态风险已引起广泛关注。碳纳米材料在环境中的降解和转化直接影响纳米材料在环境中的归宿和生态毒性，而研究纳米材料在环境中的降解和转化过程是确定纳米材料环境容量以及评估纳米材料在环境中生命周期的关键环节。本文简要介绍了主要工程碳纳米材料（碳纳米管和富勒烯）在环境中的化学转化、微生物降解和光降解，并总结了影响纳米材料降解的环境和结构因素以及相关的内在机制。同时也提出了相关研究的不足及未来研究方向。
