Construction of carbon-doped iron-based nanozyme for efficient adsorption and degradation to synergistic removal of aflatoxin B1
The multifunctional composites Fe3O4/GO/NH2-MIL-53(Fe) with excellent adsorption-degradation performance was prepared for the removal of Aflatoxin B1 (AFB1). The adsorption function of Fe3O4/GO/NH2-MIL-53(Fe) was based on the large specific surface area and abundant adsorption sites. The degradation function of Fe3O4/GO/NH2-MIL-53(Fe) was based on the activation of H2O2 by the catalytic active center formed by the coordination of metal ions and oxygen-containing groups in the system, resulting in hydroxyl radicals (·OH), superoxide anion radicals (O2-) and singlet oxygen (1O2). The adsorption of nanozyme accelerated the degradation reaction process, and the adsorption site was further exposed as the degradation process progressed. The synergistic effect realized the efficient removal of AFB1. Construction of Fe3O4/GO/NH2-MIL-53(Fe) as the carbon-doped iron-based nanozyme provided novel approaches of the removal for risks control of AFB1. Accompanied by the AFB1 adsorption, the advanced oxidation of nanozyme to the AFB1 degradation provided a promising way for the synergistic removal of AFB1.
期刊介绍：
Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields.
Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication.
The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
