Abstract

In this work, we reported a method for a fabrication of bead-on-string structured g-C₃N₄/CoFe₂O₄ composite nanofibers by electrospinning coupled with in situ calcination. For the first time, this catalyst effectively removed high concentrations of mixed organic pollutants through the synergistic effects of adsorption and photocatalysis. The composite materials removal efficiency of adsorption and photocatalytic for high concentrations of organic pollutants in wastewater can exceed 90%. Surface potential analysis using in situ Kelvin probe force microscopy demonstrated the electron transfer pathways on the catalyst surface. The formation of the heterojunction was demonstrated through DFT calculations to significantly enhance the efficiency of electron–hole separation. This work provided valuable insights for the development of efficient catalysts for the synergistic adsorption-photocatalytic treatment of environmental pollutants, thus addressing increasingly severe environmental challenges.

g-C3N4/CoFe2O4珠状纳米纤维对多种污染物的高效吸附和催化降解

在这项工作中，我们报道了一种通过静电纺丝耦合原位煅烧制备串珠结构g-C3N4/CoFe2O4复合纳米纤维的方法。该催化剂首次通过吸附和光催化的协同作用，有效去除高浓度的混合有机污染物。复合材料对废水中高浓度有机污染物的吸附和光催化去除效率可达90%以上。利用原位开尔文探针力显微镜进行表面电位分析，证明了催化剂表面的电子转移途径。通过DFT计算证明了异质结的形成，显著提高了电子-空穴分离的效率。这项工作为开发高效的吸附-光催化处理环境污染物的催化剂，从而解决日益严峻的环境挑战提供了有价值的见解。

期刊介绍： Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
