One-Pot Fabrication of g‑C3N4/MWCNTs Nanocomposites with Superior Visible-Light Photocatalytic Performance
journal contribution
posted on 2019-02-19, 00:00 authored by Fei Ding, Zhanfeng Zhao, Dong Yang, Xuyang Zhao, Yao Chen, Zhongyi JiangVisible-light photocatalysis has
drawn tremendous attention in
the field of chemical industry owing to its considerable significance
in pollution abatement and energy supply. Herein, graphitic carbon
nitride/multiwalled carbon nanotubes (g-C3N4/MWCNTs) nanocomposites are fabricated using a melamine–cyanuric
acid supramolecular assembly as precursor via a facile one-pot method.
On one hand, the stable covalent connection between g-C3N4 and MWCNTs is built during the self-assembling process
of the supramolecular precursor, which intensifies catalytic and adsorption
abilities. On the other hand, MWCNTs confer both active sites and
a radially single-track electron transfer path, which is conducive
to restraining the combination of photogenerated carriers. The g-C3N4/MWCNTs nanocomposite with the optimal MWCNTs
content can completely degrade rhodamine B (RhB) solution within 1
h, and the degradation rate is improved ∼6.6 times compared
with pure g-C3N4. This facile strategy for fabricating
efficient and stable visible-light-driven photocatalysts may hold
great promise in large-scale water treatment.
