In this work, sea urchin-like magnetic Fe3O4@CA/BNNS/AgNP composite microspheres were successfully
prepared.
The photocatalytic performance of composite microspheres for the organic
dye rhodamine B (RhB) was systematically investigated under different
conditions, and the catalytic degradation rate of RhB was as high
as 95% within 60 min; after three cycles of recycling, the degradation
rate of RhB was reduced by only 8%. The main active agents in the
reaction are e– and •O2
–. Fe3O4@CA/BNNS/AgNP microspheres
prepared in this study exhibit photocatalytic and electrochemical
properties, making them easy to separate. This work is not limited
to the development of Fe3O4-based catalysts
but also is expected to provide ideas for the research and progress
of photocatalytic composite catalysts with electrochemical properties.
