“…Figure f displays the Mott–Schottky plots that were acquired at different frequencies (500, 700, and 1000 Hz). The flat-band potential is −0.75 V relative to the Ag/AgCl electrode . This value is the same as −0.55 V in relation to the normal hydrogen electrode (NHE, pH = 6.8).…”

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.

Constructing a novel photocatalyst to realize both pollutant oxidation and evolved CO2 reduction in one photoredox cycle can significantly reframe the role of pollutant management. Here, self‐floating poly(bismaleimide‐co‐divinylbenzene) porous microspheres (PBMs) are filled with ZnSnO3 quantum dots (ZSO QDs) to construct a polymer composite microreactor with an S‐scheme heterojunction (ZSO QDs/AP‐PBMs). This microreactor realizes efficient catalytic oxidation and degradation of antibiotic pollutants under light, and the CO2 generated in this process is reduced to high value‐added CO, allowing for the direct conversion of pollutants to a resource in one photoredox cycle. The high specific surface area of the PBMs enables the rapid and efficient adsorption of levofloxacin (LVX), and the self‐floating porous design effectively solves the problem of CO2 adsorption and mass transfer in the gas–liquid–solid three‐phase system, while the S‐scheme heterostructure enhances charge carrier separation. As a result, ZSO QDs/AP‐PBMs achieves complete degradation of LVX in one redox cycle with 100% selectivity to produce 100.3 µmol g−1 CO, and further draw a conclusion that fluoroquinones antibiotics as excellent electron donors can significantly enhance co‐catalytic effect with CO2, which is not previously reported. Theoretical calculations and characterization experiments provide information on S‐scheme heterojunction transfer mechanism and possible degradation pathways, allowing for the rational design of photoredox bifunctional catalysts.
