Summary: In this study, CsPb2Br5 particles were successfully grown on g-C3N4 in an aqueous solution to construct p-n heterojunctions, which improved the photoelectrochemical and photocatalytic performance. The enhancement is attributed to the effective promotion of carrier separation and transfer by p-n heterojunctions, and the use of ligand-free materials that do not hinder charge transfer. The successful synthesis of ligand-free CsPb2Br5/g-C3N4 p-n heterojunction extends the application of perovskite materials in the fields of photoelectrochemistry and photocatalysis.

Summary: Most current redox-type nanozyme-based colorimetric sensing platforms are susceptible to interference from the reductant when using chromogenic probe, and the unstable H2O2 used in the peroxidase-like nanozyme-based systems is prone to difficulty in sensing signal reproducibility, while peroxidase-like nanozyme with oxidase-mimicking activity is easy to bring background interference by O2. Therefore, constructing a COF oxidase-like nanozyme-based controllable sensing system that integrates self-reporting, self-correcting, and light-responsive functions can avoid these affects. The study provides new insights to avoid interference and opens avenues to construct versatile COF nanozyme-based sensors.
