“…However, its wide-band-gap energy (3.2 eV) limits its use to photocatalysis, as pure TiO 2 exhibits low conductivity and limited reactivity for electrochemical BPA detection. Modified TiO 2 materials, such as facet-tailored, noble metal surface-loaded, and oxygen vacancy-engineered composites, demonstrate improved electrochemical performance. , These modifications offer opportunities in catalysis and device design, controlling optical and electrical properties. − Therefore, to address the low conductivity and lack of active sites of TiO 2 , development and exploration of highly active and selective TiO 2 electrode are required. , …”

Exploring novel electrochemiluminescence (ECL) co‐reaction accelerators to construct ultrasensitive sensing systems is a prominent focus for developing advanced ECL sensors. However, challenges still remain in finding highly efficient accelerators and understanding their promoting mechanisms. In this paper, ZIF‐67@MXene nanosheet composites, with highly conductive in‐plane structure and confined‐stable pore/channel, are designed to act as high‐efficient co‐reaction accelerators and achieve a significant enhancement in the luminol‐H2O2 based ECL system. Mechanism investigation suggests that hydroxyl radicals (·OH) and singlet oxygen (1O2) can be selectively and preferentially generated on ZIF‐67@MXene due to the stable and efficient absorption of ·OH and 1O2, leading to a remarkable enhancement in the ECL efficiency of luminol (830%). Finally, by designing a plasmonic NH2‐MIL‐88@Pd nanozyme, an “on‐off” switch immunosensor is constructed for the detection of prostate‐specific antigen (PSA). Based on the multiple signal amplification effect, the linear detection range for PSA is expanded by three orders of magnitude. The detection limit is also improved from 1.44 × 10−11 to 9.1 × 10−13 g mL−1. This work proposes an effective method for the preparation of highly efficient co‐reaction accelerators and provides a new strategy for the sensitive detection of cancer markers.
