Abstract 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 and understanding their promoting mechanisms. In this paper, ZIF‐67@MXene nanosheet composites, with conductive in‐plane structure confined‐stable pore/channel, are designed act as high‐efficient achieve significant enhancement the luminol‐H 2 O based system. Mechanism investigation suggests that hydroxyl radicals (·OH) singlet oxygen ( 1 ) can be selectively preferentially generated on due stable absorption of ·OH , leading remarkable efficiency luminol (830%). Finally, by designing plasmonic NH ‐MIL‐88@Pd nanozyme, an “on‐off” switch immunosensor constructed detection prostate‐specific antigen (PSA). Based multiple signal amplification effect, linear range PSA expanded three orders magnitude. The limit also improved from 1.44 × 10 −11 9.1 −13 g mL −1 . This work proposes effective method preparation provides new strategy sensitive cancer markers.
