As advanced electrochemical catalysts, single‐atom catalysts have made great progress in the field of catalysis and sensing due to their high atomic utilization efficiency and excellent catalytic performance. Herein, stannum‐doped copper oxide (CuOSn1) nanosheets with single‐site SnOCu pairs as active sites are synthesized as electrocatalysts for biological molecule detection. Compared with CuO‐based...
Self‐powered sensing systems (SPSSs) are critical components in smart portable electronic devices. Zinc‐air batteries (ZABs) as promising energy devices provide a great opportunity to develop novel SPSS for sensing applications owing to the merit of high open‐circuit potential. Herein, hierarchically porous single‐atom iridium embedded nitrogen‐doped carbon (SA‐Ir/NC) is reported as an efficient catalyst...
Single‐atom catalysts (SACs) have attracted extensive attention in the catalysis field because of their remarkable catalytic activity, gratifying stability, excellent selectivity, and 100% atom utilization. With atomically dispersed metal active sites, Fe‐N‐C SACs can mimic oxidase by activating O2 into reactive oxygen species, O2−• radicals. Taking advantages of this property, single‐atom nanozymes...
