Outside front cover image: In the field of catalysis, the intentional introduction of defects is an advanced material design strategy. In this work, plasma functionalized defective MoSe2 is prepared for electrochemical sensing of H2O2. The tailored Se vacancies and N dopants generate new active sites, expose more edge active surfaces, narrow the bandgap, and strengthen binding with •OH. The sensor delivers competitive sensing performance in an ultra-wide pH range and a portable SPE sensor is developed to demonstrate the significant commercial potential. This work provides insights into plasma surface modification of 2D catalytic materials. (DOI: 10.1002/smm2.1089)
