Anchoring Pt Particles onto Mesoporousized ZnO Holey Cubes for Triethylamine Detection with Multifaceted Superiorities

Small, Год журнала: 2023, Номер 19(32)

Опубликована: Апрель 20, 2023

Abstract Designing sensing materials with integrating unique spatial structures, functional units, and surface activity is vital to achieve high‐performance gas sensor toward triethylamine (TEA) detection. Herein, a simple spontaneous dissolution used subsequent thermal decomposition strategy fabricate mesoporousized ZnO holey cubes. The squaric acid crucial coordinate Zn 2+ form cubic shape (ZnO‐0) then tailor the inner part open cube simultaneously mesoporousizing left body (ZnO‐72). To enhance performance, mesoporous cubes have been functionalized catalytic Pt nanoparticles, which deliver superior performances including high response, low detection limit, fast response recovery time. Notably, of Pt/ZnO‐72 towards 200 ppm TEA up 535, much higher than those 43 224 for pristine ZnO‐0 ZnO‐72. A synergistic mechanism combining intrinsic merits ZnO, its structure, oxygen vacancies, sensitization effect has proposed significant enhancement in sensing. Our work provides an effective facile approach advanced micro‐nano architecture manipulating active promising sensors.
