Accurately sensing the spatial distribution of temperature, one most fundamental parameters, is crucial for understanding mechanism physicochemical process in confined space. However, traditional methods temperature measurement often show a very limited resolution and sensitivity. Herein, we develop surface-enhanced Raman spectroscopy (SERS) nanosensor to measure within hollow carbon nanospheres (HCNSs) study light-promoted Fenton-like catalyzed by Fe single-atom anchored on HCNSs. Based temperature-dependent SERS spectra phenyl isocyanide adsorbed Au nanoparticles, gradient nanocavity surface HCNSs, induced light-irradiation, sensed with sensitivity 0.8 °C. Furthermore, combining local reaction kinetics-temperature relationship, clarify that oxidation phenol peroxymonosulfate occurs at thus providing sound evidence homogeneous mechanism. Besides new strategy submicrometer resolution, this work also shows feasibility through locating reactive site.
