Catalytic decomposition is a promising method for N2O removal, and the nature of active sites on catalysts under debate. The combination experimental observations density functional theory (DFT) calculations indicates that oxygen vacancies in metal oxide serve as decomposition. Co doping CeO2 significantly increases content vacancies, thereby enhancing activity catalyst A with Co/Ce = 1 exhibited best activity, T90 375 °C excellent stability maintained over 100 h, which much better than Co3O4 spinel. finding advances understanding catalytic contributes to design highly efficient catalysts.

Catalysts operating at low temperatures are imperative for the denitrification of flue gases from various non-electric industries. Current catalysts typically exhibit significant activity selective catalytic reduction NOx with NH3 (NH3–SCR) above 100 °C. Here, we observed first time remarkable room-temperature NH3–SCR on surface carbon-based catalysts. The oxidation NO to NO2 by C–O–C groups room temperature serves as a key initial step, triggering fast SCR reaction. C–OH groups, active sites, directly participate in elementary reaction pathways through an H migration process, significantly reducing energy barrier rate-determining step below 1 eV, thereby enabling occur temperature. and its novel mechanism reported this study would inevitably expand research boundaries abatement.

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.
