The role of Cu1–O3 species in single-atom Cu/ZrO2 catalyst for CO2 hydrogenation
Nature Catalysis, 2022 Copper-based catalysts for the hydrogenation of CO2 to methanol have attracted much interest. The complex nature of these catalysts, however, renders the elucidation of their structure–activity properties difficult. Here we report a copper-based catalyst

VAR-tree model based spatio-temporal characterization and prediction of O3 concentration in China.
Ecotoxicology and Environmental Safety, 2023 Ozone (O3) pollution in the atmosphere is getting worse in many cities. In order to improve the accuracy of O3 prediction and obtain the spatial distribution of O3 concentration over a continuous period of time, this paper proposes a VAR-XGBoost model ...

Is O2*(a1Δg) Formed in the O+O3, H+O3, and NO+O3 Reactions ? [PDF]
Bulletin of the Chemical Society of Japan, 1980 Abstract An attempt was made to detect O2*(a1Δg) in the reactions of O+O3, H+O3, and NO+O3 using a photoionization mass spectrometer. No significant signals for O2*(a1Δg) were observed in these reactions. From the results, it is concluded that less than 0.06, 0.001, and 0.002 of the reactive collisions result in the production of O2 ...
