All data in this work were obtained from the Web of Science database. Keywords searched include “SF6;decomposition;gas sensor;adsorption;DFT;etc.”. After an initial manual screening;a total of 52 research efforts from the past decade (from 2014 to 2024) were selected;focusing on the exploration of gas-sensitive materials for SF6 decomposition products;yielding 250 sets of adsorption data [26];[42] With the help of VOS Viewer software;the collected papers on SF6 decomposition products were clustered and analyzed;and the data were visualized by the keyword co-occurrence mapping module;as shown in Fig. S1 (a);(b) and (c). Fig. S1 (a) presents the changes in the research hotspots related to SF6 decomposition products during the five-year period from 2018 to 2022. Obviously;until 2020;some keywords can be observed;such as ‘decomposition’;‘voltage’;‘characteristic’;‘gas mixture’.
