Furthermore, heat shrinkage is another standard for good solid electrolytes. As shown in Fig.3c, the SiO2-SO3Li/PVDF-HFP reveals hardly any heat shrinkage (about 1%) and maintains its shape stably after being heated at 180 °C for 1 h (Supplementary Fig.9). In contrast, the traditi...
The S-1/TS-1@dendritic-SiO2 material with three-layer core–shell structure was developed and used as the support for Au catalysts, which showed simultaneously fantastic PO formation rate, PO selectivity and stability (over 100 h) for propene epoxidation with H2 and O2. It is found that ...
Full size image X-ray adsorption was employed to explore the chemical state and coordination environment of the Fe atoms in the Fe/SCN. The Fe K-edge X-ray absorption near edge structure (XANES) spectrum of the Fe/SCN is located between that of FeO and Fe2O3(Fig.1e), indicating that...
[27] designed a NiCo2S4/NiO heterostructure cathode catalyst in which the discharge product Li2O2 grows into a large size pea-like shape, endowing the electrode with an extremely high discharge capacity of up to 10,050 mAh g−1 and a tiny overpotential of 0.88 V. Similarly, Yan et al....
Electron transfer between the metal atom and the support can play an important role in tuning the electronic structure, which can influence their activity, selectivity and stability [30]. The second investigation trend is related to the importance of understanding the dynamic behavior of catalytic ...
