Anodic water splitting is driven by hydroxide (OH–) adsorption on the catalyst surface and consequent O2 desorption. In this work, various heteroatoms (S/N/B/P) with different electronegativities oxophilicities are introduced to alter catalytic activity of reduced graphene oxide (RGO) as a for oxygen evolution reaction (OER). It found that, surprisingly, S-doped RGO outperforms other RGOs doped more electropositive or electronegative oxophilic heteroatoms, effect becomes prominent after Fe...
Abstract LiNiO 2 remains a target for layered oxide Li‐ion cathode development as it can theoretically deliver the highest energy density of this materials class. In practice, suffers from poor capacity retention due to electrochemically‐induced structural changes. While impact Ni off‐stoichiometry on electrochemical performance has been extensively studied, that planar defects present in as‐synthesized is not well understood. Advanced ex situ and operando structure probes are used identify...
Improving the room temperature ionic conductivity of solid-state polymer electrolytes for lithium batteries is a big challenge. Exploring new composite one important solutions. Herein, inorganic two-dimensional layered metal boride nanomaterial (MBene) was first applied to electrolyte. The hyperbranched cross-linking electrolyte prepared by free radical polymerization double bond modified MBene and ether with bonds in presence PVDF-HFP salt. c provided material characteristics adsorbing salt...
Weberite-type sodium transition metal fluorides (Na2M2+M'3+F7) have emerged as potential high-performance intercalation cathodes, with predicted energy densities in the 600-800 W h/kg range and fast Na-ion transport. One of few weberites that been electrochemically tested is Na2Fe2F7, yet inconsistencies its reported structure electrochemical properties hampered establishment clear structure-property relationships. In this study, we reconcile structural characteristics behavior using a...
Metal-organic frameworks (MOFs) are considered as promising catalytic materials for electrochemical carbon dioxide reduction (ECR) reactions due to their excellent properties. However, the development of efficient and stable electrocatalysts within a wide potential window remains great challenge. Herein, rod-like Sn-MOF is synthesized by fast simple solution reaction, which has good performance in converting CO 2 HCOOH. In particular, reaches maximum Faradaic efficiency 86.4% at −1.15 V vs...
Electrochemical CO 2 reduction (ECR) has received significant attention with the rising emphasis on renewable energy. However, high Faradaic efficiency (FE), big current density and product selectivity are still challenge for ECR. Selecting ionic liquids (ILs) as electrolytes ECR advantages of enhancing improving density. Herein, in situ shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) is employed first time to study process nickel foam (NF) imidazolium ILs. Results show...

Both CdSe CdS used as sensitizer QDSSC each them has its demerits merits, but low if they were respectively. Thus, order overcome their respectively, we could try combine merits. technique problems cell. But before large-scale application...
With the present materials supply crunch caused by burgeoning Li-ion battery-based electric vehicle market, more sustainable battery chemistries are needed. When considering possible chemistries, sodium (Na) and iron (Fe) stand out as promising candidates for intercalant ions redox centers, respectively. Recently, weberite-type metal fluorides (Na 2 M 2+ Mʹ 3+ F 7 ) have emerged potential high performance Na cathode 1-4 with predicted energy densities in 600 to 800 Wh/kg range (higher than...
