Summary: The initial exposed facets of Cu2O microcrystals have a direct influence on their structural transformation and product selectivity. The low-index facet tends to maintain its original structure and results in the production of 2-electron transfer products, while the high-index facet undergoes a drastic reconstruction, leading to the formation of C2+ products. This study is of great significance for the preparation and modification of catalyst materials.

Summary: Vertically aligned reduced graphene oxide (rGO) with sulfur and poly(ethylene oxide)-based polymer electrolyte double-shell layers (VRG@S@PPE) enable high-loading sulfur cathode in lithium-sulfur batteries (LSBs). The combination of rGO with vapor-grown carbon fiber (VGCF) allows for gas evacuation without structural collapse, resulting in perfect double-shell layer contact. With the reinforcement of VGCF, sulfur-infiltrated rGO (VRG@S) exhibits high capacity and the addition of an additional polymer electrolyte further improves cycle retention, enabling safe and stable quasi-solid-state LSBs with high sulfur loading.

Summary: Unlike conventional Si anodes, oxidized Si nanosheets, i.e., siloxene, show minimal volume expansion during cycling due to their unique geometries and chemical structures. However, the interactions of siloxene with binders and their effects on charge storage have not been extensively studied. In this study, the intermolecular interactions of siloxene with four typical binders were investigated, and alginate was found to form the strongest intermolecular bonds with siloxene, leading to enhanced cycling stability and rate performance. The alginate-based siloxene electrode exhibited an unprecedented charge capacity retention of 66% after 500 cycles at 200 mA g-1. This study provides valuable insights for designing binders for electrode materials with similar chemical structures to siloxene.
