Summary: In this study, carbon nanofiber flexible films with ultrafine V2O3 nanocrystals uniformly dispersed in the skeleton of nanofibers (V2O3/CNF) were designed and synthesized. The films exhibited excellent potassium storage performance, with outstanding cycling stability (98% retention after 2500 cycles at 1 A g(-1)) and excellent rate capacity (175 mA h g(-1) at 10 A g(-1)). The presence of oxygen-bridged (V-O-C) bonds in the carbon nanofibers provided abundant electrochemically active sites and effectively prevented agglomeration-induced volume expansion.

Summary: We demonstrate that BiOCuCh materials with charged layers can effectively suppress carrier recombination and phonon dissipation. The photogenerated hot carriers are separated by the intrinsic p-n junction and transport at high speed within the two layers. Additionally, interlayer coupling leads to reduced phonon thermalization. As a result, these oxychalcogenides show a significant response to full-spectrum solar light and exhibit cocatalyst-like characteristics. These materials provide a promising platform for exploring materials with extraordinary optoelectric response.
