Abstract
En 中文
The integration of high electrical conductivity, structural robustness, and scalable processability in one-dimensional oxide nanomaterials remains a pivotal challenge for their deployment in next-generation electronics and energy devices. Here, we report a rational synthesis of strontium vanadate nanofibers by decoupling morphological formation from electronic structure control. A hydrothermal step produces high-aspect-ratio nanofibers, while subsequent hydrogen reduction precisely engineers their electronic state. This synergistic approach yields exceptional charge transport properties: a room-temperature conductivity of 4386 S cm⁻1 and a high Hall mobility of 813 cm2 V⁻1 s⁻1. Conductive atomic force microscopy further confirms highly efficient interfacial charge injection. Consequently, these engineered nanofibers demonstrate promise as a versatile platform, preliminarily validated in transparent conductive films, electrocatalysis, and lithium-ion battery anodes. This work transcends a single-material study, presenting a generalizable processing-structure-property framework for endowing oxide nanomaterials with tailored high conductivity, thereby opening avenues for their integration into advanced multifunctional devices.
