A simple method to fabricate edge-oriented MoS2 films with sponge-like morphologies is demonstrated. They are directly fabricated through the reaction of sulfur vapor with anodically formed Mo oxide sponge-like films on flexible Mo substrates. The edge-oriented MoS2 film delivers excellent hydrogen evolution reaction (HER) activity with enhanced kinetics and long-term cycling stability. The material also has superior energy-storage performance when working as a flexible, all-solid-state supercapacitor device.
本文展示了一种简单的方法来制备具有海绵状形态的边缘取向的 MoS2 薄膜。它们是通过将硫蒸气与在柔性 Mo 基底上形成的阳极氧化 Mo 氧化物海绵状薄膜反应直接制备的。边缘取向的 MoS2 薄膜具有出色的析氢反应 (HER) 活性，具有增强的动力学和长期循环稳定性。当用作柔性全固态超级电容器器件时，该材料还具有优异的储能性能。
