Abstract

The replacement of precious metal electrocatalysts by highly active and cost-efficient alternatives for complete water splitting at low voltage has recently attracted a growing attention. In this work, it is reported how semigraphitized carbons are transformed into highly active electrocatalysts for hydrogen evolution reaction. Moreover, heat treatment at 400 °C under certain conditions can be a simple and cheaper approach to perform surface modification of low-graphitized carbons. This leads to a remarkable modulation on their catalytic activity. These materials can offer promising low-cost catalysts for water decomposition.

碱性电解质中高效，持久的半石墨化碳催化剂

摘要

用高活性和低成本的替代品代替贵金属电催化剂以在低压下完成水的完全分解最近引起了越来越多的关注。在这项工作中，据报道半石墨化的碳如何转化为用于氢释放反应的高活性电催化剂。此外，在一定条件下于400°C进行热处理可能是一种简单且便宜的方法，可以对低石墨化碳进行表面改性。这导致其催化活性的显着调节。这些材料可以为水分解提供有希望的低成本催化剂。
