摘要

近年来，人们对碱性条件下氧进化反应（OER）电催化剂的新材料进行了深入研究，以推动水分离技术的发展。然而，缺乏稳定性和使用贵金属作为电催化剂等问题仍有待解决。在本研究中，我们报告了一系列黑钨矿钨基材料（MWO4，M = Fe、Mn、Ni、Co）的合成及其在碱性条件下对 OER 的电催化特性。我们的研究结果表明，Ni0.5Mn0.5WO4 是一种很有前途的电催化剂，它易于制备，在实验过程中非常稳定，其 OER 活性与标准氧化铱相当。这项研究凸显了黑钨矿钨基材料作为一类新型碱性条件下 OER 电催化剂的潜力。

Efficient Electrocatalysts for Alkaline Oxygen Evolution Reaction from Wolframite Derived Heteroatom Materials

New materials for oxygen evolution reaction (OER) electrocatalysts in alkaline conditions have been highly investigated in recent years for the advancement of water splitting. However, questions such as the lack of stability and the use of noble metals as electrocatalysts still need to be addressed. In this study, we report the synthesis and electrocatalytic properties of a series of wolframite tungsten-based materials (MWO₄, M=Fe, Mn, Ni, Co) towards OER in basic conditions. Our results showed that Ni_0.5Mn_0.5WO₄ is a promising electrocatalyst, exhibiting ease of preparation, stability over the course of our experiments, and OER activity comparable to the standard iridium oxide. This study highlights the potential of wolframite tungsten-based materials as a new class of electrocatalysts for OER in alkaline conditions.
