Within the broad field of transition metal compounds, ferrous tungstate (FeWO?) stands out as a representative example of an iron-group element combined with tungstate, gaining prominence in chemical and materials science research due to its unique physicochemical properties and versatile application potential. This tungstate, formed by Fe2? and (WO?)2?, not only inherits the magnetic commonality of iron-group elements but also exhibits rich functional characteristics due to the introduction of the tungsten-oxygen framework, opening new pathways in catalysis, energy storage, and…
