FeWO_(4)结晶釉的取向生长控制及光催化活性研究

Oriented Growth Control and Photocatalytic Activity of FeWO_(4) Crystalline Glazes

具有光催化活性的结晶釉结构对于陶瓷板材表面功能化具有重要的应用价值,但目前功能化表面结晶釉的结构控制及其生长方式对光活性的影响尚不明确。本研究以三氧化钨、硫酸亚铁、磷酸铝、高岭土等为原料,通过调控不同生长取向结构的FeWO_(4)结晶釉,在1080℃成功烧制出高亲核性晶面暴露的结晶釉。结果表明,不同取向的结晶釉釉层呈现不同的晶面暴露,取向生长的结晶釉可以提供更高的催化活性,同时可以促使高亲核性的(100)晶面暴露,从而提高陶瓷板表面的光催化性能。本研究可为光功能化结晶釉材料表面功能化的设计和调控提供理论和实践参考。

The crystalline glaze structure with photocatalytic activity has important application value for the surface functionalization of ceramic panels,but the structure control of functionalized surface crystalline glaze and the influence of its growth mode on photocatalytic activity are still unclear.This study used tungsten trioxide,ferrous sulfate,aluminum phosphate,kaolin,and other raw materials to successfully produce crystalline glazes with exposed high nucleophilic crystal faces by regulating FeWO_(4)with different growth orientation structures at 1080℃.The results indicate that crystalline glaze layers with different orientations exhibit different crystal surface exposures.Crystalline glazes grown with different orientations can provide higher catalytic activity and promote the exposure of highly nucleophilic(100)crystal surfaces,thereby improving the photocatalytic performance of ceramic plate surface.This study can provide theoretical and practical references for the design and regulation of surface functionalization of photo functionalized crystalline glaze materials.
