The Natural and H-form of clinoptilolite were subjected to mechanochemical treatment in water and in air. Initial and milled samples were studied using a combination of XRD, FTIR, XPS/UV–vis spectroscopies, SEM and low-temperature nitrogen ad-/desorption. Dry milling leads to the destruction of the crystalline structure, whilst milling in water partially maintains the crystalline structure with a meso- macroporous structure formed in both cases. Surface was enriched with impurity iron, whose oxygen-containing species served as photocatalytic centres. The milled samples exhibit an improved photocatalytic activity in the process of rhodamine B degradation under visible light.

斜发沸石的天然和H型在水中和空气中进行了机械化学处理。使用XRD，FTIR，XPS \ UV-Vis光谱，SEM和低温氮吸附/解吸的组合研究了初始样品和研磨样品。干研磨导致晶体结构的破坏，而在水中研磨则在两种情况下都部分地形成具有中大孔结构的晶体结构。表面富含杂质铁，其含氧物质充当了光催化中心。研磨后的样品在可见光下若丹明B降解过程中表现出改善的光催化活性。
