摘要

本文以3d打印的Ti6Al4V钛合金结构为原料，通过阳极氧化工艺合成了TiO2纳米管。阳极氧化是在平面和开放晶格三维结构上进行的。采用平板样品研究了阳极氧化时间对光催化效率的影响，重点研究了在紫外线和模拟阳光下对亚甲基蓝的降解。确定了最佳阳极氧化时间为15分钟，并随后将其应用于三维结构以评估形状的影响。在涉及旋转运动的动态条件下，对这些复杂的3D结构进行了进一步的光催化评估，与静态条件相比，其光催化性能得到了增强。这些发现突出了3d打印技术与定制阳极氧化工艺相结合在增强tio2基材料旋转光催化性能方面的有效性，在环境修复和先进技术方面具有潜在的应用前景。

Rotating photocatalytic activity of TiO2 nanotubes grown on 3D-printed titanium alloy structures

Herein, TiO₂ nanotubes are synthesised from 3D-printed Ti6Al4V titanium alloy structures via an anodization process. Anodization is performed on both flat and open lattice 3D structures. The effect of anodization duration on the photocatalytic efficiency is investigated using flat samples, focusing on the degradation of methylene blue under ultraviolet (UV) and simulated sunlight. An optimal anodization time of 15 min is identified and subsequently applied to the 3D structures to evaluate the effect of shape. Further photocatalytic assessments are conducted on these complex 3D structures under dynamic conditions involving rotational movements, which demonstrate enhanced photocatalytic performance compared to static conditions. These findings highlight the effectiveness of combining 3D-printing technology with tailored anodization processes in enhancing the rotating photocatalytic properties of TiO₂-based materials, with potential applications in environmental remediation and advanced technologies.

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
