In this work, highly ordered macro-mesoporous TiO₂ has been successfully synthesized using fresh rose petals and P123 (EO₂₀PO₇₀EO₂₀) as dual templates through a simple soaking and calcining process. Characterization of the as-prepared TiO₂ indicated that the mesoporous structure of the TiO₂ was highly ordered, with a pore diameter of approximately 3 nm. After electrodeposition of Pt nanoparticles onto the TiO₂ as an electron transfer enhancer and the immobilization of horseradish peroxidase (HRP) onto the TiO₂-modified electrode, a biosensor for detecting hydrogen peroxide (H₂O₂) was realized. This biosensor showed a wide linear detection range from 5 μM to 8 mM and a low detection limit of 1.65 μM with good stability and high selectivity, suggesting that the sensor is well-suited for the detection of H₂O₂.

在这项工作中，已经成功地使用新鲜的玫瑰花瓣和P123（EO ₂₀ PO ₇₀ EO ₂₀）作为双重模板，通过简单的浸泡和煅烧过程成功合成了高度有序的大介孔TiO ₂。的表征所制备的TiO ₂表示，TiO 2的介孔结构₂被高度有序，具有大约3nm的孔直径。的Pt纳米颗粒的电沉积在TiO后₂作为电子传递增强剂和辣根过氧化物酶（HRP）的固定化到所述的TiO ₂改性的电极，用于检测氢的生物传感器过氧化物（H ₂ ö ₂）已实现。该生物传感器显示了从5μM到8 mM的宽线性检测范围和1.65μM的低检测限，具有良好的稳定性和高选择性，表明该传感器非常适合于H ₂ O ₂的检测。
