摘要

本研究介绍了一种新颖的方法，用于制造含有正交 Ag2CrO4 异质结的稳定、高性能 TiO2 纳米管，旨在推进多功能应用。利用 XRD、FTIR、UV-DRS、SEM、TEM、PL 和 XPS 等技术进行的综合表征揭示了材料的结构、光学和电化学特性。由此产生的复合材料表现出独特的 1 型异质结机制，增强了电荷分离和转移，提高了其在各种应用中的功能。在光催化方面，该材料具有更强的光吸收能力，可在 180 分钟内完全降解有机污染物。此外，它还表现出卓越的电化学性能，特别是在亚硝酸盐传感方面，其检测限为 1.04 μM。这项工作强调了具有正交 Ag2CrO4 异质结的 TiO2 纳米管作为环境修复、低浓度分析物检测和生物医学应用的可持续高效解决方案的潜力。

Type-1 heterojunction TiO2 Nanotubes/Ag2CrO4 nanoparticles: Advanced photocatalytic and electrochemical applications

This study introduces a novel methodology for fabricating stable, high-performance TiO₂ nanotubes incorporated with orthorhombic Ag₂CrO₄ heterojunctions, aimed at advancing multifunctional applications. Comprehensive characterization using techniques such as XRD, FTIR, UV-DRS, SEM, TEM, PL, and XPS reveals the structural, optical, and electrochemical properties of the material. The resulting composite exhibits a unique Type-1 heterojunction mechanism that enhances charge separation and transfer, improving its functionality across diverse applications. In photocatalysis, the material demonstrates extended light absorption, achieving complete degradation of organic pollutants within 180 min. Additionally, it exhibits remarkable electrochemical performance, particularly in nitrite sensing, with a detection limit of 1.04 μM. This work underscores the potential of TiO₂ nanotubes with orthorhombic Ag₂CrO₄ heterojunctions as a sustainable and efficient solution for environmental remediation, low-level analyte detection, and biomedical applications.
