Abstract

Utilizing the surface plasmon effect of metal nanoparticles and constructing effective heterogeneous interfaces are effective strategies for enhancing the photocatalytic performance of semiconductor materials. In this study, a B-N co-doped (A, R)-TiO₂/TiBN heterophase junction-plasma photocatalytic material was successfully prepared through the in situ oxidation phase transformation process of TiBN powder. By controlling the oxidation temperature, the mass ratios of anatase, rutile, and residual TiBN phases were effectively tuned, facilitating the formation of tight interfacial contact between the phases. Residual TiBN acted as localized surface plasmon resonance (LSPR) centers, significantly enhancing light light capture and the separation of photogenerated electron-hole pairs. The results demonstrated that the optimized (A, R)-TiO₂/TiBN-600 catalyst exhibited a remarkably improved photocatalytic hydrogen production rate of 1060.42 μmol g⁻¹ h⁻¹, which is approximately 11 times higher than that of P25. Additionally, the (A, R)-TiO₂/TiBN-600 heterophase junction-plasmonic photocatalyst demonstrated high water evaporation efficiency under simulated sunlight irradiation. This study provides a new engineering strategy for the development of efficient photocatalysts.

（A， R）- TiBN前驱体原位相变制备的tio2 /TiBN异相连接等离子体光催化剂

利用金属纳米粒子的表面等离子体效应和构建有效的非均相界面是提高半导体材料光催化性能的有效策略。本研究通过TiBN粉末的原位氧化相变工艺，成功制备了B-N共掺杂（a， R）-TiO2/TiBN异相结等离子体光催化材料。通过控制氧化温度，可以有效调节锐钛矿、金红石和残余TiBN相的质量比，促进相之间形成紧密的界面接触。残余的TiBN充当局部表面等离子体共振（LSPR）中心，显著增强光捕获和光生电子-空穴对的分离。结果表明，优化后的（A， R）-TiO2/TiBN-600催化剂的光催化产氢速率为1060.42 μmol g−1 h−1，比P25的产氢速率提高了约11倍。此外，（A， R）-TiO2/TiBN-600异相结-等离子体光催化剂在模拟阳光照射下表现出较高的水分蒸发效率。该研究为高效光催化剂的开发提供了新的工程策略。

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
