This work continues EPR investigation of photocatalytic systems based on vanadium modified titanium dioxide (anatase) surface containing various concentrations of VO²⁺ paramagnetic centers (PCs). Three different types of the isolated PCs are revealed on the surface of V–TiO₂ nanoparticles and quantitatively characterized. Time-dependent transitions among these PCs were observed and kinetic behavior was described using new theoretical approach and the developed numerical calculation procedure. The slow-process kinetic rate constant has been calculated from EPR data.

对TiO 2（锐钛矿）表面吸附的钒基络合物的结构和动力学的精细分析：EPR研究

这项工作继续对基于钒改性的二氧化钛（锐钛矿）表面的光催化系统进行EPR研究，该表面包含各种浓度的VO ²⁺顺磁性中心（PC）。在V–TiO ₂纳米颗粒的表面上发现了三种不同类型的分离PC，并对它们进行了定量表征。观察到这些PC之间的时间依赖性转变，并使用新的理论方法和发达的数值计算程序描述了动力学行为。慢速动力学速率常数已根据EPR数据计算得出。
