Ti/TiN/PbO₂ electrodes were prepared using an arc-sprayed TiN interlayer on Ti substrates, followed by the anodic electrodeposition of a PbO₂ catalytic surface layer on it. In order to investigate the positive effect of the TiN interlayer on the stability and electrocatalytic activity of the anodes, microstructural, surface roughness, adhesion evaluation, accelerated life and electrochemical performance tests and electrooxidation experiments of phenol simulated wastewater were conducted and compared with Ti/PbO₂ anodes without the interlayer. The experimental results demonstrated that the arc-sprayed TiN interlayer with a thickness of 140–180 μm had a higher surface roughness and hardness than that of its titanium substrate. The coatings forming the electrode were firmly bonded to the substrate. The conductivity of the Ti-based PbO₂ anode containing the TiN interlayer was significantly improved. The PbO₂ surface coating achieved a faster deposition rate and finer grains, which produce a number of anode active sites and the electrocatalytic performance was boosted with a removal rate of phenol of up to 85.2%, which was higher than that of Ti/PbO₂ by 30.6%. Simultaneously, the anode stability was also significantly enhanced, i.e., the Ti/TiN/PbO₂ anode constructed by introducing the TiN interlayer exhibited excellent stability and electrocatalytic performance. The high-performance anode obtained relied not only on the presence of the arc-sprayed TiN interlayer, which significantly improved the overall physicochemical properties of the electrode, but also on the kinetic rate of the electrocrystallization growth of the refined PbO₂ coating that was accelerated.

Ti/TiN/PbO ₂电极使用电弧喷涂TiN 夹层在Ti 基材上制备，然后在其上阳极电沉积PbO ₂催化表面层。为了研究 TiN 夹层对阳极稳定性和电催化活性的积极影响，进行了苯酚模拟废水的微观结构、表面粗糙度、附着力评估、加速寿命和电化学性能测试以及电氧化实验，并与 Ti/PbO 进行了比较。₂没有夹层的阳极。实验结果表明，电弧喷涂厚度为 140-180 μm 的 TiN 夹层比其钛基体具有更高的表面粗糙度和硬度。形成电极的涂层牢固地结合到基材上。含有TiN中间层的Ti基PbO ₂阳极的导电性得到显着提高。PbO ₂表面涂层实现了更快的沉积速率和更细的晶粒，产生了许多阳极活性位点，电催化性能得到提升，苯酚去除率高达 85.2%，高于 Ti/PbO ₂ 30.6%。同时，阳极稳定性也显着提高，即 Ti/TiN/PbO ₂通过引入 TiN 中间层构建的阳极表现出优异的稳定性和电催化性能。获得的高性能阳极不仅依赖于电弧喷涂 TiN 夹层的存在，显着改善了电极的整体物理化学性能，而且还依赖于加速精制 PbO ₂涂层电结晶生长的动力学速率.
