Reasonable hydrophobic anode is deemed to be a promising electrode for photoelectrocatalytic degradation of wastewater. In this study, the C₃N₄-modified Ti/PbO₂ electrode with tunable hydrophobic characteristics is fabricated by a facile electrodeposition process. It is found that the introduction of C₃N₄ into the PbO₂ films changed the morphology, surface hydrophilicity, and hydrophobicity of the electrode, which promotes the photoelectrochemical active areas, generating efficiency of hydroxyl radicals. In addition, introducing C₃N₄ into PbO₂ coating can enhance oxygen evolution potential and carrier density of PbO₂. Photoelectrocatalytic degradation experiments show that the addition of C₃N₄ can further improve the catalytic performance of PbO₂ and there exists a significant photoelectric synergism in photoelectrocatalytic process. These results demonstrate that the combination of reasonable surface hydrophobic characteristics and photoelectrocatalytic is a prospective approach for wastewater treatment.

合理的疏水性阳极被认为是用于废水的光电催化降解的有前途的电极。在这项研究中，将C ₃ Ñ ₄修饰的钛/的PbO ₂具有可调谐疏水性电极由一个浅显电沉积工艺制造。发现将C ₃ N ₄引入PbO ₂膜中改变了电极的形态，表面亲水性和疏水性，这促进了光电化学活性区域，产生了羟基自由基的效率。另外，将C ₃ N ₄引入PbO _2中涂层可以增强氧释放势和PbO _2的载流子密度。光电催化降解实验表明，添加C ₃ N ₄可以进一步提高PbO ₂的催化性能，并且在光电催化过程中存在明显的光电协同作用。这些结果表明，合理的表面疏水特性和光电催化的结合是废水处理的一种前瞻性方法。
