Hierarchical PbO₂ nanoparticles (NPs) were grown by hydrothermal method on TiO₂ nanotubes (NTs) at 3D titanium felt, which is simple and scalable method. TiO₂ NTs were formed on titanium felt by anodising at 25 C in environmentally friendly methanesulphonic acid solution. The growth of PbO₂ on the TiO₂ NTs depended on immersion time during hydrothermal synthesis and followed a LaMer-Dinegar burst kinetic model of nucleation and growth. PbO₂ formation began with rapid nucleation, followed by mesoscale assembly due to organic capping of poly(vinylpyrrolidinone). The electrochemical performance of 3D electrode was recorded in pH 3 sodium sulphate solutions containing Reactive Black 5 (RB-5) azo dye at 25 C. The resulting hierarchical 3D electrode achieved 98% decolourisation after 50 min of anodic oxidation with a first order batch decay rate of 0.0875 min⁻¹.

通过水热法在 3D 钛毡上的 TiO ₂纳米管 (NTs)上生长分层 PbO ₂纳米粒子 (NPs) ，这是一种简单且可扩展的方法。通过在环境友好的甲磺酸溶液中在 25°C 下进行阳极氧化，在钛毡上形成了TiO ₂ NTs。PbO ₂在 TiO ₂ NTs上的生长取决于水热合成过程中的浸泡时间，并遵循成核和生长的 LaMer-Dinegar 爆发动力学模型。氧化铅₂形成开始于快速成核，然后由于聚（乙烯基吡咯烷酮）的有机封端而进行中尺度组装。3D 电极的电化学性能在含有活性黑 5 (RB-5) 偶氮染料的 pH 3 硫酸钠溶液中记录，温度为 25°C。所得分级 3D 电极在阳极氧化 50 分钟后实现了 98% 的脱色，并具有一级批衰减0.0875 min ^{-1 的}速率。
