A porous MoO₃@MoS₂ core-shell nanorod was synthesized by hydrothermal method using MoO₃ nanorods as the precursor. The investigation indicated that at high RhB concentration, MoO₃@MoS₂ nanorod exhibits excellent adsorption ability (Q_max = 326.8 mg/g), while at the low concentration, it exhibits high-performance photocatalytic degradation ability. The adsorption of RhB on MoO₃@MoS₂ nanorod fitted well with pseudo-second-order kinetic model and the adsorption process was mainly controlled by intraparticle diffusion process. The initial fast adsorption process of RhB may localized on both homogeneous (monolayer) and heterogeneous (multilayer) active sites, and then localized on the heterogeneous active sites for the multilayer adsorption matching with the Freundlich isotherm model. The light absorption of MoO₃@MoS₂ nanorod in ultraviolet and visible regions increased significantly due to forming core-shell structure. The results of trapping experiments and EPR analysis showed that in MoO₃@MoS₂ system h⁺ and ·OH play critical roles in the degradation of RhB. Due to forming Z-scheme mechanism, the reducibility of electron in the CB of MoS₂ increases, while the oxidability of hole in the VB of MoO₃ also enhances. Therefore, MoO₃@MoS₂ nanorods display excellent photocatalytic activity under simulated sunlight irradiation, implying promising application in wastewater treatment.

以MoO ₃纳米棒为前驱体，通过水热法合成了多孔MoO ₃ @MoS ₂核壳纳米棒。研究表明，在高RhB浓度下，MoO ₃ @MoS ₂纳米棒表现出优异的吸附能力（Q _max  = 326.8 mg / g），而在低浓度下，表现出高性能的光催化降解能力。RhB在MoO ₃ @MoS ₂上的吸附纳米棒非常适合拟二级动力学模型，吸附过程主要受颗粒内扩散过程控制。RhB的初始快速吸附过程可能既分布在均质（单层）活性位点，又分布在异质（多层）活性位点，然后分布在异质活性位点上，以实现与Freundlich等温模型匹配的多层吸附。由于形成了核-壳结构，MoO ₃ @MoS ₂纳米棒在紫外和可见光区域的光吸收显着增加。诱捕实验和EPR分析的结果表明，在MoO ₃ @MoS ₂系统中h ⁺·OH在RhB的降解中起关键作用。由于形成Z方案机制，MoS ₂的CB中电子的还原性增加，而MoO ₃的VB中的空穴的氧化性也增强。因此，MoO ₃ @MoS ₂纳米棒在模拟阳光照射下显示出优异的光催化活性，这在废水处理中具有广阔的应用前景。
