Within the application landscape of rare‑earth compounds, anhydrous neodymium chloride fulfills multiple roles. Beyond serving as feedstock for neodymium metal and NdFeB permanent magnets, it also holds a vital position in catalysis. It is widely deployed across polymerization reactions for synthetic rubber and visible‑light photocatalysis for wastewater treatment.

First, in synthetic rubber production. Anhydrous neodymium chloride is a key component for manufacturing catalysts used in neodymium‑based styrene‑butadiene rubber, rare‑earth isoprene rubber and other synthetic rubbers. In practical use, it is frequently combined with co‑catalysts such as triethylaluminum to form high‑efficiency catalytic systems for the polymerization of monomers including butadiene and isoprene. Featuring mild operating conditions and stable product performance during rubber processing, such catalytic systems are broadly adopted in downstream sectors such as tires and elastomers.

Next, for photocatalysis. Anhydrous neodymium chloride can modify titanium dioxide photocatalysts, enabling effective degradation of pollutants such as phenols and dyes in wastewater under visible‑light irradiation. Compared with conventional ultraviolet‑driven photocatalysis, visible‑light responsiveness allows the utilization of readily‑available natural daylight or ordinary light sources. It delivers more flexible solutions for industrial wastewater treatment and expands the practical application scope of photocatalytic technologies.

Catalytic systems are generally sensitive to raw‑material quality. Metallic impurities including iron, calcium and sodium introduced into anhydrous neodymium chloride may interfere with catalyst activity and selectivity, thus impairing polymerization performance or degradation efficiency. Accordingly, high purity and consistent batch‑to‑batch quality are prerequisites for repeatable and controllable operation of catalytic systems in catalytic applications.
