As a catalyst, niobium chloride plays an important role in organic synthesis. Most of the reactions catalyzed by niobium chloride have reaction strips. In addition, pentachloride has the advantages of mild, short time, high yield, less catalyst consumption, simple operation,

Nano-zero-valent iron (nZVI) refers to Fe particles with a particle size of 1-100 nm and a specific surface area of 10-70 m2/g. It has high catalytic performance and reaction activity. Researchers have found that zero-valent iron has good environmental friendliness
