AB  - Chemical co-precipitation synthesis was used to make pure and zirconium-doped cobalt 
sulfide (Co3S4) nanoparticles (NPs). Important characterizations such as FTIR, UV-VIS, 
Raman, PL, SEM, XRD, and four probe methods were used to examine the influence of the 
Zr (0%, 5%, 10%, 15%, and 20%) doping on optical, electrical, structural, and 
thermoelectric characteristics of Co<sub>3</sub>S<sub>4</sub> NPs. X-ray diffraction and SEM examination 
verified the cubic structure and grain size of pure and Zr-doped Co<sub>3</sub>S<sub>4</sub>-NPs. The FTIR 
spectrum revealed the rotational and vibrational modes linked to the material's surface. The 
material is optimal for photocatalytic activity with a redshift in the band gap value (Eg) as 
a function of Zr dopant and exhibit very good absorbance in the optical region. Raman and 
PL spectroscopy examined the vibrational modes, optical and electrical properties of the 
prepared samples. The measurement of the thermoelectric effect showed that all samples 
approached the critical value of the temperature where the current started decreasing.
