Fabrication and Investigation of the Magnetic Properties of Co and Co3O4 Nanoparticles
Optics and Photonics Journal
The nanoparticles exhibit some novel optical and magnetic properties, which are different from its bulk material. Cobalt oxide has been known as a semi-conductor compound of p type with a Spinel structure. Therefore, they are used as gas sensor and absorbent of solar energy. Furthermore, they are employed as an effective catalyzer in environmental clearing. In the thermal gradation method, carbonyl cobalt Co2(CO)8 is often used as a precursor, though cobalt carbonyl is very toxic and expensive.doi:10.4236/opj.2016.68b011 fatcat:m7l4u7gq2zcfpdrgce7z2xtpc4
