Applications of CuO Nanoparticles

CuO first attracted the attention of chemists as a suitable catalyst in organic reactions but recently discovered applications of CuO, such as high-Tc superconductors, gas sensors, solar cells, emitters, and electronic cathode materials, also make this material a hot topic for physicists and materials science engineers. Some of the most exciting applications of CuO nanomaterials are sensing, photocatalyst, and supercapacitor, which will be highlighted in this section. It is surface conductivity that makes CuO an ideal material for semiconductor resistive gas sensor applications, and in fact, CuO nanomaterials were used for the detection of many different compounds such as CO, hydrogen cyanide, and glucose. As sensing properties closely relate to the chemical reaction on the sensor's surface, the specific area is a critical factor in achieving high sensitivity sensor. Due to the increased surface area/volume ratio, the sensing property of CuO nanomaterials was enhanced significantly. The shape of CuO nanostructures was also believed to affect significantly the sensing properties of CuO nanomaterial; for example, spherical crystals often show higher sensitivity than columnar ones. Aslani and Oroojpour[4] studied the CO-sensing properties of different CuO nanoparticles prepared by the solvothermal route as a function of the morphology and size of nanoparticles. The results show that cloud-like structures with high surface area/volume have higher response and detection limits than other morphologies. Yang et al. It also showed that the specific surface area of these CuO nanostructures plays an essential role in the sensitivity for detecting HCN.
