Thermal Stability and Utilization of 1D-Nanostructured Co3O4 Rods Derived by Simple Solvothermal Processing

For p-type semiconductor nanoparticles, such as the cobalt oxide spinel, enhancing nanoparticle geometry can expose more of surface and bring up sensitivity applicability, pointing to even advantageous behaviour in comparison n-type semiconductors which are known for a somewhat faster reactivity. Here, we present strategy that relies on fostering simple synthetic route deliver reasonably or comparably performing p-type-semiconducting partially 1D-Co3O4 material prepared under less technically economically demanding conditions. Structurally monophasic Co3O4 nanoparticles with spinel structure were indicated by powder X-ray diffraction, while presence traces organic-phase residuals otherwise chemically homogeneous was observed Fourier-transform infrared spectroscopy. Scanning electron microscopy further showed fine matter formed agglomerates possible rod-like formations. Interestingly, using transmission microscopy, it reveal nanoparticulated actually nanostructured, i.e., 1D-shaped rods embedded matrix confirmed. In conjunction N2 adsorption–desorption isotherms, discussion about orientation, exposure nanostructured rod domains, derivative parameters possible. The shown be stable 800 °C whereat decomposition CoO takes place. specific area sample raised. purpose testing photoactivity samples, sorption/photodegradation tests methylene blue model pollutant performed. degradation performance better described pseudo-second-order fit, suggesting is worth development toward improved immobilized photocatalysts.
