Synthesis and characte rization o f Cobalt Sulfide Nanostructures via Direct Thermal Decomposition

In the past decade, much effort has been devoted to the synthesis and applic ation of transition metal sulfide nanostructures due to t heir excelle nt electronic, optical and mech anical prope rties and wi de applicatio ns includin g solid lubricants, cataly sts, lithium battery cath odes,scanning probes, photocond uctors and shockwav e resistance materials . Among these materials, cobalt sulfide compounds are especially important because their chemical bonds Co–S have several forces and binding me chanisms th at can form ionic bonds, covalent bonds and metallic bonds which are bound in a molecule. CoS have bee n used to se rve as a low -cost replacement for t he state-of-t he-art EC material RuO۲ in electroc hemical ca pacitors (EC ) and as a negative el ectrode mat erial for rechargeable lithium batteries. So far, various synthesis methods includi ng hydrothermal/solvothermal routes, electrochemical syntheses, wet-chemical methods, colloidal syntheses a nd catalyti c chemical vapor deposition have been succes sfully applied in syntheses of cobalt sulfide nan ostructures [۱-۲].It wa s found that aromatic he terocyclic polymers co ntaining bith iazole rings are good ligands because the two n itrogen ato ms in the bithiazole rin gs are able to chelate m etal ions to form stable five memb er rings. Thi s study dem onstrates th at bithiazole complexe s may be suitable precursors for the preparation of nanoscale materials [ ۳].
