Hydrothermal synthesis of Co3O4 with different morphology: Investigation of magnetic and electrochemical properties

Recent advances in hydrothermally and solvothermally grown Co3O4 nanostructures for electrochemical energy storage (EES) applications: a brief review

“…The electrochemical activity examined by CV confirmed that the charge is stored with a reversible faradaic redox reaction process and all samples exhibited pseudocapacitive behavior. 152 Later, Umar et al . developed and studied the supercapacitor characteristics of perforated Co 3 O 4 nanosheets using HMT.…”

“…The electrochemical activity examined by CV confirmed that the charge is stored with a reversible faradaic redox reaction process and all samples exhibited pseudocapacitive behavior. 152 Later, Umar et al developed and studied the supercapacitor characteristics of perforated Co 3 O 4 nanosheets using HMT. Interestingly, HMT accomplishes two important roles here: first, it forms a stable chelate complex with metal ions while acting as a chelating agent, and secondly, as a hydrolyzing agent, it hydrolyzes to release OH À ions and helps in the formation of metal hydroxides.…”

Synthesis and Characterization of Cobalt Oxide Nanostructures. a Brief Review

“…They reported that the value of saturation magnetization was higher for high concentration NaOH synthesized Co 3 O 4 nanoparticles than lower one, while opposite behavior was observed for NH 4 OH precipitant. N.K.Yetim [92] reported that the magnetic properties of Co 3 O 4 nanostructures manufactured by the hydrothermal method using different precipitating agents. The results revealed that the hysteresis curve was observed only for nanosheets-like Co 3 O 4 structures synthesized using urea.…”

Sustainable Hydrothermal and Solvothermal Synthetic Approaches for Advanced Carbon Materials in Multidimensional Applications: A Review

“…Hydrothermal synthesis of materials will have the reactants or carbon source dispersed in water prior to the carbonisation under high temperatures and pressures. The benefits of this method include ease of synthesis, ease of composition control, and thus controlling the resulting particle properties such as high surface area, size, shape, and dispersion [12,13]. The advantages of these high temperature and high pressure (HTHP) methods of synthesis, also include thermal and chemical stability, and thus, mitigate the metal dissolution/leaching when metals are used as dopants to carbon [14].…”
