Synthesis, characterization and application of Co/Co3O4 nanocomposites as an effective photocatalyst for discoloration of organic dye contaminants in wastewater and antibacterial properties

Specific capacitance behavior of Co‐Co 3 O 4 nanocomposite thin films synthesized via different electrodeposition modes

“…[9][10][11] Also, nanostructured Co 3 O 4 coatings have been found to be useful in other types of applications such electrocatalysts for hydrogen evolution reaction 12 and photocatalysts for discoloration of organic dye contaminants in wastewater and antibacterial treatment. 13 Despite the high theoretical capacitance of Co 3 O 4 , this TMO suffers limited practical utility due to low experimental capacitance values of this material compared to the theoretical value. 14 Studies have shown that the morphology, structure, and dimensions of Co 3 O 4 features are easily tunable by controlling the preparative parameters of the fabrication method employed.…”

Recent Trends and Advances of Co3O4 Nanoparticles in Environmental Remediation of Bacteria in Wastewater

“…In another study, the application of a Co/Co 3 O 4 nanocomposite was applied to the remediation of organic dye in wastewater and the antibacterial effects on B. subtilis , S. aureus , P. aeruginosa , K. pneumonia , and E. coli . Based on the MIC, the nanocomposite was moderately effective against all bacteria, where P. aeruginosa was most susceptible to the nanocomposite [ 51 ]. Mayakannan et al also investigated the antibacterial activities of nickel-doped-Co 3 O 4 nanoparticles.…”

Investigation of co‐electrospun gelatin:TiO2/polycaprolactone:silk fibroin scaffolds for wound healing applications

“…10 Nanotechnologies and nanosciences have been developed in various fields in recent years and helped to create nanoscale components with beneficial properties. [11][12][13][14][15][16][17][18] One of the nano-technologies in tissue engineering is electrospinning. Electrospinning is a popular scaffold fabrication method that can meet many of the wound dressing requirements by creating porous nano-micro fibrous structures that can mimic nature extracellular matrix and provide a favorable microenvironment for cell adhesion and growth.…”
