12016-80-7 | Cobalt Oxyhydroxide (CoOOH)

Chemical type

• Transition metal oxyhydroxide
• Oxidized form of cobalt hydroxide
• Redox-active inorganic solid

^[1]

• Metal oxyhydroxide catalyst

^[2]

Key properties

• Higher thermal and structural stability than Co(OH)₂
• Reduced local structural disorder
• Shorter Co–O and Co–Co bond lengths
• Improved mechanical strength against Zn²⁺ intercalation
• Higher cobalt oxidation state

^[1]

• Abundant surface hydroxyl groups
• High number of active sites
• Excellent electron transport properties
• Prone to agglomeration and cobalt ion leaching
• Facilitates Co²⁺/Co³⁺ redox cycling

^[2]

• Cathode material for aqueous zinc-ion batteries
• Structural stabilizer in mixed-phase Co(OH)₂/CoOOH electrodes
• Active redox component in battery charge–discharge processes

^[1]

• Activator for peroxymonosulfate (PMS) in sulfate radical-based advanced oxidation processes (SR-AOPs)
• Degradation of organic pollutants like dyes (e.g., rhodamine B, 2,4-dichlorophenol)

^[2]

Classification by use

• Chemicals used as battery cathode materials
• Chemicals used to enhance cycling stability in energy storage
• Chemicals used in electrochemical redox systems

^[1]
