General description

Cobalt(II) acetate tetrahydrate is a pink to red crystal that dissolves well in water. It acts as a catalyst to speed up chemical reactions like oxidation and esterification in making medicines and fine chemicals.It helps in electroplating to add strong cobalt layers on metals for cars and planes, fighting rust better. It also makes bright cobalt pigments for paints, ceramics, and plastics. Our offering features ICobalt(II) acetate tetrahydrate at ≥99.9% trace metals purity, making it particularly suitable for the synthesis of forthe use as a high-performance catalyst in R&D applications.

Application

Cobalt(II) acetate tetrahydrate is a reliable cobalt precursor for fabricating advanced cobalt-based catalysts. For instance, it enables synthesis of cobalt-vacant Co₃O₄, a stable catalyst for room-temperature ozone decomposition in humid air. This versatile compound excels in industrial catalysis, including petroleum refining, where it drives oxygenation reactions to boost crude oil viscosity and concentration, prevents pipeline deposits, and enhances storage stability against oxidation. Cobalt(II) acetate tetrahydrate is a trusted cobalt source used to make cobalt-containing cathode materials for lithium and sodium-ion batteries. For instance, it helps synthesize layered lithium-rich manganese-based oxide (LRMO) cathodes alongside other metal precursors. It is also used to create NiCo₂Se₄/carbon nanotube composites through one-step solid-phase synthesis for hybrid supercapacitors and sodium-ion batteries, enabling efficient energy storage materials. Furthermore, Cobalt(II) acetate tetrahydrate acts as a drier catalyst in alkyd paints and varnishes, speeding up drying by oxidizing unsaturated fatty acids to improve film hardness and gloss. It also serves as a mordant in textile dyeing for better color fastness and as a precursor for cobalt aluminate pigments, creating stable blue shades in ceramics and fabrics.[5]Our ≥99.9% trace metals basis Cobalt(II) acetate tetrahydrate ensures optimal performance in catalysts, battery cathodes, paints, and dyes by minimizing impurities for superior yields, consistency, and material quality
