     in this work, we studied several manufacture characteristics of various metal catalysts of ni, co, cu, and fe for the catalytic decomposition of a sodium hypochlorite solution. the metal oxide, metal hydroxide, and metal oxide–hydroxide forms were prepared and compared. ultimately, a bead-type catalyst impregnated with a metal oxide–hydroxide mixture was manufactured and evaluated. the metal ions were oxidized and precipitated in the form of metal oxide–hydroxide or metal oxide in a hypochlorite solution, and the precipitates could decompose the hypochlorite in solution. the ni oxide–hydroxide catalyst showed the best hypochlorite decomposition performance and was the most stable among the other metal catalysts as well as the ni hydroxide and ni oxide catalysts. when the ni oxide–hydroxide catalyst was manufactured in a hypochlorite solution, an optimal mixing volume ratio of hypochlorite solution to the metal ion solution was achieved. a column packed with ni oxide–hydroxide beads was confirmed to continuously and effectively decompose hypochlorite in seawater.
