โฆ Synopsis
The effects of alkali (sodium hydroxide) treatment on the physico-chemical properties and catalytic activity for H 2 O 2 decomposition and CO oxidation of Indian Ocean manganese nodules have been studied. The surface area, surface oxygen, surface hydroxyl groups, etc. increase with alkali treatment up to 0.05 M and there after show a decreasing trend. The high catalytic activity of 0.05 M NaOH treated samples are correlated with the surface properties.
