Abstract
Shaped particles, comprising a calcium aluminate cement and at least one oxide of a Group VIII metal M selected from nickel and cobalt, said particles containing 10 to 70% by weight of said Group VIII metal oxide (expressed as the divalent oxide, MO) and having a porosity in the range 25 to 50%, in which at least 30% of the pore volume is in the form of pores of size in the range 15 to 35 nm and less than 40% of the pore volume is in the form of pores of diameter greater than 35 nm. These particles are used to catalytically decompose oxidizing agents including hypohalites.
