Carbonaceous chars capable of catalyti- cally decomposing aqueous hydrogen peroxide at higher rates at given char densities than other known catalytic chars are provided for. This improvement is provided by an increase in the catalytic activity at a given char density of the said catalytically-active carbonaceous char. The catalytically-active carbonaceous chars ase useful for, but not limited to, the catalytic conversion of H2S, SO x, NO x, peroxides, and/or chloramines in liquid and/or gaseous media. The catalytic activ- ity of the char can be measured by adding the char to an apparatus (10) comprising a Dewar container (11) positioned on a magnetic stirrer (12) including a stir bar (13), a cap (14), a fun- nel (15), a vent (16), an opening (17), a thermo- couple (18), an ice point compensator (21) and a strip chart recorder (22).
