Figure 1. CO-SCR performance of Ir-Mo@Z5 and Ir-Mo/Z5 catalysts: (A) NO conversion, (B) NO_x conversion, (C) CO conversion, and (D) N₂ selectivity. Reaction conditions: [NO] = 400 ppm, [CO] = 8,000 ppm, [O₂] = 5%, [SO₂] = 200 ppm (when used), GHSV = 16,000 h^-1. SCR: Selective catalytic reduction; GHSV: gas hourly space velocity.
