a HCHO conversion to CO2. b Reaction activation energy, Ea. Individual ZSM-5 and Ag/SBA-15 components are listed for comparison. Effect of (c) mass ratio of ZSM-5 zeolite to Ag/SBA-15 component and d intimacy of the two components in composites. Reaction conditions: 60 °C, 100 ppm HCHO, 20% O2–Ar, and gas hourly space velocity (GHSV) with respect to ZSM-5−Ag/SBA-15 bifunctional catalysts is 36000 mL g−1 h−1.
