Water Promoted Efficient Low-Temperature CO Elimination over Meso-Structured Pd/NiO Catalyst Under Ambient Condition

The mesostructured Pd/NiO catalyst was fabricated by in-situ reduction method. For 5.3 wt% Pd loaded catalyst, the 100% conversion temperature was about -20 ^oC when 1.2 vol% H₂O was introduced into the feed gas. The catalytic activity had not any decrease even after 100 hours reaction.
