Synthesis and characterization of bimetallic Cu-Al-BTC MOFs as an efficient catalyst for selective catalysis reduction of NO with CO.

Bimetallic Cu-Al-BTC MOFs with various Cu/Al ratios were successfully synthesized via a hydrothermal method and applied for CO-SCR. It is found that the catalytic efficiency increased significantly with Cu:Al ratio from 1:1 to 6:1. 6Cu1Al-BTC catalyst exhibits the highest catalytic activity, which achieves nearly 100% NO conversion in the temperature range from 325 °C to 400 °C. All bimetallic Cu-Al-BTC catalysts showed higher catalytic activity than pure Cu-BTC and Al-BTC materials. The feasibility of bimetallic Cu-Al-BTC MOFs as a novel deNO_x catalyst was evaluated in this work. [ABSTRACT FROM AUTHOR]
