Scientists in China have designed a low-cost copper-amine complex and used it as a template for the one-pot synthesis of a zeolite that exhibits excellent catalytic performance.
Feng-Shou Xiao from Zhejiang University and co-workers from Jilin and Beijing Normal Universities, worked together on rationally designing the copper zeolite (Cu-ZJM-1) with changeable Si/Al ratios. The resulting Cu-ZJM-1 has much higher copper content and a better dispersion of copper cations compared to other zeolites reported in the literature. It exhibits excellent properties when it comes to the selective catalytic reduction of the environmentally harmful gas nitrogen oxide (NOx), by ammonia.
