Carbon dioxide utilization in catalysis

A Pd/α-Al2O3 nanocatalyst with ultra-low Pd loading exhibits high activity and stability for CO oxidative coupling to dimethyl oxalate, which was prepared by a Cu2+-assisted in situ reduction method at room temperature. The small size and high dispersion of Pd nanoparticles facilitated by Cu2+ ions are responsible for the excellent catalytic activity.
