The site pair matching of a tandem Au/CuO–CuO nanocatalyst for promoting the selective electrolysis of CO2 to C2 products

C2 product FE of 52.8% was achieved in eCO2RR at −1.0 V vs. RHE using a nanoporous hollow Au/CuO–CuO tandem catalyst due to the matching of optimal working potentials and charge-transfer resistances of the CO-production sites and CO-reduction sites.

The synergic effects at the molecular level in CoS2 for selective hydrogenation of nitroarenes

The face to face located terdentate and tetrahedral coordinated Co atoms in CoS2/PC form a “synergic active site pair”, showing superior activity and selectivity in the hydrogenation of nitroarenes.

Insights into the synergistic role of metal–lattice oxygen site pairs in four-centered C–H bond activation of methane: the case of CuO

Of the three mechanisms for activation of methane on copper and copper oxide surfaces, the under-coordinated Cu–O site pair mediated mechanism on CuO surfaces has the lowest activation energy barriers.
