The V_B-containing defective h-BN sheet is proved to be a feasible support for atomic transition-metal anchoring. In particular, we found the Cu@h-BN and Ni@h-BN are highly active and selective catalysts for NO electro-reduction to generate NH₃.

A B ₃₆ nanoflake is capable of capturing atomic Au and such a single-atom catalyst is highly active and selective to promote the electroreduction of CO ₂ to formic acid.

The meso -substituents of Fe porphyrins play critical roles in regulating the electrocatalytic properties for CO ₂ reduction, showing significantly improved activity with increased electron-donating features of meso -substituents.
