Ru Catalyst

The nitrogen reduction reaction (NRR) pathways involving various N–N dissociation steps are found to be comparable to the conventional associative mechanism. The competitive hydrogen adsorption and evolution is revealed to negatively affect the NRR for two reasons, an increase in NRR overpotentials as a function of partial H-coverages as well as a decreased number of active sites.

Hydrolysis Of

UiO-67-bpydc-Zn with isolated multi-catalytic active sites was fabricated as a catalyst for the hydrolysis of bis(p-nitrophenyl) phosphate as a DNA model. The enhanced activity may likely be attributed to the cooperation effects between the Lewis acid from the zirconium center at the node and the zinc hydroxide Lewis base in the linkers.
