The development of single-atom catalysts (SACs) for electrocatalytic nitrogen reduction reaction (NRR) remains a great challenge. Using density functional theory calculations, we design a new family of two-dimensional metal-organic frameworks...

Utilizing first-principles density functional theory calculations, we identify that weak adhesion of metal clusters (for example Cu and Au) on pristine MOF-5, IRMOF-3, IRMOF-3-OH and IRMOF-3-SH, which reveals that metal clusters may be unable to stably exist in the pore of MOFs. Furthermore, upon removing the hydrogen of NH2, SH and OH functional groups, the adsorption energy between metal cluster and functionalized MOFs improve, which ascribes to chemical adsorption. Meanwhile, these metal clusters become cationic as a result of the formation of metal-O, S or N adhesion bonds. Hence, our study may provide a candidate approach to deposit metal clusters into the pore of MOFs.

Contrary to common believe, for eight adsorption cases, neither D3 or TS are an improvement compared to D2 nor van der Waals functionals or dDsC. Only the many body approaches are slightly better than D2(Ne) which uses Ne parameters for Mg2+ ions.
