Abstract

We demonstrate that the highly photoredox active metal-organic framework (MOF) MIL-125-NHCyp exhibits crystalline and porosity stability in humid environments for more than 30 days as well as increased hydrophobicity compared to the unfunctionalized framework. This improved stability, in synergy with its high photocatalytic activity, makes this MOF a very promising candidate for large-scale applications in CO2 photoreduction.
