“…[16][17][18][19][20] However, due to their poor stability in water, only a handful of water-tolerant MOFs, such as ZIF-8, MIL-125(Ti), and MIL-53(Fe), can be employed as photocatalysts to reduce TC in water media. [21][22][23] However, these MOFs usually exhibit a photoresponse in the ultraviolet light region, which limits their reduction performance. In order to extend the adsorption edge into the visible-light region, a feasible strategy is to decorate linkers with functional groups with a strong electrondonating ability, such as -SH, -NH 2 , pyrene, porphyrin, and Ru(bpy) 3 2+ (bpy = 2,2′-bipyridine).…”
