A two-dimensional metal-organic framework (2D MOF) includes a first transition metal Mand a second transition metal M. The first transition metal and the second transition metal are different and are coupled by a linker group L to yield a two-dimensional metal-organic framework alloy having a formula MML, where 0&#x3c;x&#x3c;1. Each transition metal is dispersed uniformly throughout the 2D MOF. The 2D MOF is synthesized by combining a first transition metal precursor, a second transition metal precursor, and a linker; agitating the solution; and heating the solution to yield a crystalline two-dimensional metal-organic framework alloy.

Two-dimensional metal-organic framework alloy photocatalysts

Some embodiments include a method of preparing a phototuned metal-organic framework by forming a first solution by dissolving ZrOCl.8HO in dimethylformamide (DMF) and formic acid, mixing and dissolving 1,4-phenylenediacrylic acid in a second solution of dimethylformamide (DMF) and trimethylamine, and at least partially mixing the first and second solutions to form a mixture. The method further includes sealing the mixture in an autoclave and heating the mixture to above ambient temperature for a specified period of time to prepare ZrPDA metal-organic framework, and extracting the ZrPDA metal-organic framework and at least partially reacting to a specified degree at least some of ZrPDA metal-organic framework through [2+2] cycloaddition reactions. The specified degree can be tunable based at least in part on at least one of the intensity of UV radiation, the exposure time, and the UV wavelength.
