Two-dimensional metal-organic framework alloy photocatalysts

Abstract

A two-dimensional metal-organic framework (2D MOF) includes a first transition metal M 1 and a second transition metal M 2 . 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 M 1 x M 2 1-x L, where 0<x<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.
