Hollow Mo-doped CoP nanoarrays for efficient overall water splitting

Hollow Mo-CoP nanoarrays on carbon cloth are derived from a metal-organic framework precursor, and directly utilized as a highly active and durable electrocatalyst for hydrogen evolution. The Mo-CoP arrays can also be in situ transformed into Mo-CoOOH with enhanced OER properties. An electrolyzer using Mo-CoP and Mo-CoOOH can be powered by a single AA battery (~1.5 V), offering great promise for practical applications.385
