Seaweed-like phosphates/MOF heterostructures as a synergistic electrocatalyst for alcohol oxidation.

A series of seaweed-like heterogeneous Co 3 (PO 4 ) 2 /Ni 3 (PO 4 ) 2 /MOF-74- x electrocatalysts were synthesized via a hydrothermal method. The optimal composite exhibits excellent catalytic performance toward methanol/ethanol oxidation reactions (MOR/EOR) with peak current densities reaching 27.5 and 32.6 mA cm -2 , respectively. This work heralds the advent of more efficient heterogeneous electrocatalysts for DAFCs and other energy conversion systems.
