Radio frequency alternating electromagnetic field enhanced tetraruthenium polyoxometalate electrocatalytic water oxidation†
Abstract
Application of radio frequency (RF) electromagnetic waves enhances the electrocatalytic water oxidation by protonated tetraruthenium polyoxometalate ([Ru4(μ-O)4(μ-OH)2(H2O)4(γ-SiW10O36)2]10−). In particular, an enhancement factor of 3.6 is achieved when the level of proton substitution of protonated tetraruthenium polyoxometalate is changed from zero to 9 under application of RF at 200 MHz.
