A novel method for assessing the activity of a powdered water oxidation catalyst (WOC) is described, utilising an easily-prepared wireless rotating disc electrode of the WOC, thereby allowing its activity to be probed, via the observed kinetics of water oxidation by Ce(iv) ions, and so provide invaluable electrochemical information.

The rate constant for the irreversible dehydration of a number of aromatic aldehyde hydrates has been measured. The hydrates were generated by constant potential electrolysis of the respective aromatic acid at a rotating disc electrode. The aldehydes are then further reduced to the alcohol. The rate constant can be calculated from the ratio of the concentration of intermediate aldehyde to the total concentration of products.The theory was further extended to include the reverse hydration of the aldehyde to the hydrate and applied in the case of m-chlorobenzaldehyde. A value for the equilibrium constant of K = 1.30 ± 0.25 was obtained for this reaction.
