<p><i>Operando</i> spectroelectrochemical analysis is used to determine the water oxidation reaction kinetics for hematite photoanodes prepared using four different synthetic procedures. Whilst these photoanodes exhibit very different current / voltage performance, their underlying water oxidation kinetics are found to be almost invariant. Lower photoanode performance was found to correlate with the observation of optical signals indicative of charge accumulation in mid-gap oxygen vacancy states, indicating these states do not contribute directly to water oxidation.</p>

Hybrid electrocatalyst of ultrafine Pt particles anchored on a Ni3[Fe(CN)6]2 nanocube with low Pt loading of 4.0% is designed for HERs, and superior catalytic activity is obtained in both acidic and alkaline media because the Ni species remarkably facilitates the reaction kinetics of water dissociation and thus improves HER activity.

Dual Functions

Advances of application of ionic liquids as solvents and catalysts in the catalytic oxidation reaction are summarized in this paper. Ionic liquids, as solvent, can provide an environment which is different from the traditional organic solvents for the chemical reactions, and make the catalytic activity and stability better, conversion and selectivity higher; Ionic liquids, as catalyst, not only play the function of promoting reaction, but also play a solvent/catalyst dual functions more directly. Currently ionic liquids in catalytic oxidation reaction are mostly used as solvent, Especially used widely in organic synthesis. The designability of ionic liquids provides a broad space for ionic liquids as catalyst.
