Sodium borohydride hydrolysis is one of the promising methods for the supply of hydrogen on-board in fuel cell vehicle. A suitable catalyst is required to control the hydrogen release from stable alkaline sodium borohydride solution. The present paper reports the effect of Co (II) doped zeolite-X and K-chabazite catalysts in sodium borohydride hydrolysis reaction. Kinetics of the hydrolysis reaction was observed to get enhanced by the use of these catalysts. Activation energies for Co (II) doped K-chabazite and zeolite-X are found to be 30.7 and 48 kJ mol-1, respectively.

<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>
