Figure 1: Mesocrystal Photoanode Formation and Photochemical Water Splitting Characteristics

Caption

a. Electron microscope image of a hematite mesocrystal (assembled from tiny nano-particles of approx. 5nm). b. Gas production from the anode. c. Graph to show the current density and applied voltage. The anode is the photocatalyst anode, and a platinum electrode was used for the cathode. The potential is based on the RHE (Reversible Hydrogen Electrode). The oxidation potential is 1.23V. The solar water splitting capacity was greatly enhanced by making the nano-particles in the mesocrystal structures smaller.
