Figures

Image of FIG. 1.
FIG. 1.

(Color online) Simplified scheme of atomic layer deposition by using Al2O3 ALD as the example. TMA: Trimethyl aluminum. Reprinted with permission from Ref. 132 (copyright 2007 American Chemical Society).

Image of FIG. 2.
FIG. 2.

(Color online) Principle diagram of water splitting process by using (a) single semiconductor/liquid junction; (b) photovoltaic cell assisted semiconductor/liquid junction; (c) dye sensitized semiconductor/liquid junction. CB: conduction band; VB: valence band; Ef: Fermi level; HER: hydrogen evolution reaction; OER: oxygen evolution reaction. For effective water splitting, electrons and holes need to have enough energy for HER and OER reaction. Electrodes need to be stable under dark and light condition. Detail mechanisms of different types of PEC cells have been discussed in other reviews Refs. 4, 11, and 12.

(Color online) (a) SEM image of the Cu2O electrodes after coated with 5 × (4 nm ZnO/0.17 nm Al2O3)/11 nm TiO2 followed by electrodeposition of Pt nanoparticles. Reprinted with permission from Ref. 35 (copyright 2011 Nature Publication Group). (b) TEM image of the nanocomposite anode of Si/SiO2/ALD TiO2/Ir. Reprinted with permission from Ref. 37 (copyright 2011 Nature Publication Group). (c) TEM image of the core-shell TiSi2/TiO2 structure. Reprinted with permission from Ref. 39 (copyright 2009 American Chemical Society). (d) UV-vis spectra of ALD TiO2 and ALD W doped TiO2 (W0.3Ti0.7O2). Reprinted with permission from Ref. 39 (copyright 2009 American Chemical Society).

Image of FIG. 4.
FIG. 4.

(Color online) (a) Simplified diagram for Dye sensitized solar cell. Dye molecules adsorbed onto nanostructured semiconductor surface. After excited by photon, dye molecules will inject an electron into conduction band of semiconductors. The oxidized dye molecules will be reduced by the redox shuttle. The oxidized redox species will be reduced on the counter electrode by the electrons from the photoanode through external circuit. (b) Diagram of electron and hole transport inside of the DSSC cell, “Red” and “Ox” are the reduction and oxidation status of redox couple correspondingly. LUMO: lowest unoccupied molecular orbital; HOMO: highest occupied molecular orbital.

(b) Interfacial energetics of ZnO nanowire coated with TiO2, where electrons flow from TiO2 to ZnO. Reprinted with permission from Ref. 72 (copyright 2006 American Chemical Society). (c) J-V curves for DSSCs based on naked SnO2 (solid line) and on SnO2 coated with one cycle of Al2O3 (dashed line). Reprinted with permission from Ref. 74 (copyright 2010 American Chemical Society). (d) Aerogel scaffold coated with 8.4 nm ZnO ALD process. Reprinted with permission from Ref. 75 (copyright 2008 Wiley-VCH).
