英文摘要	we report on the design and synthesis of a novel au/tio2/au heterostructure and its implementation as a photoanode for photoelectrochemical (pec) application. the au/tio2/au heterostructure was produced by assembling au nanoparticles and tio2 nanorods (nrs) onto fto substrate, followed by electrodepositing au nanoparticles on the tio(2)nrs. field emission scanning electron microscopy (fesem), x-ray photoelectron spectroscopy (xps), x-ray diffraction (xrd), and electrochemical methods were adopted to characterize the prepared photoanodes. compared to the system involving au nanoparticles directly linked to tio2, this au/tio2/au heterostructure exhibits significant improved photoresponse as a photoanode, as demonstrated good performance in pecs. this study illustrates the importance of pre-deposited au underlayers in influencing pec properties of hybrid assembled nanostructures. as the au/tio(2)nrs/au photoanodes are easily fabricated and highly stable, au/tio(2)nrs/au can serve as a good substitution for tio2 in a variety of solar energy driven applications including pec water splitting, photocatalysis, and solar cells. copyright (c) 2013, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
