A wide-spectrum-driven photoanode was prepared by coating a 2-5 nm nitrogen-doped carbon(N-C)layer onto TiO2 nanorod array in a mixed solution of glucose and ethanediamine under hydrothermal condition.1 The nitrogen-doped carbon layer extended the photoresponse of TiO2 nanorod array from UV to NIR region.The IPCE of the pristine TiO2 nanorod array was about 45%in the UV region,but dropped rapidly to 0 after wavelength of 420 nm.2 By contract,the IPCE of N-C-TiO2 nanorod array exhibited 10%improvement than that of the TiO2 nanorod array,and maintained at about 0.5-2.0%in the Vis region(420-800 nm),and about 0.1-0.5%in the NIR region(>800 nm)at 1.0 V vs.RHE.Besides,the photocurrent of N-C-TiO2 nanorod array was superior to that of pristine TiO2 nanorod arrays with an on-set potential shifted negatively by 0.1 V.The N-C layer was confirmed to behave like a p-type semiconductor and formed a p-n junction with the n-type TiO2 nanorod.The N-C layer facilitated charge transportation and contributed to the generation of photocurrent under Vis and NIR illumination.
