FeFx and Fe2ZrO5 Co-modified hematite for highly efficient solar water splitting
文献摘要：
Hematite is an excellent catalyst for photoelectrochemical(PEC)water splitting but its performance has been highly limited by poor conductivity and high charge recombination.Here by a Zr-based treatment to create bulk Fe2ZrO5 in hematite and a F-based treatment to form an ultrathin surface FeFx layer,the charge transfer can be highly improved and the charge recombination can be significantly suppressed.As a result,the FeFx/Zr-Fe2O3 photoanode presents an enhanced PEC performance with a photocurrent density of 2.43 mA/cm2 at 1.23 V vs.RHE,which is around 3 times higher than that of the pristine Fe2O3.The FeFx/Zr-Fe2O3 photoanode also shows a low onset potential of 0.77 V vs.RHE(100 mV lower than the pristine hematite).The performance is much higher than that of the sample treated by Zr or F alone,suggesting the synergistic effect between bulk Fe2ZrO5 and surface FeFx.By coupling with the FeNiOOH co-catalyst,the final photoanode can achieve a high photocurrent density of 2.81 mA/cm2 at 1.23 V vs.RHE.The novel design of Zr and F co-modified hematite can be used as a promising way to pre-pare efficient catalysts for solar water splitting.
