水の光電気化学的酸化分解に活性な BiVO4薄膜光電極への Zr 添加効果 Impacts of Zr-doping in BiVO4 thin-film electrode on its photoelectrochemical property for water oxidation 川口, 誉人 カワグチ, タカト KAWAGUCHI, Takato 00379314 原田, 隆史 ハラダ, タカシ HARADA, Takashi 40333447 中西, 周次 ナカニシ, シュウジ NAKANISHI, Syuji Islam, MD.

The BiVO4 electrodes with different Zr contents were prepared via a spin-coating process. Structural analyses using XRD and Raman spectroscopy indicated that all the samples consisted of mixtures of monoclinic scheelite (ms-BiVO4) and tetragonal scheelite (ts-BiVO4) structures. The highest PEC property for water oxidation was achieved when the sample doped with a relatively small amount of Zr (i.e., 0.5% of Zr-doped BiVO4); further doping caused a reduction of PEC property, probably due to the enhancement of carrier recombination induced by such excess Zr components. 甲南大学 2019-01-22 jpn departmental bulletin paper VoR https://doi.org/10.14990/00003209 https://konan-u.repo.nii.ac.jp/records/3235 10.14990/00003209 AA11561231 24346446 甲南大学紀要. 理工学編 Memoirs of Konan University.
