The invention relates to a photoanode, in particular to a preparing method and an application of a TiO2, RGO and C3N4 compound electrode. First, a TiO2 nanorod array is prepared on an FTO substrate by a universal low-temperature liquid phase process through hydrothermal reaction. Then, one layer of oxidized grapheme and carbon nitride mixture is uniformly smeared on the TiO2 nanorod array in a spinning manner by adopting a spinning coating process. Finally, the TiO2 nanorod array is forged under nitrogen protection to form the TiO2, RGO and C3N4 compound electrode. A thin film for reducing the oxidized grapheme (RGO) and the carbon nitride (C3N4) is loaded on the TiO2 nanorod array through the simple and convenient method to expand the response to solar light, so that the sunlight utilizing rate of the electrode is increased. 本发明涉及光电阳极，特指种TiO/RGO/CN复合电极的制备方法及用途。本发明首先采用通用的低温液相法经水热反应在FTO基片上制备出TiO纳米棒阵列，继而利用旋凃法在其之上均匀地旋涂层氧化石墨烯与氮化碳的混合物，最后将其在氮气保护下煅烧形成TiO/RGO/CN复合电极。通过简单方便的方法在二氧化钛(TiO)纳米棒阵列负载还原氧化石墨烯(RGO)和氮化碳(CN)的薄膜来扩
