Abstract

To compare the catalytic oxidation activities of reduced graphene oxide (rGO) and rGO samples doped with five different transition metals (TM-rGO), we determine their effects on the oxidation of L-cysteine (Cys) in aqueous solution by performing electrochemistry (EC) measurements and on the photocatalytic oxidation of Cys by using high-resolution photoemission spectroscopy (HRPES) under UV illumination. Our results show that Cr-, Fe-, and Co-doped rGO with 3+ charge states (stable oxide forms: Cr, Fe, and Co) exhibit enhanced catalytic activities that are due to the charge states of the doped metal ions as we compare them with Cr-, Fe-, and Co-doped rGO with 2+ charge states. The SEM images and the corresponding EC measurements for (a) Cr3+, (b) Fe3+, and

摘要

为了比较还原氧化石墨烯（rGO）和掺杂五种不同过渡金属的rGO样品（TM-rGO）的催化氧化活性，我们通过进行电化学（EC）测量来确定它们对水溶液中L-半胱氨酸（Cys）氧化的影响，并在紫外光照射下使用高分辨率光电子能谱（HRPES）来研究它们对Cys光催化氧化的影响。我们的结果表明，具有3+电荷态（稳定氧化物形式：Cr、Fe和Co）的Cr-、Fe-和Co掺杂rGO表现出增强的催化活性，这是由于与具有2+电荷态的Cr-、Fe-和Co掺杂rGO相比，掺杂金属离子的电荷态所致。（a）Cr3+、（b）Fe3+的扫描电子显微镜图像及相应的EC测量结果，以及……
