In this study, an atomically controlled thin TiO2 layer was coated on Au/C by atomic layer deposition (ALD). The resulting TiO2 coated Au/C (ALD(TiO2)-Au/C) was used as a catalyst for electrocatalytic glycerol oxidation in alkaline media. Interactions between Au and TiO2 in the ALD(TiO2)-Au/C catalyst improved the catalytic activity and stability for glycerol oxidation. Additionally, the reaction pathway for glycerol oxidation changes due to the Au-TiO2 interfaces formed by ALD. This performance enhancement of electrocatalytic glycerol oxidation on ALD(TiO2)-Au/C is attributed to the role of TiO2 in facilitating oxidation of the Au surface.

Au-TiO 2界面部位在增强电催化甘油氧化性能中的作用
在这项研究中,通过原子层沉积(ALD)在Au / C上涂覆了原子控制的TiO 2薄层。将所得的涂覆有TiO 2的Au / C(ALD(TiO 2)-Au / C)用作在碱性介质中电催化甘油氧化的催化剂。ALD(TiO 2)-Au / C催化剂中Au与TiO 2的相互作用提高了甘油氧化的催化活性和稳定性。另外,由于ALD形成的Au-TiO 2界面,甘油氧化的反应途径改变。ALD(TiO 2)-Au / C上电催化甘油氧化的这种性能增强归因于TiO 2的作用 促进Au表面的氧化。
