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.

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。
