Abstract
Catalytic activity of gold nanoparticle (NP)-loaded metal oxide semiconductors (Au/MOs) for H(2)O(2) decomposition and chemoselective oxidation of cinnamyl alcohol to cinnamaldehyde strongly depends on both the kind of the MO-supports and the Au particle size, and Au/SrTiO(3) exhibits an extraordinary high level of activity for the H(2)O(2) decomposition exceeding that of Pt/TiO(2).
摘要
负载金纳米颗粒（Au/NPs）的金属氧化物半导体（Au/MOs）对 H(2)O(2)分解和肉桂醇选择性氧化为肉桂醛的催化活性强烈依赖于 MO 载体的种类和 Au 颗粒尺寸，而 Au/SrTiO(3) 对 H(2)O(2)分解的活性极高，超过了 Pt/TiO(2)。
