Abstract

Galvanic deposition of Au onto a thin-sheet sinter-locked 8 μm Ni-fiber delivers a high-performance Au/Ni-fiber catalyst for alcohol oxidation, due to the unique combination of excellent heat conductivity, remarkable low-temperature activity, and good stability/regenerability. The special NiO@Au ensembles formed during the reaction contribute to promoting the low-temperature activity.

摘要

通过在薄片状烧结锁定的 8μm 镍纤维上电沉积 Au，得到了一种高性能的 Au/Ni 纤维催化剂，用于醇氧化，这是由于其优异的导热性、显著的低温活性以及良好的稳定性/可再生性的独特结合。反应过程中形成的特殊 NiO@Au 组合有助于提高低温活性。
