Highly Efficient and Stable Au/FeOx-HAP Catalyst for CO Oxidation

Catalysis by gold has emerged since the pioneering discovery that supported gold catalysts could be active for CO oxidation even below room temperature. But the sintering of nano-gold at high temperatures (e.g. ≥ 400 oC) constrained their practical application. Therefore, it is challenging to explore gold catalyst with highly sinter-resistant performance meanwhile keep their high activity. Here, we designed a novel hydroxyapatite (HAP)-based catalyst Au/FeOx-HAP which was highly sinter-resistant and highly active and durable for CO oxidation.Catalysis by gold has emerged since the pioneering discovery that supported gold catalysts could be active for CO oxidation even below room temperature.
