A fish-in-hole strategy for preparing a Pd nanoparticle catalyst was reported, which is achieved by controllable positioning of Pd nanoparticles individually at the traps of zeolite crystals. This Pd catalyst was sinter-resistant under high-temperature calcination and CO oxidation, outperforming the conventional supported catalyst consisting of supported Pd nanoparticles synthesized via the traditional deposition method.
报道了一种制备钯纳米颗粒催化剂的“孔内鱼”策略，该策略通过将钯纳米颗粒单独可控地定位在沸石晶体的陷阱处来实现。这种钯催化剂在高温煅烧和一氧化碳氧化条件下具有抗烧结性能，优于通过传统沉积方法合成的负载型钯纳米颗粒组成的传统负载型催化剂。
