The incorporation of a transition metal into a noble metal for the formation of nanoalloys paves a potential way to modulate the electronic structures and spatial arrangement modes, thereby manipulating the target catalysis under the desired reaction pathways. Herein, a top‐down synthetic route to fabricate IrCo nanoalloys with delicately designed compositions and morphologies at an extremely low...
Optical microsphere resonators working in the near‐ and mid‐infrared regions are highly required for a variety of applications, such as optical sensors, filters, modulators, and microlasers. Here, a simple and low‐cost approach is reported for batch fabrication of high‐quality chalcogenide glass (ChG) microsphere resonators by melting high‐purity ChG powders in an oil environment. Q factors as high...
Nanometals have been proven to be efficient thermocatalysts in the last decades. Their enhanced catalytic activity and tunable functionalities make them intriguing candidates for a wide range of catalytic applications, such as gaseous reactions and compound synthesis/decomposition. On the other hand, the enhanced specific surface energy and reactivity of nanometals can lead to configuration transformation...
Inspired by bio‐enzymes, multistep cascade reactions are highly attractive in catalysis. Despite extensive research in recent years, it remains a challenge to promote the stability and activity of catalysts. Here, well‐defined core–shell structured Ag–Au nanocage@CeO2 (Ag–Au NC@CeO2) are designed by a simple and facile self‐assembly method. The results indicate that the Ag–Au NC@CeO2 has glucose oxidase‐like...
