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...
NIR‐Triggered Antibacterial Therapy
In article number 2102315, Xiaohua Yu, Zhaoming Ye, and co‐workers successfully transform the utility of iodine from external use to orthopedic implants leveraging the superior loading capacity of metal–organic frameworks. Such an immobilization approach skillfully bypasses the insolubility and vulnerability associated with iodine when turned for internal use. Under...
Iodine has been known as an effective disinfectant with broad‐spectrum antimicrobial potency yet without drug resistance risk when used in clinic. However, the exploration of iodine for antibacterial therapy in orthopedics remains sparse due to its volatile nature and poor solubility. Herein, leveraging the superior absorption capability of metal–organic frameworks (MOFs) and their inherent photocatalytic...
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...
Precisely engineering the decoration of metal nanoparticles on the special surface of semiconductor represents a promising strategy to design efficient metal–semiconductor heterostructured photocatalysts. This study demonstrates a versatile soft‐template method to fabricate a novel nonsymmetrical heterostructured Ag/AgI nanoplate, in which only one side surface of the nanoplate is covered with uniform...
Nanocasting, using ordered mesoporous silica or carbon as a hard template, has enormous potential for preparing novel mesoporous materials with new structures and compositions. Although a variety of mesoporous materials have been synthesized in recent years, the growth mechanism of nanostructures in a confined space, such as mesoporous channels, is not well understood, which hampers the controlled...
