The formation process of zeolitic imidazolate framework (ZIF)-67 derived Co/N-doped carbon nanocomposites is dynamically investigated by in-situ transmission electron microscopy (TEM) assisted with ex-situ characterizations. Several key findings were observed: (1) graphitization of carbon; (2) volatilization of Co nanocrystals; (3) generation process of carbon nanotubes (CNTs) catalyzed by Co. The nanocomposites show high-efficient microwave absorption performance that can be tuned by pyrolysis temperature, heating rate, and mass fraction. These findings are helpful to understand the formation of metal-organic frameworks (MOFs) derived carbon-based composites and expand their practical applications.

Finally, the rate-determining step of CO2 photoreduction and the charge change on Cu form an inverse volcano curve.

The complex doping effect and temperature dependence of Mn ion spin state have an important effect on the dielectric behavior of La1−xSrxMn1−yFeyO3 perovskite materials at high temperature. The content of Mn3+ in the high-spin and low-spin states is dynamically changing with the increase of temperature. The spin state of Mn ions and the crystal structure of perovskite affect the high-temperature dielectric behavior of La1−xSrxMn1−yFeyO3 by acting on the double-exchange interaction, making it possible to maintain efficient absorption of electromagnetic waves in high temperature. In addition, the cellular array structure obtained by computer simulation technology (CST) simulation software can introduce magnetic loss and further improve the service temperature of materials.

Three-stage alloying of [Ag44(p-MBA)30]4− cluster with [Au2(p-NTP)2Cl]−
Baoyu Huang, Xiaomei Zhao, and Yong Pei*
Xiangtan University, China
The density functional theory (DFT) calculation results demonstrated that the metal exchange proceeded via different mechanisms at different reaction stages. In reaction stages I and II, the metal exchange proceeded via formation of a dianionic [Ag44(p-MBA)30]4−-[Au2(p-NTP)2Cl]− intermediate and then broke and recombined with the ligand-shell. In stage III, the diffusion of Au(I) to icosahedral Ag12-core (stage III) proceeded via a motif catalyzed heterometal atom diffusion mechanism.
