Summary: A novel strategy for the synthesis of bimetal SNCs stabilized within hierarchical porous carbons (HPC) was reported in this study. The obtained Cu-Pd@HPC composite exhibited superior catalytic activity and recycling durability in the selective transformation of furfural to maleic acid. DFT calculations revealed the mechanism behind the enhanced catalytic activity by introducing Pd into the system.

Summary: MOFs and COFs are two frontier crystalline porous framework materials, each with its own advantages and shortcomings for specific applications. However, combining the complementary properties of the two materials allows for the creation of new classes of hybrid porous crystalline materials with superior properties. The rapid evolution of MOF/COF hybrids since their first report in 2016 has led to diverse applications in various fields.

Summary: The past few decades have seen a rapid development in the research of metal-organic frameworks (MOFs). Although most initially reported MOFs were limited to microporous structures, their intrinsic pore size has been enlarged by extending the building units or organic ligands. However, the synthesis of larger ligands is challenging and most MOFs are not stable enough. The soft-template strategy offers a promising approach to produce hierarchically porous MOFs (HPMOFs), but early attempts failed due to incompatibility. Therefore, developing a rational soft-template strategy for precise control of HPMOFs' morphology and porosity is of great significance.

Summary: Porous nitrogen-doped carbon nanocages (PNCCs) were synthesized by one-step pyrolysis of energy-efficient Zn-based MOF (MET-6), and demonstrated high efficiency as PMS activators for decomposing organic micropollutants. PNCCs-900 exhibited remarkable catalytic activity for RhB degradation due to its high specific surface area (894.9 m(2) g(-1)), nitrogen doping level (13.1%), and optimal nitrogen configuration ratio. This study opens up a new avenue for the development of efficient PMS activators for water remediation.

Summary: Nanogenerators (NGs) are a potential technology for self-powered systems and portable electronics in the Internet of Things generation. They convert mechanical motion into electrical signals and have evolved since their discovery in 2006 and 2012. Crystalline porous materials (CPMs) such as metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have been widely studied as efficient material options for NGs due to their special properties.
