The sluggish kinetics of the hydrogen evolution reaction (HER) result in a high overpotential in alkaline solutions. A high-curvature metal oxide heterostructure can effectively boost the electrocatalytic HER by leveraging the tip-enhanced local electric field effect. Herein, NiP/NiMoO nanocones were synthesised on a nickel foam (NF) substrate by etching a metal-organic framework template.

This review examines the recent advancements and unique properties of polymer-inorganic hybrid materials formed through coordination bonding (Class II hybrids), which enable enhanced functionality and stability across various applications. Here, we categorize these materials based on properties gained through complexation, focusing on electrical conductivity, thermal stability, photophysical characteristics, catalytic activity, and nanoscale self-assembly. Two major synthetic approaches to making these hybrids include homogeneous and heterogeneous methods, each with distinct tradeoffs: Homogeneous synthesis is straightforward but requires favorable mixing between inorganic and polymer species, which are predominantly water-soluble complexes.

Metal-organic framework (MOF) based substrates have great potential for quantitative analysis of hazardous substances using surface-enhanced Raman spectroscopy (SERS) due to their significant signal enhancement, but face challenges like complex preparation, and lack of tunability. Here, we have successfully prepared a well-defined core-satellite superstructure (ZIF-8@Ag) through solvent-induced assembly of silver nanoparticles (Ag NPs) on truncated rhombic dodecahedral ZIF-8. By wisely selecting toluene as the solvent, the assembly process can be easily initiated through ultrasonic treatment and it allows for precise morphological adjustments to build a range of superstructures with different assembly densities of Ag NPs feed ratio tuning.

Nano-Metal-Organic Frameworks Isolated in Mesoporous Structures.

School of Chemistry and Chemical Engineering, Testing Center, Yangzhou University, Yangzhou, 225009, P. R. China.

As an alternative to bulk counterparts, metal-organic framework (MOF) nanoparticles isolated within conductive mesoporous carbon matrices are of increasing interest for electrochemical applications. Although promising, a "clean" carbon surface is generally associated with poor compatibility and weak interactions with metal/ligand precursors, which leads to the growth of MOFs with inhomogeneous particle sizes on outer pore walls. Here, a general methodology for in situ synthesis of eight nanoMOF composites within mesochannels with high dispersity and stability are reported.

2D monolayer electrocatalysts for CO electroreduction.

Nanoscale

January 2025

Institute of Energy Power Innovation, North China Electric Power University, 2 Benigno Road, Beijing 102206, P. R. China.

The electrocatalytic carbon dioxide reduction reaction (CORR) is an attractive method for converting atmospheric CO into value-added chemicals and fuels. In order to overcome the low efficiency and durability that hinder its practical application, a significant amount of research has been dedicated to designing novel catalysts at the nanoscale and even the atomic scale. Two-dimensional (2D) monolayer materials inherit the merits of both 2D materials and single-atom materials.
