Achieving volatile potassium promoted ammonia synthesis via mechanochemistry

open access: yesNature Communications, 2023
Potassium oxide (K2O) is used as a promotor in industrial ammonia synthesis, although metallic potassium (K) is better in theory. The reason K2O is used is because metallic K, which volatilizes around 400 °C, separates from the catalyst in the harsh ...

Direct conversion of aromatic amides into crystalline covalent triazine frameworks by a condensation mechanism

open access: yesCell Reports Physical Science, 2021
Summary: Multiple studies have recently been conducted to develop well-ordered covalent triazine-based frameworks (CTFs). To date, few studies have demonstrated CTFs with high crystallinity using novel synthesis strategies and different building blocks ...

Recent Progress in Porous Fused Aromatic Networks and Their Applications

open access: yesSmall Science, 2021
Porous materials are ubiquitous in nature and play central roles in ecosystems and human life. Porous fused aromatic networks (P‐FANs) are emerging as a new class of porous organic materials, which can be precisely constructed from organic precursors via

Vertical two-dimensional layered fused aromatic ladder structure

open access: yesNature Communications, 2020
Stacking of planar layers composed of flat building blocks in two dimensional materials results in restriction of segmental motion which affects their typical properties, such as sorption or desorption. Here, the authors minimize this confinement using a

Comparative Extraction of Aluminum Group Metals Using Acetic Acid Derivatives with Three Different-Sized Frameworks for Coordination

open access: yesSeparations, 2021
We prepared acetic acid derivatives using three different frameworks, calix[4]arene, alkenyltrimethylol, and trihydroxytriphenylmethane, which differ in the number and size of their coordination sites.

Forming indium-carbon (In–C) bonds at the edges of graphitic nanoplatelets

open access: yesMaterials Today Advances, 2020
Indium (In), one of the soft and malleable post-transition metals, was introduced along the broken edges of graphitic nanoplatelets (GnPs) by mechanochemically ball-milling graphite in the presence of solid state In beads.
