Abstract
In this study, we explore the mechanical treatment of two metal-organic frameworks (MOFs), HKUST-1 and MOF-76, applying various milling methods to assess their impact on stability, porosity, and CO2 adsorption capacity. The effects of different mechanical grinding techniques, such as high-energy ball milling and hand grinding, on these MOFs were compared. The impact of milling time, milling speed and ball size during high-energy ball milling was assessed via the Design of Experiments methodology, namely using a 33 Taguchi orthogonal array. The results highlight a marked improvement in CO2 adsorption capacity for HKUST-1 through hand milling, increasing from an initial 25.70 wt.% (5.84 mmol g-1) to 41.37 wt.% (9.40 mmol g-1), marking a significant 38% increase. In contrast, high-energy ball milling seems to worsen this property, diminishing the CO2 adsorption abilities of the materials. Notably, MOF-76 shows resistance to hand grinding, closely resembling the original sample's performance. Hand grinding also proved to be well reproducible. These findings clarify the complex effects of mechanical milling on MOF materials, emphasising the necessity of choosing the proper processing techniques to enhance their stability, texture, and performance in CO2 capture and storage applications.

Abstract
![]()
Heterogeneous catalysis plays a pivotal role in the preparation
of value-added chemicals, and it works more efficiently when combined
with porous materials and supports. Because of that, a detailed assessment
of porosity and pore size is essential when evaluating the performance
of new heterogeneous catalysts. Herein, we report the synthesis and
characterization of a series of novel microporous Tröger’s
base polymers and copolymers (TB-PIMs) with tunable pore size. The
basicity of TB sites is exploited to catalyze the Knoevenagel condensation
of benzaldehydes and malononitrile, and the dimension of the pores
can be systematically adjusted with an appropriate selection of monomers
and comonomers. The tunability of the pore size provides the enhanced
accessibility of the catalytic sites for substrates, which leads to
a great improvement in conversions, with the best results achieving
completion in only 20 min. In addition, it enables the use of large
benzaldehydes, which is prevented when using polymers with very small
pores, typical of conventional PIMs. The catalytic reaction is more
efficient than the corresponding homogeneous counterpart and is ultimately
optimized with the addition of a small amount of a solvent, which
facilitates the swelling of the pores and leads to a further improvement
in the performance and to a better carbon economy. Molecular dynamic
modeling of the copolymers’ structures is employed to describe
the swellability of flexible chains, helping the understanding of
the improved performance and demonstrating the great potential of
these novel materials.
