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 Scientific reportsThe influence of HKUST-1 and MOF-76 hand grinding/mechanical activation on stability, particle size, textural properties and carbon dioxide sorption.PMC11224341SK-CZ-RD-21-00682/0112/22SGS09/PŘF/2024LUASK22049Bednarcik JBures RZelinska MKiraly NBalaz MZelenka TZauska LSharda PVyhlidalova JFerova MKiralyova ABadac AAlmasi MDiko PfalseThe influence of HKUST-1 and MOF-76 hand grinding/mechanical activation on stability, particle size, textural properties and carbon dioxide sorption.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.
