The crystallinity was adjusted by varying the solvent volume, yielding an amorphous phase with higher surface area (\u2248242\u2009m\n                    <jats:sup>2\u2009<\/jats:sup>\n                    g\n                    <jats:sup>\u22121<\/jats:sup>\n                    ) and a crystalline form with reduced porosity (\u224822\u2009m\n                    <jats:sup>2\u2009<\/jats:sup>\n                    g\n                    <jats:sup>\u22121<\/jats:sup>\n                    ).

These findings suggest that structural features such as higher surface area, pore volume, and possible disorder contribute to the improved gas sorption and photocatalytic response. The use of mild reaction conditions and a single solvent system offers a straightforward and energy\u2010efficient approach for preparing functional MOFs with tunable crystallinity, applicable in environmental remediation contexts.\n
