Herein, hierarchically porous NH2-MIL-53(Al) nanorods were synthesized through a straightforward one-pot solvothermal approach, featuring inherently interconnected micro-\/mesoporous with an average pore width of 19.51 nm and abundant amino-functionalized active sites. Toward the anionic Direct Scarlet dye, the material delivers a Langmuir maximum adsorption capacity of 694.99 mg\u00b7g\u22121, with its adsorption kinetics and isotherms well described by the pseudo-second-order kinetics and Langmuir isotherm model. Combined spectroscopic, thermodynamic, and diffusion analyses suggest monolayer electrostatic chemisorption between protonated \u2013NH3+ and dye sulfonate groups. The material exhibits favorable reusability, retaining over 85% of its original dye removal efficiency after five adsorption\u2013desorption cycles, and PXRD and SEM results verify well-preserved morphology and crystalline lattice. This work clarifies the intrinsic correlation between structure and adsorption performance of NH2-MIL-53(Al), offering a facile nanoscale pore-tuning strategy for the design and fabrication of high-performance MOF adsorbents.<\/jats:p>","DOI":"10.3390\/nano16181135","type":"journal-article","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T13:04:57Z","timestamp":1789045497000},"page":"1135","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["NH2-MIL-53(Al) with Hierarchical Micro\u2013Mesoporosity for Highly Efficient Capture of Direct Scarlet Anionic Dye: Insights into Structure\u2013Property Correlations"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-9255-8385","authenticated-orcid":false,"given":"Ruiming","family":"Zhao","sequence":"first","affiliation":[{"name":"Center of Analysis and Testing, Guangdong University of Petrochemical Technology, Maoming 525000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"}]},{"given":"Lingling","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Guangdong University of Petrochemical Technology, Maoming 525000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"217688","DOI":"10.1016\/j.ccr.2026.217688","article-title":"MOF@metal-sulfide: Revolutionizing hybrid materials from structural engineering to advanced energy and environmental applications","volume":"556","author":"Borah","year":"2026","journal-title":"Coord.
