MOFTextile: Metal‐organic frameworks nanosheets incorporated cotton textile for selective vapochromic sensing and capture of pyridine

Abstract

Metal–organic frameworks (MOFs) improved several trends and are promising for industrial applications. However, current synthesis processes offer powder form, rendering their applications difficult. A simple solvothermal method offered an in situ growth of copper‐based MOFs, for example, CuBDC (BDC: benzene‐1,4‐dicarboxylic acid) into a cotton textile; the material was denoted as CuBDC@Textile. CuBDCTextile was used as a solid sensor and adsorbent for volatile organic compounds (VOCs). It exhibited good vapochromic properties that enabled a colorimetric detection of pyridine (Py) via naked eyes with high selectivity and good sensitivity. Adsorption of pyridine via pervaporation using CuBDC@Textile was recorded. CuBDCTextile is a flexible textile with a high adsorption capacity (137.9 mg g−1) toward pyridine. It offered dual functional: sensor probe and adsorbent. The synthesis of CuBDC@Textile and their excellent performance as a sensor and adsorbent are promising for further investigation of the “MOFs on textile materials” topic.

Three-Dimensional Printing of Cellulose/Covalent Organic Frameworks (CelloCOFs) for CO2 Adsorption and Water Treatment

“…Natural biopolymers such as cellulose advanced in several applications including water treatment. , TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl)-assisted cellulose nanofibers (TOCNFs) refer to a specific category of cellulose nanofibers that are manufactured by a chemical oxidation technique known as TEMPO oxidation . The aforementioned procedure induces a transformation of the cellulose surface, resulting in a significant increase in the negative charge.…”
