A novel doubly interpenetrated indium-organic framework of 1 has been assembled by In3+ ions and highly conjugated biquinoline carboxylate-based bitopic connectors (H2L). The isolated exhibits an anionic possessing channel-type apertures repleted with exposed quinoline N atoms carboxyl O atoms. Owing to the unique architecture, displays a durable photoluminescence effect fluorescence quenching sensing toward CrO42–, Cr2O72–, Cu2+ reliable selectivity anti-interference properties, fairly high detection sensitivity, rather low limits. Ligand-to-ligand charge transition (LLCT) was identified as essential cause luminescence modeling ground state excited states using DFT TD-DFT. In addition, negatively charged ability rapidly capture single cationic MB, BR14, or BY24 their mixture, including talent trap MB from (MB + MO) system selectivity. Moreover, intrinsic light absorption capacity band structure feature endow effective photocatalytic decomposition reactive dyes RR2 RB13 under ultraviolet light. Notably, after further polishing constructing S-scheme heterojunction In2S3/1, efficient detoxification Cr(VI) degradation have fully achieved visible This finding may open new avenue for designing multifunctional MOF-based platforms address some intractable environmental issues, i.e., heavy metal ions, physical pony-sized dyes, photochemical decontamination ultrastubborn toxic water.

Metal–Organic Framework-Derived Hierarchical Ag/Sr₆Bi₂O₉-α-Bi₂O₃ Ternary Photocatalyst for Micropollutant Remediation and Bacterial Photoinactivation

ACS Applied Engineering Materials, Год журнала: 2024, Номер 2(1), С. 179 - 194

Опубликована: Янв. 17, 2024

In this work, a hierarchical Ag/Sr6Bi2O9-α-Bi2O3 (Ag/SBO-BO) ternary heterostructure photocatalyst was fabricated by an MOF-derived route and studied for aqueous-phase micropollutant remediation inactivation of water pathogens. The as-synthesized composite inherited the cuboidal-rod shape morphology pristine Bi-MOF with internal hollow structure. Ag nanodots (3–5 nm) were preferentially decorated over planar surface high-aspect-ratio Sr6Bi2O9 nanosheets, which epitaxially grown porous Bi2O3 (BO)-microrods. Ag/SBO-BO displayed important structural attributes including anionic vacancies formation tight heterojunction between Sr6Bi2O9/Bi2O3 (SBO-BO) phases, endowed superior optical absorption, synergistic charge channelization, higher photoexcited state lifetimes. improved optoelectronic features successfully exploited enhanced photocatalytic antibiotic degradation (ciprofloxacin, k = 0.0116 min–1), heavy-metal reduction (Cr6+, 0.0752 pathogens (Vibrio cholerae, 96.5% in 40 min). biocompatible nature also ascertained from hemagglutination study. An S-scheme transfer mechanism promoted plasmonic hot electron injection coupled robust •OH radical generation ability accounted observed photoantibacterial activity composite.
