ZnCo Bimetallic Macro-Microporous Metal–Organic Frameworks for Efficient Adsorption of Dyes

Langmuir, Journal Year: 2025, Volume and Issue: 41(6), P. 4005 - 4015

Published: Feb. 10, 2025

The significant threat posed by dye wastewater has driven the development of efficient adsorbents, such as metal organic frameworks (MOFs). Specifically, we explore synthesis and application ZnCo-based bimetallic zeolite imidazolate with a macro-microporous structure (SOM-ZnCo-ZIF), which exhibit enhanced adsorption capacity for dyes due to their large specific surface area ordered porous arrangement. When SOM-ZnCo-ZIF is immersed in DMA solutions methylene blue, methyl orange, crystal violet, rhodamine B, its high synergistic effect ZnCo clusters, significantly enhances adsorption. Notably, Rhodamine B reaches an impressive 6798.9 mg/g, within just 1 min, 0.5 g/L can remove over 97% from 60 mg/L solution. Moreover, it maintained 92.8% removal efficiency ten cycles without regeneration, demonstrating effective SOM-ZnCo-ZIF. Density functional theory calculations have shown that energy ZIF approximately twice single metal. exhibits strong mainly structure, provides larger pore sizes (∼250 nm) allowing molecules infiltrate network, ability facilitate π-π stacking interactions between benzene rings imidazole ZIF. Additionally, interaction further coordination bonds electrostatic cationic negatively charged framework. This work not only proposes adsorbent but also valuable insights rational design environmentally sustainable MOF structures.

Strong interaction between plasmon and topological surface state in Bi ₂ Se ₃ /Cu _{2- x} S nanowires for solar-driven photothermal applications

Science Advances, Journal Year: 2025, Volume and Issue: 11(11)

Published: March 12, 2025

Developing high-performance photothermal materials and unraveling the underlying mechanism are essential for applications. Here, performance improved by strong interaction between plasmon topological surface state (TSS) is demonstrated in Bi 2 Se 3 /Cu 2- x S nanowires. This hybrid, which Cu nanosheets were grown on nanowires, leverages resonance TSS-induced optical property, generating wide efficient light absorption. A series of tests reveals coupling, hot electron injection, plasmon-induced hole relaxation within hybrids, endowing with excellent performance. By integrating hybrids into a hydrogel thermoelectric module, evaporator achieves remarkable water evaporation rate 3.67 kilograms per square meter hour solar-to-vapor efficiency 95.2%, maximum output power 1.078 watts under simulated sunlight irradiation. Moreover, conical mirror was introduced to device, greatly enhances without additional energy input.

ABSTRACT The strategic design and synthesis of photothermal/photocatalytic materials are pivotal to realizing photothermal conversion water evaporation coupled with photocatalytic sewage purification functions. In this work, based on the principle three primary colors, brick‐red g‐C 3 N 4 /Ag 2 CrO composite was loaded onto a green polyurethane (PU) sponge using polyvinyl alcohol (PVA) as linking agent. resultant PU/PVA/g‐C exhibits outstanding performance in simultaneous evaporation, pollutant degradation, sterilization, thermoelectric generation. Under 1.0 kW m −2 irradiation, rate reaches 3.19 kg h −1 , while single module generates maximum output power 0.25 W . Concurrently, rhodamine B (RhB) at concentration 4.0 × 10 −4 mol L undergoes complete degradation within 40 min. When light intensity is 2.0 soars 8.52 increases 1.1 Furthermore, material colors has excellent antibacterial activity against Escherichia coli By abandoning black light‐absorbing materials, more active sites photocatalyst can be exposed. heterojunction accelerates separation photogenerated carriers, hydrophilic groups reduce enthalpy. This research provides novel approach for fabricating multi‐function which could quicken development solution freshwater electricity energy shortages well environmental pollution issues.
