The mass ratios of CNTs and BiBTC varied from 0 to 2, 5, and 10% (denoted as BiBTC@CNTs-x, x = 0 to 2, 5, and 10). The characteristics of the catalyst were determined by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and diffuse reflectance spectroscopy (UV-Vis DRS). The catalytic activity of the material was tested by photodegradation of rhodamine B. The structure of BiBTC@CNTs-x displayed a UU-200 and CNT structure with rod-shaped interweaving between the CNT fibers. The results indicated that BiBTC@CNTs-2 had the most significant ability to degrade RhB, achieving 98% degradation in 180 min. The increased separation of electron-hole pairs via a built-in electric field between CNT and BiBTC is responsible for the improved photocatalytic degradation of RhB, as observed in the XPS spectrum, transient photocurrent response, electrochemical impedance spectroscopy (EIS), and Mott-Schottky plots. In addition, the catalyst mass, dye concentration, pH of the medium, and radical scavengers were investigated. Furthermore, free radicals (O²⁻) and electrons (e-) played the primary and most influential role in the photocatalytic degradation of both dyes, with a minor contribution from the photogenerated holes (h+).

Yet, the enzymes from nature are engineered to make them adapt and enhance their durability in the industrial environment. One promising approach involves the combined use of multiple enzymes that catalyze highly selective and sequential reactions in a single reaction vessel. The multi-enzymatic biocatalytic systems, achieved through gene fusion, fusion proteins, DNA manipulation and bioconjugation, protein engineering, or attachment to solid support materials for immobilization, such as protein-polymer, silica, metal organic framework, Carbon nanotubes or graphene based hybrids, have found widespread utility across various sectors, including the food industry, wastewater treatment, drug delivery, biosensors and methanol production. Enzyme conjugation enables the creation of novel enzymes with improved kinetics and synergistic effects. Researchers can evolve fusion proteins by fusion enzymes which can evolve novel catalytic activities in Biotechnological processes. These engineered enzymes can contribute in synthetic Biology in construction of synthetic system for various applications. Enzyme conjugation helps in metabolic engineering by optimization of pathways. Researchers can develop pathways for production of Bio-sensors, pharmaceuticals, biofuels and other valuable industrial products.

The effectiveness of multivalent metals as homogeneous or heterogeneous catalysts depends on a variety of variables, including coexistence, pH, formulation, and others. Currently, Fe-based catalysts, such as magnetite, olivine, and ilmenite, have gained interest due to their lower cost, higher reactivity, and stability.

The main greenhouse gas, CO₂, is a major factor in global climate change, which eventually disrupts the delicate balance of ecosystems within the globe. Therefore, the development of effective and sustainable technology for CO₂ capture and storage is both urgent and compelling. Among many different approaches for CO₂ capture, membrane separation has shown to be one of the most promising, yielding excellent results in terms of effectiveness as well as affordability. Nonetheless, to enhance membrane performance more significantly in CO₂ separation, researchers have focused on ionic liquids, a family of organic salts recognized for their high thermal stability, low volatility, and tuneable characteristics. Because of this, ionic liquids have attracted a lot of attention from the academic and industrial sectors as possible additions to enhance membranes’ capacity for CO₂ separation. This study explores the potential of Tetrahexyl tetradecyl phosphonium chloride incorporated into Pebax-1657 to enhance CO₂/CH₄ separation performance. Ion gel membranes were synthesized with varying ionic liquid concentrations (5, 10, 20 wt%) and characterized for structural and morphological evaluations. Gas separation performance was assessed through permeation experiments, showing increased CO₂/CH₄ selectivity from 19.23 to 21.81 with higher IL concentrations, especially under high pressure. CO₂ permeability increased from 70.01 to 273.61 barrer with the addition of 20% [THTDP][Cl]. Density functional theory calculations provided theoretical insights into the interaction energies between ionic liquid and gas molecules, corroborating experimental findings. The study demonstrates the novelty of integrating phosphonium-based ionic liquid with Pebax-1657, significantly enhancing CO₂/CH₄ selectivity due to strong CO₂ interactions. This research offers a promising approach to developing advanced membranes for efficient and selective CO₂ capture, contributing to sustainable gas separation technologies.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"94 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
