Polymer-embedded metal nanoparticles are in great demand owing to their unique features, leading use various important applications, including catalysis reactions. However, particle sintering and aggregation serious drawbacks, resulting a drastic loss of catalytic activity recyclability. Herein, reduction-immobilizing strategy polymer-embedded sub-2 nm Cu offered highly controlled distribution nanoparticle size within polymer structures with high fidelity. This work sheds light on the performance that rely ultrasmall uniform structures, generating more active sites result efficiency reduction organic compounds. A study was carried out for hydrogenation nitro compounds, achieving nearly 100% an extremely short time remaining stable after 15 consecutive cycles. Furthermore, mechanism demonstrated by density functional theory (DFT) calculations. Notably, discovery this facile may enable remarkable cutting-edge design catalyst materials promising stability.

Copper Nanoparticles Coupled with Fine-Powdered Active Carbon-Modified Ceramic Membranes for Improved Filtration Performance in a Membrane Bioreactor

Water, Год журнала: 2023, Номер 15(23), С. 4141 - 4141

Membrane fouling is a key factor limiting the application of membrane bioreactor (MBR), and membrane-surface modification holds potential to control solves this problem. In research, novel nanocomposite membranes were designed fabricated using antimicrobial copper nanoparticles (CuNPs) coupled with powdered active carbon (PAC) mitigate fouling. The successful coating was confirmed by SEM, XRD, FTIR analysis. Compared pristine membrane, functionalization CuNPs PAC improved hydrophilicity modified but led lower permeate flux. result adhesion experiments showed that M-CuOC displayed high antibacterial activity bacteria count decreased 72%. MBR operation, leads removal efficiency chemical oxygen demand (COD) increasing 93%, better filtration performance under TMP rise. fouling-resistance analysis demonstrated that, although intrinsic resistance slightly increased, reversible irreversible resistances obviously 45% 90%. Moreover, flux recovery also increased 35%. Overall, these results indicated in addition an improvement antifouling performance, enhanced efficiency, revealing good practical application.
