Photocatalytic regeneration of a nicotinamide cofactor, adenine dinucleotide phosphate (NADPH), has emerged as an ideal cascade partner for combination with enzymatic transformations, but it still suffers from low efficiency due to the recombination photogenerated charge carriers. Herein, hierarchical Rh-covalent organic framework (COF)@COF core–shell hollow sphere (CSHS) S-scheme heterojunction is proposed enhance carrier transfer and utilization in photocatalysis regenerate expensive...
Magnetic silica composite particles were prepared by using the biosilicification reaction, in which Fe3O4 nanoparticles entrapped a matrix. The functionalized with 3-aminopropyltriethoxysilane (APTES). These magnetic used to immobilize kind of valuable bulky industrial enzyme (laccase). incorporation greatly facilitates manipulation immobilized biocatalyst, since it can be easily and quickly recovered from reaction system simple application an external field. effects immobilization...
Developing a highly efficient and anti-fouling nanofiltration (NF) membrane for the desalination of dye wastewater is one hot environmental issues. In this study, loose NF membranes were facially prepared by glutaraldehyde (GA)-diffused crosslinking zwitterion-functionalized polyethylenimine (PEI-SBMA) subsequent tannic acid (TA) surface modification. The microstructure was tuned optimizing condition to enhance selectivity dye/salt. performance improved functionalization zwitterion...
Although loose nanofiltration membranes have been extensively studied for dye desalination, high-throughput with antifouling and antibacterial properties are still highly needed. In this study, a zwitterion-modified molybdenum disulfide (MoS2) dual-layer membrane was prepared the integration of antibacterial, antifouling, high-flux properties. To be specific, MoS2 nanosheets were loaded on polyacrylonitrile ultrafiltration through pressure-assisted self-assembly. Then, poly (sulfobetaine...
Enzyme catalysis is green and mild, while suffering from being easily damaged by environment. In this work, zirconium-based metal–organic frameworks (Zr-MOFs) were synthesized to replace enzymes prepare an enzyme mimic catalytic membrane for the removal of aqueous organophosphorus pesticides. Polydopamine (PDA) covered substrate strengthen adherence UiO-66-NH2 layer. After optimization, rate model methyl paraoxon (MPO) was 95.12% with functions catalysis, adsorption, rejection,...
The worldwide application of organophosphorus pesticides (OPs) has promoted agricultural development, but their gradual accumulation in soil and water can seriously affect the central nervous system humans other mammals. Organophosphorus hydrolase (OPH) is an effective enzyme that catalyze degradation residual OPs. However, products such as p-nitrophenol (p-NP) still toxic. Thus, it great significance to develop a multi-functional support be simultaneously used for immobilization OPH further...
A three-in-one heterogeneous catalyst (UPO@dTiO2-CD) was fabricated by grafting cyclodextrins (CDs) on the dehiscent TiO2 (dTiO2) surface and subsequently immobilizing unspecific peroxygenase (rAaeUPO), which exhibited double enhanced electron/mass transfer in photo-enzymatic enantioselective hydroxylation of C-H bond. The tunable anatase/rutile phase ratio mesoporous architectures dTiO2 electron donor feature hydrophobic inner cavity CDs are independently responsible for accelerating both...
Abstract BACKGROUND As visible‐light photocatalytic semiconductors, BiOBr‐based catalysts have a promising application prospect for the degradation of dyes and pollutants in wastewater. Enzyme catalysis has become technology organophosphorus due to excellent activity specificity. Herein, photoenzymatic integrated nanocatalyst hydrolase (OPH) immobilized on BiOBr (OPH@BiOBr) was successfully synthesized cascade methyl parathion under visible light. RESULTS The obtained OPH@BiOBr could degrade...
Carbon sources and copper ion are the main influencing factors on production of fungal laccase. To investigate regulation carbon source in laccase molecular level tropical white-rot fungus PG15, a comparative analysis gene expression patterns was performed by cDNA-amplified fragment length polymorphism (AFLP) technique. Selective amplifications with 120 primer combinations allowed identification 92 differentially expressed transcript-derived fragments (TDFs), ranging from 200 to 750 bp size....
Chloroperoxidase (CPO) is promising for the synthesis of sulfoxides from sulfides, owing to its high enantioselectivity and mild reaction conditions. However, suffering stability recyclability issue, application free CPO heavily restricted nowadays. In this work, an integrated photobiocatalyst was designed constructed by immobilizing on a magnetic recyclable photocatalyst, Fe3O4@Cu-H-TiO2, which can supply H2O2 in situ continuously suppress destruction caused excess H2O2. The photoelectronic...
Abstract Photocatalysis is an eco‐friendly method to regenerate nicotinamide (NADH) cofactors, which essential for biotransformation over oxidoreductases. Organic polymers exhibit high stability, biocompatibility and functional designability as photocatalysts, but still suffering from rapid charge recombination. Herewith the heteroatom structural engineering of donor‐π‐acceptor (D‐π‐A) conjugated porous were conducted promote transfer photocatalytic NADH regeneration. The electron...
