Solar-driven photocatalytic H 2 O production with water and is an environmentally friendly process for producing , important chemical.
Photocatalytic hydrogen peroxide (H 2 O ) production from water and has received considerable attention.
Abstract It was shown that some nanomaterials may have anticancer properties, but lack of selectivity is one challenges, let alone selective suppression cancer growth by regulating the cellular microenvironment. Herein, we demonstrated for first time carbon quantum dots/Cu 2 O composite (CQDs/Cu O) selectively inhibited ovarian SKOV3 cells targeting microenvironment, such as matrix metalloproteinases, angiogenic cytokines and cytoskeleton. The result showed CQDs/Cu possessed properties...
Ternary metal sulfide (MIn
Metals-organic frameworks (MOFs) have been widely explored in biomedicine, mostly drug delivery, biosensing, and bioimaging due to their large surface area, tunable porosity, readily chemical functionalization, good biocompatibility. However, the underlining cellular mechanisms controlling process for MOF cytotoxicity remains almost completely unknown. Here, we demonstrate that pristine Cu-MOF without any loaded selectively inhibited ovarian cancer mainly through promoting tubulin...
Pharmaceuticals and personal care products (PPCPs) which include antibiotics such as tetracycline (TC) ciprofloxacin (CIP), etc., have attracted increasing attention worldwide due to their potential threat the aquatic environment human health. In this work, a facile sol-gel method was developed prepare tungsten-doped TiO2 with tunable W5+/W6+ ratio for removal of PPCPs. The influence solvents in synthesis three different tungsten precursors doped is also taken into account. WCl6, ammonium...
Liquid-phase catalytic oxidation of limonene was carried out under mild conditions, and carvone produced in the presence ZIF-67(Co), cobalt based zeolitic imidazolate framework, as catalyst, using t-butyl hydroperoxide (t-BHP) oxidant benzene solvent. As a heterogeneous framework ZIF-67(Co) exhibited reasonable substrate–product selectivity (55.4%) conversion (29.8%). Finally, X-ray diffraction patterns catalyst before after proved that acted can be reused without losing its activity to great extent.
Nitrogen doping in combination with the brookite phase or a mixture of TiO2 polymorphs nanomaterials can enhance photocatalytic activity under visible light. Generally, nitrogen-dopedanatase/brookite mixed phases nanoparticles obtained by hydrothermal solvothermal method need to be at high temperature and long time heating treatment. Furthermore, surface areas them are low (<125 m2/g). There is hardly report on simple direct preparation N-doped anatase/brookite nanostructures using...
In sharp contrast to conventional photosensitization methods in which the organic pigments were often adsorbed, herein we present a study on natural vegetable pigment inserted TiO2 aerogel nanocomposites and directly use red cabbage anthocyanin (RCP) as structure-directing agent. It was found that pure nanocomposite did not exhibit any meaningful activity for photocatalytic reduction of Cr(VI). However, greatly improved by RCP under visible-light irradiation, approximately 2- 12.3-fold...
Abstract Whereas a variety of inorganic nanomaterials possessing intrinsic peroxidase‐like activity have recently attracted considerable interest, little attention is given to explore their protease‐mimic activities. And the construction efficient enzyme mimetics for hydrolysis peptide bonds in proteins still represents major technical challenge due high stability and importance proteases biology industry. Herein, it described first time that Cu 2 O‐decorated carbon quantum dots (CQDs/Cu O)...
The treatment of hospital wastewater at full scale (60m3/day), was newly developed combining many processes including activated sludge, coagulation-flocculation, and skid-mounted photocatalysis. tested raw had the following characteristics: biochemical oxygen demand (BOD): 250~400 mg/L, chemical (COD): 800~1000 ammonia nitrogen (NH3-N): 70~100 total phosphorus (TP): 3.0~5.0 suspended solids (SS): 200~300 mg/L fecal coliforms (FC): 9.2×104~1×105 MON/L. During more than 3-years in situ...
In this work, metal-organic frameworks (MOFs) Fe-MIL-101 was synthesized by hydrothermal method, and Fe/Fe-MIL-101 with different loadings prepared. The crystal structure of the sample characterized scanning electron microscopy (SEM), X-ray diffraction (XRD) specific surface area measurement (BET). found to posses an intrinsic enzyme mimicking activity similar that in natural horse-radish peroxidase (HRP). Michaelis constant (Km) 5% ABTS as substrate is about 10-fold smaller than 3-fold HRP,...
