Graphene oxide/TiO2 composites were prepared by using TiCl3 and graphene oxide as reactants. The concentration of in starting solution played an important role photoelectronic photocatalytic performance composites. Either a p-type or n-type semiconductor was formed These semiconductors could be excited visible light with wavelengths longer than 510 nm acted sensitizer Visible-light driven degradation methyl orange also studied. Crystalline quality chemical states carbon elements from...
Co3O4/BiVO4 composite photocatalyst with a p−n heterojunction semiconductor structure has been synthesized by the impregnation method. The physical and photophysical properties of have characterized X-ray diffraction (XRD), photoelectron spectroscopy (XPS), transimission electron microscopy (TEM), BET surface area, UV−visible diffuse reflectance spectra. Co is present as p-type Co3O4 disperses on n-type BiVO4 to constitute composite. exhibits enhanced photocatalytic activity for phenol...
Highly organized arrays of TiO2 nanotubes (as depicted in the figure) are integrated into a thin-cell photoelectrocatalytic reactor for rapid determination chemical oxygen demand wastewater samples. The high photocatalytic activity arises from efficient separation photogenerated electrons and holes, enables fabrication sensors exhibiting good accuracy, stability, reproducibility.
Transition metal catalysts are known to activate persulfate, but the properties that govern intrinsic activity of these still unknown. Here, we developed a series with transition metals anchored on carbon nanotubes (denoted M–N–CNTs, where M = Co, Fe, Mn, or Ni) containing single-atom M–N moieties, peroxymonosulfate for efficient nonradical oxidation sulfamethoxazole. The spin state M–N–CNTs strongly determined their catalytic activity. A large effective magnetic moment high (e.g., Co–N)...
Four-nitrogen-coordinated transitional metal (MN4) configurations in single-atom catalysts (SACs) are broadly recognized as the most efficient active sites peroxymonosulfate (PMS)-based advanced oxidation processes. However, SACs with a coordination number higher than four rarely explored, which represents fundamental missed opportunity for chemistry to boost PMS activation and degradation of recalcitrant organic pollutants. We experimentally theoretically demonstrate here that...
High-valent metal-oxo (HVMO) species are powerful non-radical reactive that enhance advanced oxidation processes (AOPs) due to their long half-lives and high selectivity towards recalcitrant water pollutants with electron-donating groups. However, high-valent cobalt-oxo (CoIV =O) generation is challenging in peroxymonosulfate (PMS)-based AOPs because the 3d-orbital occupancy of cobalt would disfavor its binding a terminal oxygen ligand. Herein, we propose strategy construct isolated Co sites...
Bismuth vanadate (BiVO4) has been considered as a promising photoelectrocatalytic (PEC) semiconductor, but suffers from severe hole recombination, attributed to the short hole-diffusion length and low carrier mobility. Herein, type-II heterojunction CdIn2S4/BiVO4 is designed improve photocurrent density 1.22 (pristine BiVO4) 2.68 mA cm-2 at 1.23 V vs reversible hydrogen electrode (RHE), accelerating bulk separation of photogenerated carriers by built-in field matched energy band. With...
Hydrogen peroxide photosynthesis suffers from insufficient catalytic activity due to the high energy barrier of hydrogen extraction H2O. Herein, we report that mechanochemically synthesized keto-form anthraquinone covalent organic framework which is able directly synthesize H2O2 (4784 μmol h-1 g-1 at λ > 400 nm) oxygen and alkaline water (pH = 13) in absence any sacrificial reagents. The strong alkalinity resulted formation OH-(H2O)n clusters water, were adsorbed on keto moieties within then...
A visible-light driven photocatalytic fuel cell (PFC) system comprised of WO3/W photoanode and Cu2O/Cu photocathode was established for organic compounds degradation with simultaneous electricity generation. The central idea its operation is the mismatched Fermi levels between two photoelectrodes. Under light illumination, level higher than that photocathode. An interior bias can be produced based on which electrons transfer from external circuit to combine holes then generates electricity....
A TiO(2)-nanotube-array-based photocatalytic fuel cell system was established for generation of electricity from various refractory organic compounds and simultaneous wastewater treatment. The present can respond to visible light produce obviously enhanced performance when a narrow band-gap semiconductor (i.e. Cu(2)O CdS) combined with TiO(2) nanotubes.
