Plasmonically driven photocatalytic hydrogen evolution activity of a Pt-functionalized Au@CeO<sub>2</sub> core–shell catalyst under visible light was insightfully investigated for the first time.
We reported a plasmonic photocatalyst consisting of N-CeO<sub>2</sub> supported by N-graphene for light-driven HER, which offered superior performance relative to and CeO<sub>2</sub> catalysts. This could be due the effects excellent conductivity N-graphene.
As a good stabilizer, [BMIM]BF4 ionic liquid (IL) has been successfully utilized to assist preparation of Ag nanoparticles (NPs) decorated on CeO2 supports. The obtained IL-stabilized Ag-CeO2 nanocomposite showed better photocatalytic degradation activity (92%) Auramine O (AO) dye as compared with pure (35%) NPs and IL-free (65%) after 90 min visible light irradiation. improvement could be attributable small size (5 nm) loaded the surface supports large area its (11.11 m2/g). These increase...
Au nanoclusters (2.18 wt%) consisting of a few tens atoms supported nitrogen-doped graphene deliver an impressive hydrogen evolution reaction rate 3.16 μmol mg cat −1 h under visible-light irradiation and high maximum quantum yield 14.3%.
Recently, various attempts have been made for light-to-fuels conversion, often with limited performance. Herein we report active and lasting three-factored hierarchical photocatalysts consisting of plasmon Au, ceria semiconductor, graphene conductor hydrogen production. The Au@CeO2/Gr2.0 entity (graphene outer shell thickness 2.0 nm) under visible-light irradiation exhibits a colossal achievement (8.0 μmol mgcat-1 h-1), which is 2.2- 14.3-fold higher than those binary Au@CeO2 free-standing...
Microsolvation of the neutral, zwitterion, and unconventional zwitterion (formed by proton transfer from thiol to amine group) was performed using PBE1PBE/6-311+G(d,p) calculations. A large sampling configurations clusters involving one six water molecules created analogy glycine through analysis hydrogen-bonding trends. Clusters neutral tautomer are lowest in energy with inclusion up five molecules. With nearly isoenergetic. The while a stable structure when at least molecule is associated...
The rotational spectrum of 2-methylthiazole was recorded using two pulsed molecular jet Fourier transform microwave spectrometers operating in the frequency range 2–40 GHz. Due to internal rotation methyl group, all transitions were split into A and E symmetry species lines, which analyzed programs XIAM BELGI-Cs-hyperfine, yielding a torsional barrier 34.796 75(18) cm−1. This value compared with that found other monomethyl substituted aromatic five-membered rings. 14N quadrupole coupling...
The microwave spectrum of 2,5-dimethylpyrrole was recorded using a molecular jet Fourier transform spectrometer operating in the frequency range from 2 to 26.5 GHz. Only one stable conformer observed as expected and confirmed by quantum chemical calculations carried out complement experimental analysis. two equivalent methyl groups cause each rotational transition split into four torsional species, which is combined with quadrupole hyperfine splittings same order magnitude arising 14N...
Using two molecular jet Fourier transform microwave spectrometers, the rotational spectrum of 2-methylpyrrole was recorded in frequency range from 2 to 40 GHz. From torsional splittings due internal rotation methyl group a barrier height 279.7183(26) cm−1 deduced. Because 14N nucleus, all lines show quadrupole hyperfine structure. The spectra were analysed using XIAM and BELGI-Cs-hyperfine codes. code enabled us reproduce whole data set with root-mean-square deviation 5.6 kHz while could...
Objective: Tax treaties represent an important aspect of the international tax rules many countries, especially in globalizing era. The taxing rights states is one biggest issues cross border transactions because it decides budget revenue deriving from tax. base, base erosion and prevention are topics that have received a lot attention recently Vietnam order to protect government’s for sustainable development goals (SDGs). Method: By analyzing current status Vietnam's double taxation...
Loading metal on N-doped oxides is advantageous to improving catalytic activity.
Abstract The Raman scattering spectra of uranium‐doped Ca 2 CuO 3 were investigated. small doping uranium (≤5%) in this one‐dimensional spin 1/2 chain system induced three new first‐order bands and two multiphonon the structure forbidden phonons. found to agree well with existing theoretical results from ab initio tight‐binding calculation. Among them, 470 665 cm −1 appeared as basic wavenumbers which overtones composed. grain size effect strongly anisotropic was proposed not originate...
