Abstract Photodriven nonoxidative coupling of CH 4 (NOCM) is an attractive potential way to use abundant methane resources. Herein, n‐type doped photocatalyst for NOCM created by doping single‐atom Nb into hierarchical porous TiO 2 –SiO (TS) microarray, which exhibits a high conversion rate 3.57 μmol g −1 h with good recyclability. The dopant replaces the 6‐coordinated titanium on (1 0 1) plane and forms shallow electron‐trapped surface polarons along [0 1 0] direction comparison different...
The high inertness of the C–H bond makes photocatalytic methane conversion a significant challenge. platinum nanoparticle is promising cocatalyst for CH4 activation, while study its structure characteristics and functionality remains in infancy. Herein, size effect Pt on nonoxidative efficiency was systematically investigated over x-Pt/Ga2O3 with particle (x) ranging from 1.5 to 2.7 nm, where volcano-shaped relation observed. smaller beneficial formation Ptδ+ species, which mainly...

Amorphous MoO3-x nanosheets were fabricated by the room-temperature oxidation of molybdenum powder with H2 O2 , followed light-irradiation reduction in methanol. When applied as a substrate for surface-enhanced Raman spectroscopy (SERS), these exhibit higher sensitivity than crystalline counterpart wide range analytes. Moreover, SERS activity remains stable on repeated oxygen insertion/extraction. In contrast, performance continuously deteriorates successive redox treatments. This unique...
In view of the practical application, it is imperative to develop efficient, exercisable, and visible light driven water pollution treatment materials. Herein, a high-efficiency green photocatalytic membrane for proposed fabricated conveniently. Firstly, silver phosphate (Ag3PO4) nanoparticles with controlled morphology were prepared by simple liquid-phase precipitation method, then hierarchical structured Ag3PO4@polylactic acid (PLA) composite nanofiber was electrospinning. Using...
The dual (pH- and temperature-) responsive core-shell structured mesoporous nanomaterial [email protected] were prepared using bimodal silica as a core poly(N-isopropylacrylamide-co-acrylic acid) P(NIPAM-co-AA) copolymer shell. Ibuprofen (IBU) was used model drug, the effects of copolymer-coated shell thickness on drug loading controlled release behavior investigated by means N2 sorption isotherms, dynamic light scattering measurements, X-ray diffraction patterns, Fourier transform infrared...
Ibuprofen was encapsulated into pH-sensitive hybrid nanocomposite using amine-modified bimodal mesopores silica (BMMs) as core and poly(methylacrylic acid) (PMAA) the shell. The various characterizations showed that PMAA-coated shell played a pH-dependent "open–close" switch, BMMs stored drug carrier. high loading pH-responsive release performances in vitro could be successfully monitored by SAXS techniques, demonstrating evolution of mass fractal with surface roughness structural...

Moreover, experimental data successfully correlated Apelblat empirical equation. thermodynamic properties solution process,...
The self-energy corrections to phonons have mostly been observed for modes with zone-center ($q=0$) wave vectors. Here, we investigated the in ionic-liquid-gated semiconductors, i.e., monolayer and bilayer ${\mathrm{WS}}_{2}$, experimentally. Apart from previously ${A}_{1g}(\mathrm{\ensuremath{\Gamma}})$ mode renormalization by Raman spectroscopy, additionally discovered that zone-edge longitudinal acoustic (LA($M$)) phonon also softened under finite electron doping. This effect arises...
The amorphous MoO3−x nanosheet exhibits more sensitive and stable surface-enhanced Raman spectroscopy (SERS) activity than the crystalline counterpart. signal is under repeated oxygen insertion/extraction condition, which allows recycling of substrate through H2O2-based Fenton-like reaction. More importantly, interference-free operando monitoring photocatalytic p-nitrothiophenol reduction by loaded Pt nanoclusters can be accurately attained UV irradiation using methanol as hole capturer....
Abstract The efficient C-H polarization is the prerequisite for low-temperature photocatalytic CH 4 conversion, which however restricted by poor stretching ability of short-distanced lattice atoms.
