Photocatalysts possessing high efficiency in degrading aquatic organic pollutants are highly desirable. Although graphene-based nanocomposites exhibit excellent photocatalytic properties, the role of graphene has been largely underestimated. Herein, photothermal effect is demonstrated to play an important enhanced performance, which not considered previously. In our study on degradation (methylene blue), contribution caused by a nanocomposite consisting P25 and reduced oxide can be as ∼38%...
The oxygen evolution reaction (OER) underpins many aspects of energy storage and conversion in modern industry technology, but which still be suffering from the dilemma sluggish kinetics poor electrochemical performance. Different viewpoint nanostructuring, this work focuses on an intriguing dynamic orbital hybridization approach to renormalize disordering spin configuration porous noble-metal-free metal-organic frameworks (MOFs) accelerate spin-dependent OER. Herein, we propose...
Glycine was adsorbed on the surface of a well-defined silica from aqueous solutions variable concentrations and pHs. The molecules were characterized using middle-IR UV−vis−NIR spectroscopies. Except at lowest pH (2.0), they predominantly present as zwitterions. Two successive deposition mechanisms evidenced with increasing glycine concentration. At low concentrations, is specifically sites, probably through its NH3+ moiety. dependence suggests that these sites may be silanolate groups...
Solar steam generation provides a renewable and environmentally friendly approach to solve the water shortage issue. The pursuit of efficient, stable, cheap photothermal agents is thus great significance. In this work, Cu nanoparticles (NPs) fabricated simply by substitution reaction, exhibit near-unity (∼97.7%) light absorption, covering broad incident angle wavelength range (200–1300 nm). Thereby, high conversion efficiency 93% achieved. excellent performance offers unique opportunity for...
We synthesized the hydrogenated cagelike TiO2 hollow spheres through a facile sacrificial template method. After hydrogenation treatment, disordered surface layer and pores were generated on shell of spheres. The exhibit high hydrogen evolution rate 212.7 ± 10.6 μmol h–1 (20 mg) under simulated solar light irradiation, which is ∼12 times higher than solid ∼9 original activity results from unique architectures hydrogenation. Both multiple reflection that was improved by structures red shift...
Fe2O3 is a promising semiconductor for photoelectrochemical (PEC) water decomposition. However, severe charge recombination problems limit its applications. In this study, F–Fe2O3–x/MoS2 nanorod array photoanode was designed and prepared to facilitate separation.

Our results reveal that it feasible to promote...
The stability and catalytic activity of acidic oxygen evolution reaction (OER) are strongly determined by the coordination states spatial symmetry among metal sites at catalysts. Herein, an ultrafast evaporation technology to rapidly soften intrinsic covalent bonds using ultrahigh electrical pulses is suggested, in which prospective charged excited this extreme avalanche condition can generate a strong electron-phonon coupling evaporate some coordinated (O) atoms, finally leading...
The formation and regulation of magnetism dependent on introduced defects in the Janus MoSSe monolayer has attracted much attention because its potential application spintronics. Here, we present a theoretical study defect under external strain. tensile deformation induced by strain not only leads to decreases energy, but also enhances magnetic characteristics. However, as compressed increases, structure Se or S remains unchanged this microstructural adequately spin polarizes unpaired...
An electrochemical method to prepare two-dimensional (2D) layered black phosphorus oxide with an inhomogeneous and non-stoichiometric structure is developed described. The localized oxygen-related electronic states induce tunable photoluminescence (PL) between 620 670 nm. After oxidation, several new Raman modes frequencies below 300 cm−1 emerge the Ag1 mode splits into two sub-bands. frequency difference sub-bands (Δ) exhibits a monotonic dependence on emission wavelength suggesting that PL...
Dentin bonding is a dynamic process that involves the penetration of adhesive resin monomers into extrafibrillar and intrafibrillar demineralized collagen matrix using wet-bonding technique. However, lack capacity to infiltrate space, excess water introduced by technique remains at interface. This imperfectly bonded interface inclined hydrolytic degradation, severely jeopardizing longevity clinical restorations. The present study introduces dentin scheme based on dry-bonding technique,...
