Abstract Single-atom catalysts anchoring offers a desirable pathway for efficiency maximization and cost-saving photocatalytic hydrogen evolution. However, the single-atoms loading amount is always within 0.5% in most of reported due to agglomeration at higher concentrations. In this work, highly dispersed large (>1 wt%) copper were achieved on TiO 2 , exhibiting H evolution rate 101.7 mmol g −1 h under simulated solar light irradiation, which than other photocatalysts reported, addition...
We present a novel approach to the fabrication of advanced polymeric nanocomposites from poly(vinyl alcohol) (PVA) by incorporation PVA-grafted graphene oxide. In this work, we have synthesized oxide (PVA-g-GO) for strong interfacial adhesion (GO) PVA matrix. It was found that mechanical properties were greatly improved incorporating PVA-g-GO. For example, tensile strength and Young's modulus nanocomposite films containing 1 wt % net GO in PVA-g-GO significantly increased 88 150%,...
High activity, high stability, and low cost have always been the pursuit of photocatalyst design development. Herein, a simple method is used to integrate abundant anion vacancies (VS) cation (VZn) on surface ZnS (M–ZnS), deriving VS VZn pairs (vacancy pairs), isolated Zn atoms (Zniso), S (Siso). Abundant vacancy defects fully expose activate atoms, regulate band structure, significantly improve separation photogenerated carriers. M–ZnS endowed with average hydrogen production rate optimal...
Transition metal selenides as electrode materials for supercapacitors are becoming increasingly attractive, and effective modification strategies improving their practical energy storage performance highly desired. Herein, a dual strategy combined with surface laminating introducing cation vacancies is utilized to optimize the polynary transition selenide CoNiSe2 in atomic levels. The as-obtained sample CNVS/rGO possesses well-developed chemical properties, optimized electron state, more...

SnO2 has been a commonly researched gas-sensing material due to its low cost, good performance, and stability. However, gas sensors based on pure usually show response or high working temperature. In this work, laminar was obtained by using Sn-based metal organic framework(Sn-MOF)@SnO2 as precursor. Sn-MOF@SnO2 is prepared at temperatures water dimethylformamide solvent, which simple, easily reproducible. After sintering, derived with rich adsorbed oxygen, large specific surface area, unique...

Abstract A novel approach to chemically functionalize multiwalled carbon nanotubes (MWCNTs) for making advanced polymeric nanocomposites with liquid crystalline polymers (LCPs) is presented. In this approach, two types of chemical moieties (i.e., carboxylic and hydroxyl benzoic acid groups) are selectively introduced onto the sidewalls MWCNTs. Fourier transform IR Raman spectroscopy used examine interaction between functionalized MWCNTs LCP. The strong LCP greatly improved dispersion in...
Air quality around the globe is declining and public health seriously threatened by indoor air pollution. Typically, pollutants are composed of a series volatile organic compounds (VOCs) that generally harmful to human body, especially VOCs with low molecular weights (less than 100 Da). Moreover, in some situations, more one type VOC present; thus, device can detect or simultaneously would be most beneficial. Here, we synthesized sensor array 4 units VOCs: acetone (unit 1), benzene 2),...
Graphene quantum dots (GQDs) are becoming one of the hottest advanced functional materials because opening bandgap due to confinement effect, which shows unique optical and electrical properties. The chlorine doped GQDs (Cl-GQDs) have been fabricated by chemical exfoliation HCl treated carbon fibers (CFs), were prepared from degreasing cotton through an annealing process at 1000 °C for 30 min. Raman study that both G 2D peaks may be redshifted (softened) doping, leading n-type doping. first...

Printable triple mesoscopic structures for organic–inorganic hybrid perovskite solar cells (PSCs) have recently obtained significant attention, and they possess a superior long-term stability in comparison to those of planar structured PSCs. In with structures, however, typically show lower open-circuit voltages (Voc). Evidence suggests that nonradiative recombination governed by the mismatched energy levels between film electron-transporting layer (or hole-transporting layer) is main cause...
