A possible high efficiency working model of a monolayer PEDOT:PSS film and brief fabrication process.
Low efficient transfer of photogenerated charge carriers to redox sites along with high surface reaction barrier is a bottleneck problem photocatalytic H2O overall splitting. Here, in the absence cocatalysts, splitting has been achieved by single-atomic S vacancy hexagonal CdS spin polarization electric field (PEF). Theoretical and experimental results confirm that vacancy-induced PEF opposite direction Coulomb accelerates carrier transport dynamics from bulk phase surface-redox sites. By...
Nanozymes with peroxidase-like activity have been extensively studied for colorimetric biosensing. However, their catalytic and specificity still lag far behind those of natural enzymes, which significantly affects the accuracy sensitivity To address this issue, we design PdSn nanozymes selectively enhanced activity, improves a immunoassay. The is higher than that Pd nanozymes. Theoretical calculations reveal p–d orbital hybridization Sn not only results in an upward shift d-band center to...
The performance of inverted perovskite solar cells is highly dependent on hole extraction and surface properties transport layers. To highlight the important role layers, a facile simple method developed by adding sodium chloride (NaCl) into poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS). average power conversion efficiency prepared NaCl-doped PEDOT:PSS 17.1% with negligible hysteresis, compared favorably to control devices (15.1%). Particularly, they exhibit markedly...
We report that gold thermally deposited onto n-layer graphenes interacts differently with these substrates depending on the number layer, indicating different surface properties of graphenes. This results in thickness-dependent morphologies graphenes, which can be used to identify and distinguish high throughput spatial resolution. technique may play an important role checking if are mixed layer numbers graphene a smaller size, cannot found by Raman spectra. The possible mechanisms for...
The preparation of high-quality perovskite films is important for achieving high-performance solar cells (PSCs). effective balance between solvent and antisolvent an essential factor regulating film during the spin-coating thermal-annealing steps. In this work, a greener, nonhalogenated, nontoxic bifunctional (anti)solvent, methyl benzoate (MB), developed not only as to rapidly generate crystal seeds at step, but also digestive-ripening precursors, which can prevent loss organic components...
The development of organic-inorganic hybrid perovskite materials has been rapid in recent years; but their applications are limited by the toxicity and stability materials. To address these issues context resistive switching devices, an inorganic lead-free namely CsBi3I10 is developed. Uniform pinhole-free thin films can be fabricated using CsI-rich precursor solution via a facile antisolvent-assisted spin-coating method. nonvolatile devices based on demonstrate large on/off ratio (103),...
In this work, we report the layer-dependent fluorination of n-layer graphenes by SF6 plasma treatment. For monolayer graphene, D, D′, and D+G peaks Raman spectroscopy can be clearly observed, whereas these are absent for thicker (n ≥ 2) at same experimental conditions. This indicates that graphene is much more susceptible to being fluorinated than graphenes. These results well explained larger corrugations those Meanwhile, reversible after vacuum annealing. studies provide useful information...
An organocatalytic [3 + 2]-annulation between isatin-derived Morita–Baylis–Hillman adducts and cyclic sulfonimines has been developed in high yields with excellent enantio- diastereoselectivities via an allylic nitrogen-ylide intermediate. The reaction provides access to heavily substituted aza-spirooxindole derivatives, which also contain ring fused sultams.
The requirement for enhanced, less expensive, and eco-friendly nanocomposites as an adsorbent is highly preferred removal of heavy metals in the major applications environmental remediation. For widespread application prospects, a simple cost-effective method effective nanoadsorbent preparation mainly studied. In this study, by using natural polymer chitosan (CS) different iron ion precursors, facile situ one-step coprecipitation synthetic approach used to develop water-dispersible...
After thermal deposition of silver films onto n-layer graphenes, the following results have been obtained. First, dependence morphologies on layer number is studied via controlling sample temperature at 298, 333, and 373 K. This can be attributed to changes in surface properties and/or diffusion coefficient graphenes different temperatures. Second, Raman scattering greatly enhanced after Ag enhancement factors depend graphenes. Monolayer graphene has largest factors, decrease with...
Abstract Efficient activation of hydrogen peroxide (H 2 O ) through biomimetic catalysis still faces a major challenge. In this work, inspired by the catalytic pocket natural peroxidase, Cu single atom (Cu SA and AuCu nanoparticles (AuCu NPs anchored on nitrogen‐doped carbon skeleton ‐AuCu /NC) serve as dual active sites that significantly accelerate charge transfer process thus achieve efficient H activation. Meanwhile, experimental theoretical calculations show well‐established electronic...
Although oxygen reduction reaction (ORR) as an effective signal amplification strategy has been extensively investigated for the improvement of sensitivity electrochemical sensors, their activity and stability are still a great challenge. Herein, single-atom Fe (FeSA) nanoparticles (FeNP) on nitrogen-doped carbon (FeSA/FeNP) catalysts demonstrate highly active stable ORR performance, thus achieving sensitive sensing organophosphorus pesticides (OPs). Experimental investigations indicate that...
