Adhesion lithography (a-Lith) is a versatile fabrication technique used to produce asymmetric coplanar electrodes separated by a <15 nm nanogap. Here, we use a-Lith to fabricate deep ultraviolet (DUV) photodetectors by combining coplanar asymmetric nanogap electrode architectures (Au/Al) with solution-processable wide-band-gap (3.5-3.9 eV) p-type semiconductor copper(I) thiocyanate (CuSCN). Because of the device's unique architecture, the detectors exhibit high responsivity (?79 A W-1) and photosensitivity (?720) when illuminated with a DUV-range (peak = 280 nm) light-emitting diode at 220 muW cm-2. Interestingly, the photosensitivity of the photodetectors remains fairly high (?7) even at illuminating intensities down to 0.2 muW cm-2. The scalability of the a-Lith process combined with the unique properties of CuSCN paves the way to new forms of inexpensive, yet high-performance, photodetectors that can be manufactured on arbitrary substrate materials including plastic.

Imaging Raman spectroscopy is explored as a new tool for in situ studies of electrochemical systems. The technique provides a spatially resolved view of molecular species present along a focused laser line. The capabilities of our system are demonstrated using an electrodeposited thin film of CuSCN plated on a cylindrical platinum electrode. It is shown that line-imaging Raman spectroscopy is able to measure the properties of the thin film deposit while simultaneously monitoring the concentration of solution species within ? 1 mm of the surface. The Raman image presented here has a spatial resolution of ?6 mum and a spectral resolution of 24 cm-1, though neither constitutes resolution limits of the instrument.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 1111-67-7, you can also check out more blogs aboutRelated Products of 1111-67-7

Single-crystal X-ray studies have defined the structures of a number of novel adducts of the form CuX:dpex (2:1), X = (pseudo-)halide, dpex = bis(diphenylpnicogeno)alkane, Ph2E(CH2)xEPh2, E = P, As, of diverse types, solvated with acetonitrile. CuBr:dpem (2:1)2. 2MeCN (E = both P, As) are tetranuclear, derivative of the familiar ‘step’ structure, while CuCl:dpph (MeCN solvate) and CuBr:dppe (MeCN solvate) yield one-dimensional polymers (i.e., x = 1, 2, 6 for dppx, x = m, e, h), as also does CuSCN:dpam (MeCN solvate). In CuI:dpsm:MeCN (3:1:2) (‘dpsm’ = Ph2Sb(CH2)SbPh2), CuI:dpsm (2:1)2 ‘step’ units are connected into an infinite ‘stair’ polymer by interspersed (MeCN)CuI linkers.

CuSCN thin films (optimized previously for perovskite photovoltaics) are deposited on glass, F:SnO2 (FTO), Au, glass-like carbon (GC), and reduced graphene oxide (rGO). They exhibit capacitive charging in an electrochemical window from ca. -0.3 to 0.2 V vs Ag/AgCl. Outside this window, CuSCN film is prone to chemical and structural changes. Anodic breakdown (at ca. 0.5 V) causes restructuring into submicrometer particles and denuding of the substrate. The natural p-doping is demonstrated by both the Hall effect and Mott-Schottky plots from electrochemical impedance. The corresponding flatband potentials (in V vs Ag/AgCl) varied with the substrate type as follows: 0.12 V (CuSCN@FTO), 0.08 V (CuSCN@Au), -0.02 V (CuSCN@GC), and 0.00 V (CuSCN@rGO). The acceptor concentrations determined from electrochemical impedance spectroscopy are by orders of magnitude larger than those from electrical conductivity and the Hall effect, the latter being regarded correct. Raman spectra confirm that thiocyanate is the dominating structural motif over the isomeric isothiocyanate. In situ Raman spectroelectrochemistry discloses substrate-specific intensity changes upon electrochemical charging. The blocking function is tested by a newly designed redox probe, Ru(NH3)63+/2+. It not only has the appropriate redox potential for testing of the CuSCN films but also avoids complications of the standard “ferrocyanide test” which is normally used for this purpose. The perovskite solar cells exhibit better solar conversion efficiency, fill factor, and open-circuit voltage for the rGO-containing devices, which is ascribed to a larger driving force for the hole injection from CuSCN into rGO.

The hexagonal copper-tin alloy (Cu-Sn) nanoplates were synthesized using a high temperature solvent method, the length of six equilateral edges of hexagonal Cu-Sn nanoplates was 23 nm, and the thickness was 13 nm. The obtained hexagonal Cu-Sn nanoplates were highly monodisperse and allowed the formation of nanoarrays arranged with long-range order. The hexagonal Cu-Sn nanoplates exhibited high catalytic activity on catalytic hydrogenation of 4-nitrophenol to 4-aminophenol. Due to the promotion effect of Sn, the apparent rate constant (ka) of hexagonal Cu-Sn nanoplates was three times that of Cu nanoparticles. The density functional theory (DFT) calculations and experimental results demonstrated that Sn could promote the coordination process of -NO2 of 4-nitrophenol with Cu-Sn nanoplates and contribute to activation of 4-nitrophenol. In addition, the hexagonal Cu-Sn nanoplates showed high stability and reusability for the reduction reaction, good adaptability in different pH and the ionic strength, and wide applicability for the degradation of methylene blue, methyl orange, and rhodamine B, even in the industrial wastewater, suggesting that the Cu-Sn nanoplates are promising catalysts in organic industry wastewater treatment.

Supported PdCu catalysts prepared from layered double hydroxides (LDHs) as precursors were evaluated in the gas phase reaction of acetone with hydrogen to methyl isobutyl ketone (MIBK). Two series of catalysts containing ca. 0.2 wt.% Pd and various amounts of Cu (Cu/Pd molar ratio of ca. 0.25, 0.5 and 1) were elaborated according to different methods. One series of precursors was obtained by impregnation of calcined Mg(Al)O mixed oxide with heterobinuclear Pdx Cu1-x acetylacetonates. A second series of precursors was synthesized by coprecipitation of Mg/Pd/Cu/Al LDHs. After calcination, both series were reduced at 473 K. The extends of basic, acid and metal functions were evaluated through microcalorimetric adsorption of CO2, TPD of NH3 and TPR of H2. It was found that the multifunctional transformation of acetone to MIBK was rate determined by the basic function. However, the way by which the catalysts were prepared, impregnation or coprecipitation, controls the extend of hydrogenated by-products, isopropyl alcohol and 4-methyl-2-pentanol. The extensive dilution by migrating MgAlOx species onto the metallic particles makes the coprecipitated catalysts highly selective by decreasing selectively the rate of C=O bond hydrogenation.
