We report on the synthesis of fluorinated reduced graphene oxide (F-rGO) by a direct fluorination (rGO) with F2 or XeF2/BF3 in anhydrous HF. Characterization performed high-angle annular dark-field (HAADF)-scanning transmission electron microscopy (STEM) and NMR confirmed formation C–F bonds, which is also supported color change from graphite gray to light yellow. F-rGO has been used as an interlayer additive glass fiber separator lithium–sulfur (Li–S) batteries order block...
The persulfate (PS) activation can be successfully applied in water treatment and the use of carbon materials to activate PS has been thoroughly described literature. Nevertheless, prospect employing a metal-free catalytic membrane as single activator better studied. In present work, graphite oxide was prepared by modified Hummers' method different nitrogen precursors (melamine, urea gaseous ammonia) were investigated produce N-doped graphene catalysts. material with melamine presented...
Abstract A green, template‐free and easy‐to‐implement strategy was developed to access holey g‐C 3 N 4 (GCN) nanosheets doped with carbon. The protocol involves heating dicyandiamide β‐cyclodextrin (βCD) prior polymerization. local symmetry of the GCN skeleton is broken, yielding C x ( corresponds initial amount βCD used) pores a distorted structure. electronic, emission, optical textural properties best‐performing material, C2GCN, were significantly modified as compared bulk GCN....
In the quest for designing efficient and stable photocatalytic materials CO2 reduction, hybridizing a selective noble-metal-free molecular catalyst carbon-based light-absorbing has recently emerged as fruitful approach. this work, we report about Co quaterpyridine complexes covalently linked to graphene surfaces functionalized by carboxylic acid groups. The nanostructured were characterized X-ray photoemission spectroscopy, absorption IR Raman spectroscopies, high-resolution transmission...
The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases ferroelectric materials has been an open question since discovery ferroelectricity oxide perovskites (ABO3). A currently considered model suggests locally correlated displacements B-site atoms along a subset <111> cubic directions. Such offsite have confirmed experimentally, however, being essentially dynamic they cannot account for static symmetry-forbidden polarization implied by...
This study targets one of the grand challenges electrochemical hydrogen production: a durable and cost-effective oxygen-evolution catalyst. We present thin-film composite electrode with unique morphology an ultralow loading iridium that has extraordinary electrocatalytic properties. is accomplished by growth defined, high-surface-area titanium oxide nanotubular film, followed nitridation effective immobilization nanoparticles. The applicative relevance this production process justified high...
The present research provides a study of carbon-supported intermetallic Pt-alloy electrocatalysts and assesses their stability against metal dissolution in relation to the operating temperature potential window using two advanced electrochemical methodologies: (i) in-house designed high-temperature disk electrode (HT-DE) methodology as well (ii) modification flow cell coupled an inductively plasma mass spectrometer (EFC-ICP-MS) methodology, allowing for highly sensitive time-...
Nanoparticulate electrocatalysts for the oxygen reduction reaction are structurally diverse materials. Scanning transmission electron microscopy (STEM) has long been go-to tool to obtain high-quality information about their nanoscale structure. More recently, its four-dimensional modality emerged as a comprehensive crystal structure analysis using large data sets of diffraction patterns. In this study, we track alternations individual carbon-supported PtCu3 nanoparticles before and after...
The polyol method was employed for the first time to synthesize cuprous oxide nanowires using only a precursor of Cu(II) acetate monohydrate and diethylene glycol (DEG). With careful control reaction temperature (190 °C), concentration (0.01−0.1 mol/L), (6 h), we prepared Cu2O with diameter approximately 20 nm length up 5 μm. were characterized by SEM, TEM, XRD, IR spectroscopy.
