There is an overwhelming desire to develop new sulfide oxidation electrocatalysts that perform at low potentials and exhibit high current density for the removal and efficient sensing of sulfide. This article describes a comparative electrochemical analysis of various commercially available carbon materials and polymer/surfactant composite electrocatalysts for direct electrooxidation of sulfide in an aqueous solution. The composites were prepared from five different carbon materials multiwalled carbon nanotubes, fullerene‐C60, graphene, glassy carbon, and carbon nanofibers (CNF) and four different polymers: chitosan, polyvinylidene fluoride, Nafion, and indigenously synthesized poly[2‐(methacryloyloxy)ethyl] trimethylammonium chloride (PMTC). The carbon@polymer composites were prepared by a simple ultrasonication technique, and the electrodes were prepared by drop‐drying the prepared composite on indium tin oxide (ITO) substrates. The CNF@PMTC showed the highest positive zeta potential that allowed an accumulation of many negatively charged sulfide ions at the CNF@PMTC surface. Cyclic voltammetry was used for the electrooxidation of sulfide in an aqueous solution of tris buffer (0.05 M; pH 8.0) and KNO3 (0.1 M). The lowest sulfide oxidation peak potential (i. e., −51 mV vs. standard hydrogen electrode) with a high catalytic current response (730 μA/cm2) of the CNF@PMTC‐modified ITO electrode among the tested and previously reported carbon‐based electrode materials make it ideal for direct sulfide electrooxidation. Taking this and its simple preparation method into account, CNF@PMTC can be considered a benchmark carbon‐based electrocatalyst for sulfide oxidation.

“…The XRD pattern of BCN NSs displayed two characteristic bands at around 25° and 44°, which typically represent the 002 and 101 interlayer reflections of the BCN, respectively . On the other hand, the XRD pattern of F/BCN nanohybrids showed several diffraction peaks at around 10.83°, 17.72°, 20.76°, 21.70°, 27.56°, 28.23°, 30.94°, and 32.86°, which correspond to the (111), (220), (311), (222), (331), (420), (422), and (511) diffraction planes of F, respectively, in addition to showing the diffraction pattern of BCN as well. , Upon the interaction of F with BCN NSs, the BCN diffraction peak (002) is slightly shifted to ∼25.5°. The XRD spectra of all F/BCN nanohybrids in Figure B show a higher degree of crystallization, suggesting a good charge mobility as well as electrochemical stability.…”

Tuning the Intermolecular Electron Transfer of Low-Dimensional and Metal-Free BCN/C₆₀ Electrocatalysts via Interfacial Defects for Efficient Hydrogen and Oxygen Electrochemistry

The development of low-dimensional (LD) supramolecular materials with multifunctional electrocatalytic properties has sparked the attention of the catalysis community. Herein, we report the synthesis of a new class of 0D−2D heterostructures composed of boron carbon nitride nanosheets (BCN NSs) and fullerene molecules (C 60 /F) that exhibit multifunctional electrocatalytic properties for the hydrogen evolution/oxidation reactions (HER/HOR) and the oxygen evolution/reduction reactions (OER/ORR). The electrocatalytic properties were studied with varying F:BCN weight ratios to optimize the intermolecular electron transfer (ET) from the BCN NSs to the electron-accepting C 60 molecules. The nanohybrid supramolecular material with 10 wt % F in BCN NSs (10% F/BCN) exhibited the largest Raman and C 1s binding energy shifts, which were associated with greater cooperativity interactions and enhanced ET processes at the F/BCN interface. This synergistic interfacial phenomenon resulted in highly active catalytic sites that markedly boosted electrocatalytic activity of the material. The 10% F/BCN showed the highest tetrafunctional catalytic performance, outperforming the OER catalytic activity of commercial RuO 2 catalysts with a η 10 of 390 mV and very competitive onset potential values of −0.042 and 0.92 V vs RHE for HER and ORR, respectively, and a current density value of 1.47 mA cm −2 at 0.1 V vs RHE with an ultralow ΔG H* value of −0.03 eV toward the HOR process. Additionally, the 10% F/BCN catalyst was also used as both cathode and anode in a water splitting device, delivering a cell potential of 1.61 V to reach a current density of 10 mA cm −2 .

A facile process has been developed for the encapsulation of fish oil using a thin film vortex fluidic device (VFD) operating under continuous flow, allowing control over the size of the encapsulated particles which are spheroidal in shape with diameters ranging from 50 to nm. This microfluidic platform simplifies the processing procedure of water-in-oil-in-water (w/o/w) encapsulation, as now a time and cost saving one-step process devoid of any organic solvents, in contrast to the conventional homogenization process which is inherently complex, involving multiple-steps and the use of organic solvents. Moreover, use of homogenization (as a benchmark to encapsulate fish oil) afforded much larger macroparticles, ranging in size from 2 to 4 µm. Smaller encapsulated particles fabricated using VFD processing could lead to improved absorption from fish oil. Overall, VFD processing provides a new alternative bottom-up approach to easy, scalable processing, without the need for organic solvents which are counterproductive in the food industry.
