Study about an assembly of iron(III) hexacyanoferrate(II) and α-Fe2O3 as a secondary photocell: Part 1. Synthesis, characterization and photoelectrochemical properties of FTO/α-Fe2O3/KFe[Fe(CN)6]3 electrode system

Composites of NiS2 Microblocks, MoS2 Nanosheets, and Reduced Graphene Oxide for Energy Storage and Electrochemical Detection of Bisphenol A

“…The electrochemical detection performance of the asprepared NiS 2 , MoS 2 , and NiS 2 /MoS 2 /rGO electrodes was investigated using [Fe(CN) 6 ] 3−/4− as a redox probe, which shows high electrochemical activity and a quasi-reversible behavior. 36,37 Figure 6a and Figure S9 shows the CV curves of bare GCE, NiS 2 /MoS 2 /rGO-GCE, and rGO-GCE, which is still a closed curve and indicates that the NiS 2 /MoS 2 /rGO nanocomposite has formed a dense film on the surface of GCE, as well as that of rGO. Moreover, the reduction-to-oxidation peak potential difference (ΔE p ) of bare GCE and NiS 2 /MoS 2 / rGO-GCE at 50 mV s −1 was calculated to be 98 and 81 mV, that means the electron transfer on NiS 2 /MoS 2 /rGO-GCE electrode is relatively faster.…”

Scalability and Investigation of the Geometrical Features and Shapes of a Tandem Photo-Electrolysis Cell Based on Non-Critical Raw Materials

“…The easily mass-producible and highly scalable technology of photo-electrolysis has the potential to eventually achieve cheaper hydrogen production than natural gas reforming plants, thereby positively impacting the sustainability of hydrogen production as no hydrocarbon molecules are involved in photo-electrolytic hydrogen generation. However, many recent works have investigated PECs in a liquid electrolyte, thus the separation of the produced fuel and oxidant and the scalability of these systems is difficult [29][30][31][32]. The photo-electrolysis device proposed here is designed to directly generate high-purity hydrogen output, which can be directly employed in fuel cells, allowing their effective implementation.…”
