Pt/α-Fe2O3 nanocomposites were synthesized on fluorine-doped tin oxide (FTO) substrates by a sequential plasma enhanced-chemical vapor deposition (PE-CVD)/radio frequency (RF) sputtering approach, tailoring the overall Pt content as a function of sputtering time. The chemico-physical properties of the as-prepared systems were extensively investigated by means of complementary techniques, includ...
α-Fe2O3 nanomaterials with an elongated nanorod morphology exhibiting superior electrochemical performance were obtained through hydrothermal synthesis assisted by diamine derivatives as shape-controlling agents (SCAs) for application as anodes in lithium-ion batteries (LIBs). The physicochemical characteristics were investigated via XRD and FESEM, revealing well-crystallized α-Fe2O3 with adjus...
A novel modified ion selective electrode based on Fe2O3-clorprenaline/tetraphenylborate nanospheres (Fe2O3-CLPT NSs) as electroactive materials for the determination of clorprenaline hydrochloride (CLP) is described. The α-Fe2O3 nanoparticles (NPs) were prepared by hydrothermal synthesis, then self-assembled on CLP/tetraphenylborate (TPB) to form Fe2O3-CLPT NSs, which were used as a potentiomet...
Depositing a cocatalyst has proven to be an important strategy for improving the photoelectrochemical (PEC) water-splitting efficiency of photoanodes. In this study, Ni(OH)2 quantum dots (Ni(OH)2 QDs) were deposited in situ onto α-Fe2O3 photoanode via chelation-mediated hydrolysis method. The photocurrent density QDs/α-Fe2O3 reached 1.93 mA(cm−2 at 1.23 V vs. RHE, which is 3.5 times that α-Fe2O...
The poor internal quantum efficiency (IQE) arising from high recombination and insufficient absorption is one of the critical challenges toward achieving high efficiency water splitting in hematite (α-Fe2O3) photoelectrodes. By combining the nanowire (NW) geometry with the localized surface plasmon resonance (LSPR) in semiconductor-metal-metal oxide core-multishell (CMS) NWs, we theoretically d...
Hematite (α-Fe2O3) is recognized as a promising photoelectrode material for photoelectrochemical (PEC) water splitting, result of its abundance, non-toxicity, suitable bandgap, and photochemical stability. Nevertheless, the undesirable physical photophysical behaviors, such poor conductivity, short diffusion length, rapid charge-carrier recombination, seriously restrict PEC splitting efficiency...
