2023年10月8日 · We report the photoelectrochemical (PEC) performance of a densely grown single crystalline hematite (α-Fe 2 O 3) nanosheet photoanode for water splitting. Unlike expensive ITO/FTO substrates, the sheets were grown on a piece of pure Fe through controlled thermal oxidation, which is a facile low cost and one-step synthesis route.

2021年8月9日 · In this work, we report that α-Fe 2 O 3 can serve as an effective heterogeneous OAT photocatalyst in PEC systems. Different transformations, which include sulfoxidation, C=C epoxidation, the...

2019年12月1日 · Low oxygen annealing can activate a significant photoelectrochemical response of α-Fe2O3 even at a low temperature of 400 °C and provide an excellent PEC performance compared with classic air anneali...

2022年4月16日 · Herein, we developed a simple hydrothermal-calcination approach to fabricate Fe 2 O 3 nanorods (NRs) doped with Ni 2+, Ca 2+, and Mg 2+, respectively, which exhibited improved PEC performance than bare Fe 2 O 3 NRs.

2021年7月1日 · The PEC studies showed that the EG-α-Fe 2 O 3 nanorods exhibited improved photocurrent density than the bare α-Fe 2 O 3. This was attributed to the greater photoactive region provided by the compact nanorod design, which resulted in proficient light absorption, fast charge transport due to the decreased hole diffusion length, and rapid charge ...

2021年2月11日 · Low photocurrent density of hematite (α-Fe 2 O 3) originating from the inherent defects usually hinders its application in photoelectrochemical (PEC) water oxidation. In this paper, the synergetic effect of increase of oxygen vacancies and in-situ constructing heterojunction by coating MOFs on the α-Fe 2 O 3 nanoarrays gives rise to the ...

2023年3月1日 · PEC performance is limited by the inevitable light loss in thin-film Fe 2 O 3. Anti-sintering of nanorods enables both complete light absorption and short charge separation distance (d sep) in the thick film.

2019年1月29日 · It is demonstrated that the designed p-Co 3 O 4 /n-Fe 2 O 3 junction exhibits superior photocurrent density, fast water oxidation kinetics, and remarkable charge injection and bulk separation efficiency (η inj and η sep), attributing to the high catalytic behavior of Co 3 O 4 for the oxygen evolution reaction as well as the induced interfacial e...
