2018年8月1日 · Optical, electronic and catalytic properties of transition-metal-doped α-Fe 2 O 3 (TM-doped α-Fe 2 O 3) have been systematically investigated. Cobalt has been identified as the best dopant for α-Fe 2 O 3, reducing the OER overpotential by 0.16 V with respect to the undoped. 1. Introduction.

2024年6月5日 · Herein, we show that Fe2 O 3 -modulated P-doped CoMoO 4 on nickel foam (Fe-P-CMO) is an excellent bifunctional HER/OER electrocatalyst in alkaline media, with the adverse effect of phosphorization on the OER activity of CoMoO 4 being countered via Fe 2 …

2021年4月16日 · All of the doped M-Fe 2 O 3 exhibited enhanced catalytic activity compared to the pristine Fe 2 O 3, owing to the synergistic effect of the doped metal together with Fe. Among all of the as-prepared catalysts, Ni-Fe 2 O 3 showed outstanding stability and OER activity due to the higher electronegativity of Ni compared to that of Mn or Co.

2023年7月10日 · In this study, three-dimensional (3D) titanium microfiber felt (Ti felt) was used as a conductive substrate to prepare a Ti-doped Fe 2 O 3 photoanode via a hydrothermal method with a two-step annealing treatment in air and argon atmospheres.

2024年2月4日 · Porous La-doped Fe2O3 (Fe2O3-La) nanorods have been synthesized through a facile hydrothermal method and subsequent heating process. The Fe2O3-La not only showed larger surface area, higher specific ...

2023年2月10日 · In this study, cobalt (Co) was selectively doped into the bottom and/or top layers of double-layered α-Fe2O3 nanorod arrays grown on conductive transparent substrates (F:SnO2, FTO) via a two-step hydrothermal method; this process was performed to enhance the charge transfer ability and thus significantly improve the PEC performance.

2019年4月11日 · The Fe 2 O 3 nanoparticles modified 2D N-doped porous graphene-like carbon material (Fe (1.0)–N/C-800) was fabricated from the one-step pyrolysis of low-cost and abundant substrates (β-cyclodextrin, urea and iron trichloride hexahydrate) for …

This research utilized easily recoverable superparamagnetic γ-Fe 2 O 3 nanoparticles as a reusable catalyst for PET glycolysis. γ-Fe 2 O 3 nanoparticles were produced by calcining Fe 3 O 4 nanoparticles prepared by the co-precipitation method.
