2024年4月1日 · Fe-spiking experiments demonstrate that high OER activity is achieved upon the introduction of Fe. After Fe introduction, further activity increase with cycle number correlates with the increased quantity of redox-active Ni.

2024年1月4日 · Herein, we introduced trace Fe nanosheets to construct novel Fe/reduced graphene oxide (Fe/RGO) composite absorber based on the different electron gain and loss capabilities (The work function of Fe is 4.5 eV and that of graphene is 5.0 eV) to gain insight into the regulatory effects of trace Fe on the dielectric properties of RGO.

2024年11月11日 · Trace Fe doping facilitates the construction of abundant Fe 2 P/CoP heterojunctions, effectively modulates the charge distribution at the interface, and consequently enhances the OER/HER catalytic efficiency of CoP nanoFCs.

Using off-axis electron hologram testing combined with simulation calculation and carrier transport property experiments, we demonstrate here the carrier injection behavior from Fe to graphene at the interface and the induced charge accumulation and rearrangement, resulting in the increased interfacial and dipole polarization and the ...

2021年1月15日 · The Fe tracer diffusion coefficients as a function of the Fe concentration in Fe–Ga alloys after application of the combined analysis of chemical and tracer diffusion data. Plots show the comparison of the tracer diffusion coefficients with (open symbols) and without (closed symbols), taking into account the changes in molar volume.

2023年2月17日 · This study offers an idea for synergistically improving the performance of Li-rich layered oxides by co-doping trace Fe cations and F anions simultaneously, which play a complementary role in performance improvement.

2024年1月4日 · Using off-axis electron hologram testing combined with simulation calculation and carrier transport property experiments, we demonstrate here the carrier injection behavior from Fe to graphene at the interface and the induced charge accumulation and rearrangement, resulting in the increased interfacial and dipole polarization and the ...

Iron incorporation is essential for the record activity of NiFe-(oxy)hydroxides to oxygen evolution reaction (OER), but the details of how Fe affects catalysis remain under active investigation. In this work, we present a double thin-layer strategy for finding unique and solid evidence for the role of Fe in the OER mechanism.
