2021年2月10日 · Herein, a kinetically controlled hydrolysis strategy is proposed for the scalable synthesis of γ-FeOOH nanosheets arrays (NAs) with enhanced structural stability on diverse substrates at ambient conditions.

羟基氧化铁是一种含铁无机化合物，分子式为FeOOH，分子量为88.9326。 羟基氧化铁在工业中可用于脱硫工序，可以在一定情况下可替代ZnO，其成本较ZnO更低廉，且脱硫效果更好。

FeOOH-NiFe LDH界面可以促进界面电荷转移，延缓Ni氧化并将NiFe LDH相诱导为高活性的β-Ni (Fe)OOH。 FeOOH@β-Ni (Fe)OOH 表现出优异的 OER 性能（252 mV at 100 mA cm -2) 并且相对于 NiFe LDH 的活性相 γ-Ni (Fe)OOH，转换频率 (TOF) 增加了 1.6 倍（在 300 mV 的过电势下）。 这项工作阐明了日粮界面工程可以调节 OER 过程中高活性相的产生。 界面工程是设计活性析氧电极的有效策略。 然而，由于缺乏真实活性相的直接证据，异质界面的内在机制在很大程 …

2020年10月15日 · Here, we present a detailed study of the coagulation behavior of Fe (II) salts and crystallization of flocs, and investigate the effect of humic acid (HA) under different DO concentrations and pH conditions.

3 天之前 · The gas-phase molecule was calculated in a box of 20 × 20 × 20 Å 3 using only the Gamma point. The transition states along different diffusion pathways were determined using the climbing image ...

2022年12月5日 · The FeOOH@ β-Ni(Fe)OOH reached 100 mA cm −2 at a low overpotential of 252 mV with excellent stability. This study provides direct experimental evidence for interfacial engineering of phase transition utilizing operando characterizations and also provides insight into the design of high-performance, mass-producible electrocatalysts.

2023年6月30日 · Herein, we successfully construct serious of Ni-MOFs with differing thickness ranging from 1 nm to 270 nm through a competitive coordination strategy. Utilizing the operando resonance spectroscopy, an accurate phase inversion behavior of the Ni-MOFs has been witnessed during the OER, and demonstrated as a thickness-dependent process.

Alpha, beta, gamma, and delta hydroxyl ferric oxides (FeOOH), as the most common rust layers on iron surface, play different roles in iron preservation.

2009年5月27日 · Crystalline nanotubes of gamma-AlOOH and gamma-Al(2)O(3) have been synthesized. An anionic surfactant-assisted hydrothermal process yields gamma-AlOOH nanotubes, and appropriate calcination treatment of the gamma-AlOOH nanotubes yields gamma-Al(2)O(3) nanotubes.
