FeOOH nanorods, as one-dimensional nanomaterials, have been widely used in many fields due to their stable properties, low cost, and easy synthesis, but their application in the field of chemiluminescence (CL) is rarely reported. In this work, FeOOH nanorods were synthesized by a simple and environmentally friendly one-pot hydrothermal method and used for the first time as a catalyst for generating strong CL with luminol without additional oxidant. Remarkably, luminol-FeOOH exhibits about 250 times stronger CL than the luminol-H2O2 system. Its CL intensity was significantly quenched by uric acid. We established a simple, rapid, sensitive, and selective CL method for the detection of uric acid with a linear range of 20–1000 nM and a detection limit of 6.3 nM (S/N = 3). In addition, we successfully applied this method to the detection of uric acid in human serum, and the standard recoveries were 95.6–106.4%.

To overcome conventional membrane challenges in eliminating natural organic matter (NOM) from natural water, we successfully integrated β -iron hydroxide oxide ( β -FeOOH) nanorods onto a PAA-PVDF blend membrane fabricated from poly(acrylic acid) (PAA) and polyvinylidene fluoride (PVDF).Contact angle assessments with various fluids confirmed the strong organic matter adsorption property of the membrane, with a dispersion component of surface energy at 26.7 mJ/m 2 for β -FeOOH@PAA-PVDF. This membrane consistently removed over 80 % of dissolved organic matter in the cross-flow filtration of water containing 50–150 ppm fulvic acid (FA) under neutral conditions. Such remarkable performance is attributed to the interactions between the Fe-OH groups and the carbonyl (2.960 eV) and phenolic (2.864 eV) groups of FA, overcoming the size sieving limits. Under acidic conditions, zeta potential tests revealed effective ferric coagulation, resulting in over 90 % FA (50 ppm) removal. We thoroughly investigated that common cations (e.g., K + and Ca 2+ ) have impacts on FA removal using β -FeOOH@PAA-PVDF. The used membranes regained nearly original fluxes after washing with trace hydrogen peroxide (H 2 O 2 ) under ultraviolet (UV) light illumination, outperforming traditional washing with sodium hypochlorite (NaClO). Electron spin resonance spectrometry elucidated the cleaning mechanism of β -FeOOH@PAA-PVDF was superoxide anion radical ( O 2 − ) and singlet oxygen ( 1 O 2 ) active species. In summary, β -FeOOH@PAA-PVDF showed a superior adsorption capacity (2200 mg/m 2 ) and efficient photocatalytic degradation towards NOM in natural water, providing an efficient cleaning technology for membrane reuse.

Developing low-cost and high-capacity anode materials is one of the momentous issues in lithium-ion batteries (LIBs). In this study, we propose a facile one-pot hydrothermal strategy to synthesize silicon-doped FeOOH@reduced graphene oxide (Si-FeOOH@rGO) composites, which integrate the advantages of hybridization and doping engineering as novel anodes for LIBs. The Si-FeOOH nanorods are uniformly grown on the conductive rGO sheets with the formation of Fe−O−C bonding at interfaces. Results demonstrate that the doping of Si can effectively suppress the aggregation of active nanoparticles, facilitate Li + diffusion, and promote the conversion reaction of FeOOH. As a result, the optimized Si-FeOOH@rGO composite manifests high reversibility (1370.5 mAh g −1 at 0.1 A g −1 over 200 cycles), outstanding rate capability (690.4 mAh g −1 at 1 A g −1 , 599.2 mAh g −1 at 2 A g −1 ) and excellent long-term cyclability (920.1 mAh g −1 at 0.5 A g −1 and 612.7 mAh g −1 at 1 A g −1 after 380 cycles). The simple fabrication strategy and superior electrochemical performance indicate that this novel Si-FeOOH@rGO composite shows a great application prospect as anode material for advanced LIBs.

Tribocatalysis is vitally important for electrochemistry, energy conservation, and water treatment. Exploring eco-friendly and low-cost tribocatalysts with high performance is crucial for practical applications. Here, the highly efficient tribocatalytic performance of FeOOH nanorods is reported. The factors related to the tribocatalytic activity such as nanorod diameter, surface area, and surface roughness are investigated, and the diameter of the FeOOH nanorods is found to have a significant effect on their tribocatalytic performance. As a result, under ultrasonic excitation, the optimized FeOOH nanorods exhibit superior tribocatalytic degradation toward rhodamine B (RhB), acid orange 7, methylene blue, methyl orange dyes, and their mixture. The RhB and mixed dyes are effectively degraded within 20 min ( k = 0.179 min −1 ) and 35 min ( k = 0.089 min −1 ), respectively, with the FeOOH nanorods showing excellent reusability. Moreover, antibiotics, such as tetracycline hydrochloride, phenol, and bisphenol A are efficiently degraded. Investigation of the catalytic mechanism reveals that the friction-generated h + as well as these yielded •OH and •O 2 − active radicals participate in the catalytic reaction. This work not only shed light on the design of high-performance tribocatalyst but also demonstrates that by harvesting mechanical energy, the FeOOH nanorods are promising materials for removing organic contaminants in wastewater.

Quantitative analysis of biologically important compounds plays extraordinary roles in diagnostic studies of human health. In this study, a versatile electrochemical sensing platform is proposed for selective quantification of ascorbic acid (AA), dopamine (DA), uric acid (UA), acetaminophen (AC) and l -tryptophan (Trp). Such a platform is based on a nanocomposite of FeOOH nanorod and expanded graphite (FeOOH nanorod/EG), prepared through a hydrothermal process. The characterization of its morphology and electrochemical properties by means of microscopic methods and electrochemical techniques reveals that this nanocomposite exhibits outstanding electrocatalytic activity and sensing performance toward these bioanalytes. A combined action between EG and FeOOH is confirmed, where the former provides a huge electroactive surface area as well as a fast electron transfer rate, while the latter features strong electrical catalytic ability. This platform exhibits high sensitivity toward voltammetric quantitation of AA, DA, UA, AC and Trp, and their detection limits are 3.28, 0.22, 0.02, 0.0014 and 0.03 μM (S/N = 3), respectively. Beyond that, the proposed FeOOH nanorod/EG electrochemical sensing platform shows good selectivity, high reproducibility and stability in the quantitative analysis of these bioanalytes. The established sensing platform has been also successfully adopted in analyzing these bioanalytes in real biological serum and urine samples or commercial drugs. Consequently, the fabricated FeOOH nanorod/EG nanocomposite is a promising electrode material in the applications of sensing different bioanalytes.

High-performance microwave absorbers are mainly based on reasonable microstructural designs and composition regulation. Herein, a broadband microwave absorber was obtained by a two-step hydrothermal method. Notably, the transformation of MnO2 nanosheets to α-FeOOH nanorods was successfully realized on carbon aerogel powder, and the microwave absorption effect of the absorber can be adjusted in three-band absorption (S, X, and Ku bands) by changing the thickness of the absorber. The results show that the minimum reflection loss (RLmin) of the α-FeOOH/CA composite is −38 dB at a frequency of 13.28 GHz, and the corresponding effective absorption bandwidth of less than −10 dB could completely cover the Ku band. This study provides a new idea for designing carbon aerogel powder microwave absorbers reasonably and for adjusting impedance effectively.

The advanced oxidation process of the photo-Fenton reaction can produce hydroxyl radicals with extremely strong oxidizing properties for the efficient and green degradation of various chemical and microbial pollutants. Herein, we report an approach to fabricating heterogeneous Fenton catalysts of β-FeOOH nanorods on porous substrates triggered by mussel-inspired coatings of levodopa (3,4-dihydroxy-phenyl-l-alanine, l-DOPA) and polyethylenimine (PEI) for efficient photocatalytic dyes’ degradation and sterilization. The l-DOPA-based coatings not only promote the formation and immobilization of β-FeOOH nanorods on the porous substrates by strong coordination between catechol/carboxyl groups and Fe3+ but also improve the energy band structure of the Fenton catalysts through a valence band blue shift and band gap narrowing. The photo-Fenton catalysts prepared by the l-DOPA-based coatings exhibit high electron transport efficiency and improved utilization of sunlight. Only 2 h of mineralization is needed to fabricate these catalysts with excellent photocatalytic efficiency, in which the degradation efficiency of methylene blue can reach 99% within 30 min, whereas the sterilization efficiency of E. coli/S. aureus can reach 93%/94% within 20 min of the photo-Fenton reaction. Additionally, the prepared catalysts reveal a high photodegradation performance for various dyes including methylene blue, methyl blue, methyl orange, direct yellow, and rhodamine B. Furthermore, the catalysts retain high dye degradation efficiencies of above 90% after five photodegradation cycles, indicating cycling performance and good stability.

Carbon nanotube (CNT) membranes with nano-enhanced superwettability show great potential in high-efficient oil/water separation. In this study, we present a novel polyphenol-metal manipulated nanohybridization strategy to prepare CNT nanohybrid membranes embedded with FeOOH nanorods (NRs). The polyphenol-metal manipulated nanohybridization strategy lies in the assembly of polyphenol-metal (chitosan/tannic acid-Fe 3+ ) complex primer on the CNT membranes followed by in situ FeOOH NRs mineralizating. The polyphenol-metal complex modulates the uniform distribution of in situ mineralized FeOOH NRs in the as-prepared CNT@CS/TA-FeOOH nanohybrid membrane, which endows the CNT nanohybrid membrane with both superhydrophilicity and underwater superoleophobicity. By integrating the high permeability of CNT membranes and the hydrophilicity and photo-degradation activity of FeOOH NRs, the CNT@CS/TA-FeOOH nanohybrid membrane possesses achieved a high water permeability above 8000 Lm -2 h -1 bar -1 and greatly elevated flux recovery ratio above 97% for oil/water separation. Both hydration-induced antifouling property and photo-induced self-cleaning capability contributed to the robust flux recovery for highly efficient oil/water separation. The CNT@CS/TA-FeOOH nanohybrid membrane is promising for oily wastewater treatment applications, and the proposed polyphenol-metal manipulated nanohybridization strategy shows great potential for engineering various multifunctional nanohybrid membranes.

The self-assembled synthesis of a hierarchical graphene oxide (GO)-carbon nanotubes (CNTs)-α-FeOOH decorated composite aerogel (α-FeOOH@GCA) through a facile in-situ hydrolysis route is reported for the first time and the materials was tested for its performance as Fenton-like catalyst. The introduction of GO-CNTs clearly mediated the morphology to aligned α-FeOOH nanorods ( ca. 100 nm) within aerogel matrix comparing with pristine urchin-like α-FeOOH three-dimensional microstructures ( ca. 1 μm). This three dimensional porous aerogel network provided efficient charge/mass-transfer leading to great enhancement of the catalytic activity of α-FeOOH. The outstanding catalytic performance of this composite in degradation of organics with different charge and structure, i.e. Orange II (OII), rhodamine B (RhB), methylene blue (MB), phenol and endocrine disruptor bisphenol A (BPA) was demonstrated. For example, the discoloration of OII with pseudo first-order rate constant of 0.10 min −1 significantly exceeded that of pristine α-FeOOH. At relatively low concentration of α-FeOOH@GCA catalyst (125 mg L −1 ) and H 2 O 2 (0.55 mM) showed excellent catalytic activity for efficient (∼99%) discoloration of OII (40 mg L −1 ) under a 60 min UV 365 irradiation in the pH range 3–10. The different charge of five target contaminats greatly determined the surface-catalyzed degradation kinetics at natural solution pH in the order of cationic > neutral > anionic organics due to the negatively charged carbon-based aerogel matrix. The new identified desulfonation intermediates elucidated through UPLC–MS analysis indicated two reaction pathways: 1) hydroxylation and 2) desulfonation by-products followed by cleavage of the azo bond as the predominant degradation pathway of OII. The elimination of the acute toxicity of the parent contaminant to luminescent bacterium Q67 was consistent with the formation of less toxic degradation by-products identified. Free radical quenching studies accessed the role of hydroxyl radical ( OH), superoxide anion radical (O 2 − ) and singlet oxygen ( 1 O 2 ) as the dominating reactive oxygen species (ROS). The quantitative studies to measure radical concentrations using relative molecular probes showed the effective activation of H 2 O 2 led to high rate production of ROS accounted for OII degradation. The greatly enhanced photocatalytic property of this hybrid was correlated with the efficient conversion between Fe 2+ /Fe 3+ and synergistic coupling between α-FeOOH and carbon-based aerogel matrix evidenced through the formation of Fe O C chemical bonds was verified by X-ray photoelectron (XPS) analysis. Based on its simple and scalable preparation route as well as its excellent UV 365 or visible light-responsive catalytic performance, this hybrid exhibits a high potential to be used as an efficient and environmental-friendly catalyst for water remediation.

Nowadays, photo reversible color switching systems (PCSS) are always limited by some requirements, such as good stability, low toxicity, fast light response, long cycling performance and low production cost, therefore, it is a huge challenge to develop such a system that integrates beneficial features. Herein, a new type of PCSS have been demonstrated, which integrated reducing agent of triethanolamine (TEOA), catalyst of β-FeOOH nanorods and the redox driven color conversion characteristics of redox dyes. The system has the advantages of high switching rate, high reversibility (>10 cycles), wavelength selective response, safety and less light damage, which can be widely used in rewritable paper. As-prepared rewritable paper has high contrast, high resolution, suitable printing time and good reversibility, which is in line with the environmental protection concept of green printing. Rewritable paper is a kind of self-erasable rewritable medium which is highly suitable for printing. Environmental protection film has the advantages of low cost, convenient preparation and recycling. It is expected to replace the traditional writing, printing paper, existing systems and make a big step forward to practical application. Even more surprising, it also can be applied for a data encoding and reading strategy.

The photo-Fenton reaction has been widely applied in the decontamination of organic pollutants and has shown great potential in environmental remediation. The development of an appropriate catalyst with high activity and stability is essential for its success. Therefore, a composite catalyst was synthesized by in-situ mineralization of β-FeOOH nanorods on carbonized cellulose fabric (CCF) coated with polydopamine (PDA), which was denoted as β-FeOOH/PDA/CCF. The β-FeOOH/PDA/CCF catalyst with more than 77% degradation efficiency towards various contaminants and exhibited excellent chemical stability after six consecutive adsorption/degradation cycles. Radical scavenger experiments and electron paramagnetic resonance spectroscopy confirmed the presence of hydroxyl radicals (∙OH) that play a crucial role in the photo-Fenton degradation process. In addition, the degradation mechanism and pathway of MB was inferred. This work provides new perspectives on developing catalysts that demonstrate high stability and accelerated electron transfer, which can enhance the application of the photo-Fenton process in practical wastewater purification.
