Rational design and facile synthesis of highly active electrocatalysts with low cost for oxygen reduction reaction (ORR) are always of great challenge. Specifically, development of a new type of energy-saving materials with convenient method is regarded as the current bottleneck. Herein, an innovative strategy based on amino trimethylene phosphonic acid (ATMP) as chelating agent for cobalt-metaphosphate coordination polymer is reported to one-pot synthesis of a novel precursor in methanol for ORR electrocatalyst. Carbonization of the precursor at 900 °C at N 2 atmosphere results in the feasible formation of cobalt metaphosphate based composite (Co(PO 3 ) 2 /NC). A further step in the thermal cleavage at 650 °C at air for 4 h, Co(PO 3 ) 2 /NC can be finally transformed into inorganic Co(PO 3 ) 2 . Advanced spectroscopic techniques and density function theory (DFT) calculations are applied to confirm the main catalytically active center and the physical properties of Co(PO 3 ) 2 /NC. This obtained Co(PO 3 ) 2 /NC nanocomposite exhibits superior electrocatalysis to Co(PO 3 ) 2 with an enhanced onset potential (0.906 V vs. RHE) and diffusion limiting current (5.062 mA cm −2 ), which are roughly close to those of commercial 20% Pt/C (0.916 V, 5.200 mA cm −2 ).

Currently, there is a rising need for smart packaging materials that can be applied for the real-time visual monitoring of food freshness. In this work, new Co-based MOF (Co-ATMP) nanocrystals with ammonia-sensitivity function were prepared and then blended with polyvinyl alcohol (PVA) matrix to construct smart active packaging materials. The effect of Co-ATMP nanofiller upon structure, physical, and functional performances of the PVA films were then analyzed in detail. Results demonstrate that nano Co-ATMP fillers are distributed well within the PVA matrix through the formation of new hydrogen-bonding interaction, which make an obvious increase in the ductility, moisture permeability, and UV-blocking ability of the PVA film. Besides, the prepared PVA/Co-ATMP blend films present high antibacterial activity, ammonia-sensitivity as well as color stability. Ultimately, the PVA/Co-ATMP blend films were successfully employed for indicating the deterioration of shrimp through noticeable color variations. Therefore, the PVA/Co-ATMP blend films have great potential for utilization in smart active packaging area.

Although flexible supercapacitors (FSCs) have attracted tremendous attention, synthesis of supercapacitor electrodes that have outstanding electrochemical performance and excellent flexibility remains a continuous dilemma. Herein, conductive polymer composite hydrogels were synthesized via in situ polymerization of aniline (ANI) in a mixture of polyvinyl alcohol (PVA) and carbon nanotubes (CNTs), for which amino trimethylene phosphonic acid (ATMP) was employed as an organic doping acid. The as-prepared polyaniline (PANI)/PVA/ATMP/CNTs (PPAC) composite hydrogel electrodes exhibit a specific capacitance of up to 389.5 F g–1 at 0.5 A g–1, satisfactory long-term cycling stability (83.87% capacitance retained after 10,000 charge/discharge times), and outstanding flexibility (97% capacitance retained over 200 repeated bends), and the incorporation of ATMP enhanced electrochemical performances of PPAC composite hydrogel electrodes. Besides, the synergistic effects offered by high electrical conductivity of CNTs, pseudocapacitance of PANI, and the doping effect of ATMP may further contribute to the excellent electrochemical behavior of hydrogel electrodes. The result of the energy storage mechanism implied that the electrochemical process of the PPAC composite hydrogel electrode involved both diffusion-controlled and surface capacitive processes. The all-hydrogel-state FSC based on the PPAC hydrogel electrode shows a favorable energy density of 12.8 W h kg–1 at 125.0 W kg–1 as well as long-life stability of 77.31% capacitance retention after 10,000 charge/discharge cycles. This work is promising for the preparation of high-performance composite hydrogel electrodes for wearable and flexible energy storage devices.

Owing to the similar surface properties of scheelite and fluorite , the separation of them is very difficult by only using the traditional collectors of fatty acids. In this study, Nitrilotri(methylphosphonic acid) (ATMP) was used as a depressant to realize the efficient separation of these two minerals. The separation performance and the adsorption mechanism of ATMP on scheelite and fluorite were explored by the flotation experiments and surface analyses. Flotation results indicated that ATMP exhibited strong inhibition on the fluorite flotation but did not affect that of scheelite, and a satisfactory separation of scheelite from fluorite was achieved at the reagent regime of 60 mg/L ATMP, 40 mg/L sodium oleate (NaOL) and pH 10.0. Zeta potential measurements and AFM detections showed that the intense adsorption of ATMP onto fluorite was occurred and which could prevent the subsequent adsorption of NaOL on fluorite, while the adsorption of ATMP onto scheelite was weak and the further interaction between NaOL and scheelite was hardly influenced by it. Moreover, Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) analyses confirmed that the interaction between calcium ions exposed on fluorite surface and the phosphate groups of ATMP accounted for the chemisorption of ATMP on fluorite. As a result, ATMP can be selected as a potential depressant for separating scheelite from fluorite.

As a kind of advanced water purification technology, nanofiltration (NF) has been widely used in the treatment of water. In the NF process, scale inhibitor such as aminotris (methylenephosphonic acid) (ATMP, H 6 atmp, H 6 L) is commonly added to control scale deposition. However, the impact of ATMP on the separation performance of NF has up to now been unknown. In this study, the impact of ATMP on calcium ion (Ca 2+ ) rejection rate and permeate flux of NF 270 membrane were investigated by permeate experiments with different ATMP concentrations. The results showed that ATMP had a significant impact on Ca 2+ rejection rate, as well as the feed pH. Both a local minimum in rejection rate and a slight maximum in permeate flux appeared at 10 mg·L –1 ATMP, corresponding to the feed pH about 5.5, which may be close to the isoelectric point (IEP) of membrane. When ATMP concentration was below 8 mg·L –1 and above 10 mg·L –1 , increasing ATMP concentration would both dramatically enhance Ca 2+ rejection rate. The main mechanism affecting the performance of NF was electrostatic effect caused by ATMP rather than its chelation effect. Our work demonstrated that in addition to the scale inhibition effect, ATMP in water also had a certain impact on the performance of NF membrane, especially for treating low alkalinity water (contain hardness and SO 4 2- ), and aminotris (methylene phosphonic acid) (ATMP, H 6 atmp, H 6 L) is preferred to avoid precipitation and improve NF softening and desalination performance.

The effect of irradiation on actinide sorbents potentially employed in nuclear waste management, should be investigated to evaluate their feasibility in real-world applications. In this study, hafnium-amino trismethylene phosphonate (Hf-ATMP), which is a type of organic–inorganic hybrid sorbents for actinides, was exposed to 60 Co gamma rays, and the effects of ionising radiation on actinide sorption performance and its microstructure were investigated. Thereafter, the irradiation effect on other materials of this type was studied. The results revealed that the actinide sorption performance of Hf-ATMP was significantly enhanced by irradiation; the saturated Th(IV) sorption capacity of Hf-ATMP increased by 58.1% after irradiation with a dose of 2.4 MGy. The selectivity for actinides and the sorption performance for trace amounts of radioactive 239 Pu and 237 Np were also comparable to those of pristine Hf-ATMP. The structural characterisation of Hf-ATMP before and after irradiation indicated that the P-O–H groups in Hf-ATMP were converted into P-O-Hf groups upon irradiation. The pore volume and BET surface area of Hf-ATMP decreased, but the bulk chemical structure of Hf-ATMP was not damaged by gamma irradiation. Additionally, the enhancement of actinide sorption performance by gamma irradiation was observed with several other metal phosphonates. The results indicated the application potential of metal phosphonates as actinide sorbents in practical nuclear processes. Besides, this study opens a new door for improving the sorption performance of metal phosphonate sorbents using irradiation techniques.

The high flammability and severe melt-dripping during the combustion are the most marked fire hazards for polyesters, such as polylactic acid (PLA). In this work, a bio-based flame retardant (ATMP-NA-Fe) was successfully synthesized by a simple aqueous ionic reaction by using amino trimethylene phosphonic acid (ATMP), nicotinamide (NA) and FeCl 3 •6H 2 O as raw materials. The ATMP-NA-Fe and ammonium polyphosphate (APP) have good synergistic effects on improving the flame-retardant performance and retarding the combustion melt-dripping of PLA. With a 10 wt% total loading of ATMP-NA-Fe and APP (1:1), the limiting oxygen index value of corresponding PLA composite (PLA3) increases from 20.1% to 32.8%, and it passes UL-94 V-0 rating without melt dripping. The cone calorimetry results show that compared with pure PLA, the peak heat release rate, total heat release and average mass loss rate of PLA3 are reduced by 66.4%, 14.9% and 76.7%, respectively. Via the analysis on the condensed and gas phase products, the flame-retardant mechanism of PLA/APP/ATMP-NA-Fe composites is proposed. This work provides a new approach for improving flame-retardant performance of PLA and promoting the utilization of renewable resource.

High electronic conductivity and excellent specific capacitance still remain challenge for the practical application of hydrogel electrodes. Herein, a novel polymer composite hydrogel electrode, PANI/PVA/ATMP/Ag (PPA-Ag), has been successfully constructed through in situ polymerization of aniline (ANI) in solution of polyvinyl alcohol (PVA), amino trimethylene phosphonic acid (ATMP) and silver nitrate (AgNO3). The incorporation of AgNO3 is expected to enhance the electronic conductivity and excellent specific capacitance of PPA hydrogel electrodes. The AgNO3 incorporated PPA-Ag hydrogel electrode exhibited a superior specific capacitance (510 F g-1 at 0.5 A g-1), which was much higher than the pristine one without introducing AgNO3 (317 F g-1 at 0.5 A g-1). Additionally, the PPA-Ag hydrogel electrode also showed excellent flexibility (93.43% capacitance retention after 200 cycles of bending) and excellent cyclic stability (81.41 % of initial capacitance after 10000 cycles). The energy storage mechanism originated from the three-dimensional porous structure of hydrogel, the multiple redox structures of polyaniline and the Ag+/Ag of silver nitrate. The all-hydrogel-state supercapacitor was assembled based on the PPA-Ag hydrogel electrode, which delivered a high energy density of 13.3 W h kg-1 at a power density of 125 W kg-1. Meanwhile, the supercapacitors can also maintain above 77% of the initial capacitance after 10000 charge-discharge cycles. This work constructed polymer hydrogel electrodes with high electronic conductivity and excellent specific capacitance for flexible supercapacitors, which demonstrated the great potential within the field of flexible energy storage.

Nickel electroplating is a critical surface treatment technology that provides essential corrosion protection and ensures high electrical conductivity, both vital for maintaining the structural integrity and operational safety of modern metal components. However, inherent micropores within the plated layer can compromise its protective function and accelerate substrate corrosion. In this study, we present a novel, environmentally friendly, chromium-free sealing strategy based on an aminotrimethylene phosphonic acid (ATMP)-Zn²⁺ system, synergistically enhanced with benzotriazole (BTA). The specially formulated sealing bath selectively reacts with substrate exposed at pore bottoms while remaining inert to the sound nickel surface, allowing targeted pore filling through strong –PO(OH)₂–metal interactions. The resulting coating significantly reduces porosity (from 13.3 ± 1.6 cm⁻² to 1.7 ± 0.9 cm⁻²), maintains excellent electrical conductivity, and endures 2 h of neutral salt spray without corrosion. XPS and FTIR analyses confirm BTA’s synergistic role via N-H⁺···⁻O-P bonds and the optimized P-O-M coordination. This environmentally friendly approach offers a high-performance sealing solution that preserves the functional properties of Ni electroplating layers.

Amino trimethylposphonate(ATMP) functionalized HAP were synthesized with different ATMP addition (0, 5%, 10%, 15%) and the adsorption performance towards Pb 2+ and Cd 2+ were studied in an aqueous solution. Under the optimum condition, HAP with ATMP addition of 10% (10AT-HAP) displayed the most efficient adsorption performance with the adsorption capacity of 1458.79 mg/g and 321.26 mg/g towards Pb 2+ and Cd 2+ , respectively, which improved 76% and 92% than that of the artificially prepared HAP in the laboratory, respectively. For both heavy metal ions , the adsorption mechanism also included ion exchange and surface complexation, in which the surface complexation played a predominant role. In addition, XRD showed that a new crystal phase was formed after Pb 2+ adsorption, while no new phase appeared after Cd 2+ adsorption, indicating that the adsorption mechanism of Pb 2+ involved dissolution-precipitation. The fitting results of adsorption isotherm and kinetics showed that the adsorption of Pb 2+ and Cd 2+ on HAP and 10AT-HAP were well fitted by the Langmuir isotherm model and Pseudo-second model. Moreover, Multiwfn wavefunction program based on density functional theory (DFT) was applied to deeply probe and vividly visualize the interaction sites, interaction types, interaction strength and the essence of interactions between HAP and ATMP or ATMP-HAP composite and heavy metal ions.

Due to the complexity of the synthetic process of cobalt phosphides (CoP), ongoing efforts concentrate on simplifying the preparation process of CoP. In this work, amino tris(methylene phosphonic acid) (ATMP, L1) and melamine (MA, L2) are assembled into two-dimensional (2D) organic nanostructures by hydrogen bonding and ionic interactions via a supramolecular assembly, which greatly weakens the coordination ability of L1 with Co2+. As the introduced L2 is rich in carbon and nitrogen, it allows the cobalt–organophosphate complex to be placed under a strongly reducing atmosphere during the high-temperature calcination process to achieve an in situ phosphating purpose. The resulting catalyst (N-CoP/NC) exhibits the sought-after enhanced oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) performance. For the ORR in 0.1 M KOH, an enhanced onset potential (0.908 V vs. RHE) and diffusion limiting current (6.280 mA cm−2) can be obtained, which is comparable to those of 20% Pt/C (0.911 V vs. RHE, 5.380 mA cm−2). For the HER in 0.5 M H2SO4, an overpotential of 150 mV is required to drive a current of 10 mA cm−2. Moreover, Density Functional Theory (DFT) calculations reveal the catalytic pathway of N-CoP/NC.

The extensive evaporation-induced aggregation of scale inhibitors in the wastewater of recirculating cooling systems causes severe environmental pollution . In this study, Amino Trimethylene Phosphonic Acid (ATMP), an ordinary scale inhibitor, was degraded via electrochemical oxidation using a multi-layered Ti/IrO 2 -RhO x -TiO 2 /α-PbO 2 /β-PbO 2 electrode. The electrochemical oxidation experimental results verified the superior electro-catalytic properties of the β-PbO 2 electrode. Accelerated lifetime tests suggested that Ti/IrO 2 -RhO x -TiO 2 /α-PbO 2 /β-PbO 2 possesses a service lifetime of 201 h under a current density of 40000 A/m 2 , which is 3.4–100.5 times as long as other β-PbO 2 electrodes reported by other researchers. Four major operational parameters, namely electrolyte, current density, initial ATMP concentration, and pH, were discovered to significantly affect the ATMP degradation rate and electrical efficiency. The direct oxidation mechanism predominated in the degradation process of ATMP, achieving a 55.11% and 38.82% removal efficiency in Na 2 SO 4 and NaCl solutions, respectively. In addition, two possible degradation pathways of ATMP were proposed: induced by the breaking of either C-P or C-N bonds.
