The formation of phytic acid decorated waste paper-derived hydrothermal carbon (WPC-P) were achieved. • The introduction of phytic acid enables to improve the oxygen-containing groups and specific surface area of WPC-P. • The phytic acid modified WPC-P exhibited upgraded adsorption activity of Cr(VI). • The mechanism of Cr(VI) removal was generated by electrostatic, chelation, and reduction interactions. Biomass-derived hydrothermal carbon has garnered considerable interest as a promising approach for heavy metal wastewater treatment. In this study, hydrothermal carbon derived from waste paper and coupled with phytic acid (WPC-P) was synthesized via a one-step hydrothermal process as an effective adsorbent for Cr(VI) removal. Characterization results indicated that P and O were dispersed uniformly on the surface of WPC-P. The introduction of phytic acid could greatly increase the specific surface area and number of active functional groups. The results of adsorption tests indicated that WPC-P exhibited highly efficient removal performance for Cr(VI) with maximum uptake of 174.05 mg·g −1 . The adsorption capacity of WPC-P was 10 times higher than that of WPC at 2 h. Analysis of the experimental data using adsorption kinetic and isotherm models revealed that the adsorption process of WPC-P fitted both the pseudo-second-order kinetic model and the Langmuir adsorption isotherm model well. After five consecutive adsorption-desorption cycles, the WPC-P retained about 87% of its initial capacity. The enhanced adsorption performance, ascribed to the introduction of phytic acid, could be attributed to the complexation, electrostatic interactions and reduction reactions induced by active functional groups on WPC-P. This work reported a simple method to prepare carbon adsorbents from biomass waste, which showed great potential for treating chromium-containing wastewater.

Liquid metal (LM)-based conductive hydrogels have attracted considerable attention in wearable technology due to their superior electrical conductivity and excellent biocompatibility. However, developing LM composite hydrogels that simultaneously achieve high sensitivity, long-term durability, and superior mechanical properties remains a challenge for meeting the demands of advanced wearable applications. In this study, we introduce phytic acid (PA), a naturally occurring small molecule, whose unique interfacial stabilization properties arise from the dual functionality of its phosphate groups: (i) the ability to form strong coordination bonds with metal surfaces, and (ii) the enhancement of the polymer network through multiple hydrogen bonds and electrostatic interactions, significantly improving the dispersion stability of LM within the hydrogel matrix. Based on this strategy, we successfully fabricated PLM x hydrogels with superior electrical conductivity (∼0.53 S m −1 ), exceptional toughness (∼9.7 MJ m −3 ), and remarkable durability (>11,000 cycles). The PLM x hydrogel exhibits outstanding sensitivity (gauge factor ∼8.1) and enables wireless dual-mode signal detection—precisely monitoring vigorous human motion and sensitively detecting subtle physiological signals. Notably, even under prolonged use and high-frequency cycling conditions, the PLM x hydrogel maintains excellent signal responsiveness and operational stability, demonstrating its tremendous potential for applications in smart health monitoring, human-machine interfaces, and next-generation wearable devices.

Phytic acid-stabilized Fe 3 O 4 -graphene oxide (GOPA@Fe 3 O 4 ) was assembled by microwave-enhanced hydrothermal synthesis and super-amphipathicity was demonstrated by measurement of dynamic oil and water contact angles. GOPA@Fe 3 O 4 was used as a sorbent for enrichment of eight polycyclic aromatic hydrocarbons (PAHs) from vegetable oils by magnetic solid-phase extraction (MSPE). The extraction-desorption factors were systematically investigated and, under optimum conditions, the super-amphiphilic sorbent achieved wide linear ranges (0.2–200 ng g −1 ), satisfactory precision (3.44–6.64% for intra-day and 5.39–8.41% for inter-day) and low limits of detection (LODs, 0.06–0.15 ng g −1 ) for PAHs. Excellent recoveries (85.6–102.3%) for spiked PAHs were obtained with genuine vegetable oil samples. These results indicate that MSPE using GOPA@Fe 3 O 4 as the sorbent, coupled with high performance liquid chromatography (HPLC), is an efficient and simple method for the detection of low concentrations of PAHs in vegetable oils.

To address the challenge of uranium-contaminated wastewater, flow-electrode capacitive deionization (FCDI) has emerged as a promising technology owing to its advantages of electric field enrichment and electrode recyclability. In this study, porous carbon spheres were synthesized from aniline via a hard-template carbonization method and subsequently functionalized with phytic acid to obtain phytic acid-doped porous carbon spheres (PAPCS) as a novel flow-electrode material. Under optimized conditions, PAPCS displayed a specific activity of 13.95 μL·cm −2 ·s −1 , which is much higher than reported in previous studies. Further, only 4 h was required to reduce uranium concentration in wastewater from 0.1 mg L −1 to 25.2 μg L −1 . Thus, the uranium concentration in the treated wastewater reached the national drinking water standard (<30 μg L −1 ). At higher initial concentrations (1.0, 5.0, and 30.0 mg L −1 ), the removal efficiencies reached 88.29 %, 92.7 %, and 95.57 %, respectively. After nine adsorption cycles, the material retained over 80 % of its initial capacity, showing that its stability and reusability remain reasonably high. Density functional theory (DFT) calculations further revealed that the adsorption energies of porous carbon spheres toward uranyl ions decreased significantly decreased from −2.9556 eV to −3.5095 eV after phytic acid functionalization, confirming that phytic acid substantially enhance the adsorption capacity. These results highlight that the integration of phytic acid-functionalized porous carbon with FCDI technology provides an efficient, stable, recyclable, and environmentally friendly approach for uranium wastewater treatment, offering enormous potential for practical applications.

Synergistic effect of rare earth salts conversion coating with phytic acid conversion coating was studied. Rare-earth salts were used as post-treatment to modify the phytic acid coated steel. The corrosion resistance properties of different coatings was investigated with electrochemical impedance spectroscopy in 3.5 wt.% NaCl solution. The corrosion resistance of phytic acid coated steel on steel was further enhanced with cerium nitrate post-treatment. The corrosion rate of phytic acid coated steel was seriously impaired by cerium nitrate post-treatment. But scanning electron microscopy (SEM) images indicated that there are also some micro-cracks on the coating surface when phytic acid coated steel was post-treated with cerium nitrate conversion bath. X-ray photoelectron spectroscopy (XPS) results demonstrated that the phytic acid could bind to the steel surface through the formation of -P-O-Fe and the cerium salts on the steel surface existed in the forms of both Ce 3+ and Ce 4+ .

Achieving superlubrication on engineered steel surfaces is critical to reduce friction and wear in mechanical engineering. Herein, a lubricant with rapid superlubrication properties is designed by phytic acid (PA) modified black phosphorus (BP) nanosheets (PA-BP) into a mixture of poly (aspartic acid) (PASP) and ethylene glycol (EG) solution (PASP/EG). It is able to achieve a superlubrication state ( µ ≈ 0.0048) at a high contact pressure of 710 MPa on the engineered steel surface and the time to reach superlubrication (tRs) is only 26 s. The addition of PA-BP could reduce wear rate by 96% on the steel surface (1.51×10 −10 mm 3 N −1 m −1 ) compared to the lubrication of PASP/EG. The surface analysis and molecular dynamics simulations show that PA-BP nanosheets are easily adsorbed on the steel surface to form an adsorbent tribofilm. These PA-BP nanosheets occur oxidation during the friction process, which could adsorb water molecules in PASP/EG to form a water layer with a thickness of 18 Å. This leads to the transformation of the shear interface into water layer with low shear strength, thus achieving the rapid superlubrication at high contact pressure. This work provides a new idea for the design of rapid macroscopic superlubrication on engineered steel surfaces for industrial applications.

Conventional epoxy coatings rely primarily on passive barrier effects and therefore lack the ability to regulate interfacial corrosion processes after local damage. Here, a physicochemically regulated active/passive epoxy coating is developed by incorporating a phytic acid–loaded cerium-based metal–organic framework (CeMOF-P) as a functional colloidal additive. Owing to the confinement and coordination effects of the CeMOF framework, phytic acid is stably immobilized and uniformly dispersed, resulting in improved coating compactness and interfacial adhesion. Electrochemical impedance spectroscopy shows that the CeMOF-P–modified coating exhibits markedly enhanced corrosion resistance and, more importantly, a characteristic non-monotonic impedance evolution with pronounced impedance recovery upon damage, indicating an interfacial regulation mechanism beyond passive shielding. Mechanistic analyses reveal that corrosion-triggered, coordinated release of Ce 3+ /Ce 4+ species and phytic acid leads to the in situ formation of a compact cerium–phosphate–rich interfacial film, which simultaneously suppresses anodic dissolution and cathodic reactions. These results demonstrate that Ce–P synergy enables continuous interfacial regulation rather than transient passivation, providing mechanistic insight into the role of coordination chemistry and colloidal confinement in governing interfacial electrochemical behavior and stability in protective coating systems.

Wheat dust poses a significant hazard to grain processing safety due to its high explosion sensitivity. To develop an inhibitor combining high-efficiency explosion suppression with environmentally friendly and edible properties, this study innovatively employed an aqueous phase condensation-freeze-drying method to successfully synthesize a phytic acid-adenine complex (PA-A) using naturally edible phytic acid (PA) and adenine as raw materials. Characterization analyses employing laser particle size analyzer, field-emission scanning electron microscopy with energy-dispersive X-ray spectroscopy (FE-SEM/EDS) confirmed the formation of a lamellar microstructure with highly dispersed phosphorus elements. The suppression effect of PA-A on a 300 g/m 3 wheat dust explosion was systematically investigated evaluated in a vertical tube combustion apparatus (1000 × 80 × 80 mm). Results demonstrated that increasing inhibitor concentration (0 vol%-12.5 vol%) progressively suppressed flame propagation, evidenced by color transition from bright yellow to dark red, morphological fragmentation, and discontinuity. Quantitative analysis revealed peak flame propagation velocity decreased from 27.6 m/s to 10.9 m/s (a reduction of 60.5 %), maximum temperature declined from 993 °C to 367 °C (a reduction of 63.1 %), and the maximum explosion pressure attenuated from 48.3 kPa to 20.1 kPa (a reduction of 59 %), with a significant delay (>80 %) in the time to reach these peak parameters. Comprehensive analysis based on Thermogravimetry-Differential Scanning Calorimetry (TG-DSC), X-ray Photoelectron Spectroscopy (XPS), and Fourier Transform Infrared Spectroscopy (FTIR) elucidated a multi-level synergistic suppression mechanism involving endothermic cooling, gas-phase dilution, surface isolation, and free radical quenching. This study provides a safe, environmentally friendly, and edible new strategy for controlling grain dust explosions.

This research work reported a novel approach to develop flame retardant silk fabric using naturally occurring phytic acid (PA) rich in phosphorus and TiO 2 nanoparticles through a pad-dry-cure technique. A polycarboxylic acid [1,2,3,4–butanetetracarboxylic acid (BTCA)] was employed to stabilize and improve the adhesion of TiO 2 on silk surface. The flame retardancy of the treated silk fabric was determined in terms of limiting oxygen index, vertical burning, and pyrolysis combustion flow calorimetry, and the durability of flame retardancy to washing was discussed. PA and TiO 2 were found to have a joint flame retardant effect. The combination of PA, TiO 2 and BTCA was able to endow silk fabric with excellent flame retardancy, and the good flame retardant ability was kept even after 25 times of washing. The reasons for the good washing durability of the treated silk fabric were discussed. Finally, a significant condensed-phase flame retardant mechanism of the silk fabric treated with the PA/TiO 2 /BTCA system was revealed by the analyses of thermogravimetry and pyrolysis combustion flow calorimetry.

The aviation industry needs to develop sustainable, fire-safe cabin interior materials. Although wood is eco-friendly, its high flammability makes it challenging to meet flame retardant standards. Enhancing wood fire safety requires the creation of an environmentally friendly and flame retardant coating. In this study, a new type of intumescent flame retardant (IFR) coating was applied to the wood surface using the layer-by-layer (LBL) technique, with fully bio-based chitosan (CS), agar, and phytic acid (PA) as key components. The coated wood demonstrated improved durability, flame resistance, and thermal stability. Particularly, the Wood-2 sample achieved a vertical burning test (UL-94) V-0 rate and a limiting oxygen index (LOI) of 53.1%, which exceeded most previous reported flame retardant coatings. Cone calorimeter test and infrared thermography analysis confirmed that a thick layer of intumescent char formed when the coating was exposed to heat, effectively hindering heat transfer and oxygen supply. This flame retardant effect is attributed to a synergistic mechanism involving nitrogen/phosphorus (N/P) elements. This study offers an environmentally friendly solution for wood flame retardancy and lays an experimental and theoretical foundation for the development of green aviation interior materials.

High energy density, stable, and inexpensive electrode materials have the potential to improve the performance of lithium–sulfur (Li–S) batteries. Developing high porosity, high conductivity, and a network framework for multidirectional ion transfer in Li–S batteries, on the other hand, remains a significant challenge. Nitrogen and phosphorus co-doped porous carbon sheets (PCS900) are designed and synthesized here with high porosity and abundant active sites. PCS900 can withstand high sulphur loading while also providing multidirectional ion transport channels. Density functional theory (DFT) calculations indicate that nitrogen and phosphorus co-dopants play an important role in suppressing the shuttle effect via the chemical interaction between sulfur and the carbon framework. At a current density of 1 C, the PCS900/S electrode has an initial specific capacity of 737 mA h g−1, and the average capacity decay rate per 500 cycles is as low as 0.079%. Furthermore, the heat released during the discharging process is greater than the heat released during the charging process due to the combination of in situ XRD and microcalorimetry techniques.

A novel and environmental-friendly pretreatment layer was prepared on a mild steel from an aqueous solution of polyvinyl alcohol (PVA)-grafted phytic acid (PA). This composite pretreatment layer provides greatly improved adhesion to the metal substrate, owing to the strong chelation and coordination interaction between PA and metals. Meanwhile, PVA modification produces highly porous structure in the hybrid layer. This is beneficial to the improvement of adhesion between metal substrates and subsequent polymer coatings. Further, the highly porous structure is good at loading -corrosion inhibitors, and the polymeric coatings painted on PVA-PA pretreatment layer pre-encapsulated with inhibitors exhibit satisfactory anticorrosion performance.
