A novel one-pot ultrasonic-assisted method was developed to fabricate Super P carbon black (SPCB)-bridged conductive networks comprising halloysite nanotubes (Hal) and whisker carbon nanotubes (WCN). This WCN/SPCB/Hal nanocomposite was engineered into a sensing platform on glassy carbon electrode (GCE) for diuron (DU) detection. In this architecture, the non-entangled WCN backbone offered high electrolyte adsorption capacity, facilitating the rapid ion transport. Hal provided high-affinity sites to preconcentrate DU at the interface, while SPCB bridged the conductive pathways between WCN and Hal. The resulting WCN/SPCB/Hal/GCE sensor demonstrated good electrochemical performance for DU detection with detection limit of 29.45 nM and sensitivity of 1.6121 μA/μM (linear range: 0.1–20 μM). It also demonstrated good reproducibility, repeatability, and anti-interference capability. The practical application of WCN/SPCB/Hal/GCE in juice samples yielded favorable recoveries of 95.18–102.70% and low relative standard deviations ranging from 2.30% to 4.30%, confirming its potential for rapid DU analysis in fruit-based matrices.

Diabetic wounds frequently develop infections and impaired healing due to the hyperglycemic microenvironment, creating a need for dressings with combined antibacterial and tissue-regenerative functions. Here, the lumens of halloysite nanotubes (HNTs) were employed for confined in-situ synthesis of silver nanoparticles (Ag@HNTs), which were then incorporated into a chitosan matrix by solution mixing and freeze-drying to produce porous Ag@HNTs-CS sponges. The lumen-confined synthesis generated uniformly distributed Ag nanoparticles in the HNT lumens, which reduced aggregation and direct cell contact, thereby lowering toxicity and enabling sustained Ag + release. The composite exhibited triple antibacterial functionality, combining bactericidal effects mediated by chitosan, Ag + sustained release, and enhanced photothermal activity under 808 nm irradiation, strongly inhibiting E. coli and S. aureus . In a diabetic rat model with infected full-thickness skin defects, these sponges significantly promoted wound healing. Mechanistically, the sponges reduced TNF- α , increased IL-10 and VEGF, mitigating inflammation while enhancing neovascularization and collagen deposition. The confined-synthesis of metal nanoparticles within the HNT lumens and incorporation into a biopolymer matrix ensures sustained metal ion release, high photothermal performance and bioactivity, which offer a promising strategy for infected wound management.

Exploring low-cost and earth-abundant catalyst to efficiently release clean H 2 from solid hydrogen storage materials is an appealing solution for exhausted fossil fuel and its associated environmental issue. Halloysite (Hal) nanotubes are regarded as promising alternative catalyst support for expensive synthetic support materials due to their low cost and abundant resource. Herein, we report a simple and controllable one-pot reaction followed by chemical reduction approach to manufacture Ni, Co, P hybrids on Hal as high-efficient and non-noble metal catalysts for hydrolysis of ammonia borane (AB). It is revealed that ultrafine Ni 0.13 Co 0.87 P nanoparticles with diameter of 1.4 nm are homogenously anchored on Hal surface with excellent stability. The synergy among Ni, Co and P in Ni 0.13 Co 0.87 P effectively enhances their interaction with AB, resulting in reduced activation energy (41.8 kJ mol −1 ) and consequently significant boost of hydrolytic catalytic activity (TOF 47.5 mol H2 mol cat −1 min −1 ). A proposed mechanism demonstrates water molecules involve in the hydrolysis reaction and the rate-determining step is the O H cleavage in H 2 O. This work affords a prospective idea for the exploiting of Hal as well as new point of view for the reasonable design of low-cost AB hydrolysis catalyst.

The commercialization of lithium-sulfur (Li–S) batteries is primarily hindered by the polysulfide shuttle effect and sluggish reaction kinetics. Engineering a host material that synergizes efficient polysulfide confinement with high electrical conductivity, through a simple and potentially scalable process, remains a key challenge. Here, we demonstrate a facile, one-pot hydrothermal strategy to cost-effectively convert abundant natural halloysite clay into a mesoporous silicon-carbon composite (MHSC). This process effectively establishes an intimate Si – C bonded interface between the conductive carbon network and the polar silica framework, inherited from the mineral precursor. The resulting MHSC host exhibits excellent electronic conductivity (0.011 S cm −1 ) and strong polysulfide adsorption. When evaluated as a sulfur cathode, the MHSC/S composite delivers a high initial capacity of 1213 mAh·g −1 at 0.2 C and, more importantly, exceptional long-term stability with a negligible capacity decay rate of only 0.089% per cycle over 700 cycles at 1 C. This work provides a commercially viable and environmentally benign route for manufacturing high-performance Li–S battery cathodes by upcycling natural clay resources.

The development of high-performance energy-saving insulation materials is significant for reducing building energy consumption and promoting carbon neutrality. Aerogels show great potential in energy-saving insulation. However, their high preparation cost and poor mechanical properties limit their application. Here, based on a simple freeze-drying strategy, a halloysite nanotubes (HNTs)/polyvinyl alcohol (PVA) composite aerogel is achieved via low-cost and degradable industrial raw material. In particular, a simple process for changing the properties of HNTs/PVA composite aerogels by regulating the solid concentration. As a result, stable covalent cross-linking and hydrogen bonding structure between HNTs and PVA, long-range ordered pore structure with high porosity (97.6%), low density (0.12 g/cm 3 ), and low thermal conductivity (44.333 mW/m K) endow the HNTs/PVA composite aerogel high compressive strength (3.33 MPa), lightweight, and highly efficient thermal insulation properties. This work offers an attractive material for building insulation and carbon neutral.

In this work, the novel mixed-dimensional nanofiltration membranes [halloysite nanotubes (HNTs)/Kevlar aramid nanofiber (KANF)] with the ability to separate small-molecule dye/salt mixtures were prepared by comprising the rigid HNTs and the soft KANF. The considerable sieving in separating low-molecule dyes from dye/salt mixture solution was designed via the provision of additional channels for water molecules and salt ion transport via the special structure of the hollow structure of HNTs. The optimal 30% HNTs/KANF membrane displayed an eightfold water flux (39.2 L m–2 h–1) of the HNTs-free membrane, the low rejection of salts (21.7% for Na2SO4 and 7.7% for NaCl), and high rejection of various dyes (98.7% for Coomassie brilliant blue G-250, 95.3% for Congo red, 99.5% for Eriochrome black T, and 98.0% for Tropaeolin O). Besides, owing to the hydrophilicity of HNTs and the highly ordered and compact structure of KANF, the HNTs/KANF mixed-dimensional membrane showed excellent antipollution performance and long-term stability. This study provides some ideas for improving the permeability and selectivity of nanofiltration membranes by adding nanomaterials with special structures.

The development of wound dressings with hemostatic and antibacterial properties has attracted great attention. In this study, we prepared a multi-functional natural substance sponge (CMC/Ser-Ag/HNT) composed of carboxymethyl chitosan (CMC), sericin-silver nanoparticle (Ser-Ag), and halloysite (HNT). CMC/Ser-Ag/HNT sponge was demonstrated to bear desired hygroscopicity, porosity, compressive strength and compressive stability, cytocompatibility, and hemocompatibility. The mechanical properties (compressive strength of 100 kPa) and hemostatic capacity (hemostasis time of 15 ± 3 s in the liver injury model and 12 ± 3 s in the caudal injury model) were enhanced by introducing HNT into the CMC sponge. Ser-Ag was synthesized in situ via the redox nature of tyrosine residues in sericin in a “one-step, green” way to enhance the antibacterial activity of the hybrid sponge against Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ). In addition, the rat full-thickness skin defect model experiments demonstrated that the CMC/Ser-Ag/HNT4 sponge significantly promoted epithelialization and collagen formation. Immunofluorescence staining assays revealed that the composite sponge reduced inflammation by downregulating the expression of IL-6 and enhanced angiogenesis by upregulating VEGF expression. All the findings demonstrated the great potential of CMC/Ser-Ag/HNT sponge as versatile clinical wound dressing, especially for hemorrhagic and infected wounds.

In this study, the halloysite nanotubes (HNT) were incorporated into chitosan (CS) to prepare CS/HNT composite film by solution-casting method. Different HNT contents were studied in relation to the morphological, optical, mechanical, barrier and thermal properties of CS/HNT composite films. After incorporation of HNT, the CS/HNT composite films showed improvement in UV light shielding, barrier against water vapor and oxygen, mechanical strength and thermal stability as well as achievement of ethylene scavenging property. Especially, when 5 wt% HNT were added, more homogenous distribution of HNT in CS matrix was observed by SEM, resulting in 169.9% increase in tensile strength, 52.94% decline in oxygen permeability and 4.07 times enhancement in the ethylene scavenging capacity at 100 kPa pressure compared with pure CS film. Moreover, the obtained film with 5 wt% HNT effectively maintained the freshness of bananas and cherry tomatoes under ambient conditions. This study demonstrated that the CS/HNT composite films could be used as active food packaging material to extend the shelf-life of fresh fruits and vegetables.

Natural halloysite nanotubes (HNTs) have attracted great interest as smart nanocontainers of corrosion inhibitors. The adsorption behavior of corrosion inhibitors on HNTs will affect their loading capacity, a crucial property of smart nanocontainers. This work modified the surface of HNTs by preadsorbing metal cations (M2+: Fe2+, Zn2+, or Cu2+) to improve the adsorption of benzotriazole (BTA) on HNTs. The results based on the thermal gravimetric analysis showed that the loading capacities of BTA in Fe2+-, Zn2+-, and Cu2+-adsorbed HNTs were 8.25, 8.39, and 9.74 wt %, respectively, which are significantly higher than those in pristine HNTs of 4.57 wt %. Furthermore, density functional theory calculations exhibited that the adsorption energies of BTA on the M2+-adsorbed surfaces increased compared to that on the clean surface. Notably, the increasing trend of adsorption energies is in good agreement with that of measured loading capacities. Moreover, the presence of metal cations significantly enhances the charge transfer between BTA and the surface. The density of states analysis indicated that the adsorbed metal cations shifted the valence bands of the surface close to the Fermi level, thereby enhancing the coupling between the occupied bands of HNTs and the unoccupied orbitals of BTA.

MXene two-dimensional (2D) laminate membranes have attracted many researchers in the field of membrane separation due to its adjustable interlayer spacing. However, MXene 2D laminate membranes has been inability to achieve dye desalination due to simultaneous rejection of both dyes and salts in salt-containing dye. The looser MXene/C-HNTs composite forward osmosis (FO) membrane was successfully prepared via vacuum filtering, in which halloysite nanotubes modified with cetyltrimethylammonium bromide (C-HNTs) and MXene (Ti 3 C 2 T x ) nanosheets were self-assembled by electrostatic interactions. The insertion of C-HNTs effectively increased the interlayer spacing and enhanced the compression resistance of the composite membranes. With a mass ratio of 1:3 between Ti 3 C 2 T x nanosheets and C-HNTs, the composite membrane's pure water flux was raised to 191.4 L/(m 2 ·h). The insertion of C-HNTs not only enabled the composite membrane to keep a superior dye rejection rate (CR rejection rate >99%), but also effectively reduced the rejection rate of monovalent salt (NaCl <5%) and divalent salt (<13% and <10% for Na 2 SO 4 and MgSO 4 , respectively).

In this study, a microcapsule, with gold nanoparticles dispersed on enlarged halloysite nanotube (HNTs) was prepared for encapsulating ionic liquid 1-hexyl-3-methylimidazolium bis(trifluormethylsulfonyl)imide ([HMIm][NTf 2 ]). The thermal conductivity and mechanical properties of the PBO/PTFE fabric/phenolic resin composite liner improved after incorporating [HMIm][NTf 2 ]@HNTs/Au microcapsules. Pin-on-disk wear tests (55 MPa and 0.8 m/s for 120 min) demonstrated that the wear rate decreased from 9.4 × 10 −15 m 3 /(N⋅m) to 3.9 × 10 −15 m 3 /(N⋅m) when the filler content up to 2.0 wt% was added to a pure composites. This was attributed to a 40 nm adaptive tribofilm constructed on the counterpart surface due to filler.

Constructing heterojunction photocatalyst is an effective method to enhance the separation of photogenerated electron and hole, which significantly improves ability of visible light response. In this study, calcination methods have been proposed to prepare highly efficient magnetic ternary photocatalyst g-C 3 N 4 /TiO 2 -MnFe 2 O 4 halloysite. It showed an enhanced photocatalytic degradation for dyes (crystal violet) and nonsteroidal anti-inflammatory drugs (acetaminophen) under vision light irradiation. Compared to pure g-C 3 N 4 , TiO 2 , MnFe 2 O 4 halloysite and binary g-C 3 N 4 -MnFe 2 O 4 halloysite, the optimized ternary g-C 3 N 4 /TiO 2 -MnFe 2 O 4 halloysite displayed enhanced photodegradation efficiency with 91.1% removal of crystal violet (10 ppm) in 90 min under visible light irradiation, the optimized ternary g-C 3 N 4 /TiO 2 -MnFe 2 O 4 halloysite composite showed significantly enhanced photocatalytic activity with more than 79.1% removal of acetaminophen (10 ppm) within 90 min under visible light. The photocatalytic mechanism was identified through the free radical quenching experiment. The heterojunction photocatalyst could be easily recovered by an extra magnetic field and reused several times without any obvious deterioration in catalytic activity. Besides, the ternary heterojunction also exhibited antibacterial ability against Escherichia coli . The superior photocatalytic performance of composite should be mainly attributed to both the improvement of light harvesting as well as the enhanced separation and transfer efficiency. It is expected that this novel ternary visible-light responding composite would be a promising candidate material for organic pollutants degradation and bacteria inactivation.
