“…[38] For LLZTO@PDA, the N 1s spectrum shows an obvious red shift, and a new peak appears at 399.1 eV corresponding to LaN bonding. [39,40] The LaN bonding is detected in LLZTO@PDA, which attributes to the interaction between the La atoms of LLZTO and the amino groups of PDA via the Lewis acid-base effect. [39,41] Meanwhile, the La 3d spectrum of LLZTO@PDA displays two sets of peaks located at 855.1, 851.2 eV (La 3d 3/2 ), and 838.7, 834.5 eV (La 3d 5/2 ), which shift to low binding energy by 0.4, 0.2, 0.2, and 0.2 eV compared with the peaks of pure LLZTO, respectively (Figure S6, Supporting Information).…”

Improved Li‐Ion Conduction and (Electro)Chemical Stability at Garnet‐Polymer Interface through Metal‐Nitrogen Bonding

Organic‐inorganic composite solid electrolytes consisting of garnet fillers dispersed in polyvinylidene difluoride (PVDF) frameworks have shown promise to enable high‐energy solid‐state Li‐metal batteries. However, the air‐sensitive garnets easily form poorly‐conductive residues, which hinders fast Li‐ion exchange at the garnet‐polymer interface and results in low ionic conductivity. The highly alkaline residues trigger instant dehydrofluorination of PVDF to form unsaturated CC bonds, which are unstable against high‐voltage cathode materials. Here it is shown that, by applying a 10‐nm polydopamine coating on the residue‐removed garnet surface, the modified garnet filler becomes air‐stable and does not generate alkaline residues, so PVDF remains an intact structure. Surface characterizations reveal substantial metal‐nitrogen bonding between the La atoms of garnet and the amino groups of polydopamine, which can invite stronger adsorption of Li ions at the heterointerface. A new interparticle Li‐ion conduction mechanism is disclosed for the composite electrolyte, in which Li ions preferably migrate through the garnet‐polydopamine interface, forming an efficient ion‐percolation network. As a result, the composite electrolyte demonstrates an effective room‐temperature Li+ conductivity of 1.52 × 10–4 S cm–1 and a high cutoff voltage of up to 4.7 V versus Li+/Li to support stable operation of all‐solid‐state Li‐LiCoO2 batteries.

The carbon nanotubes (CNTs) were chemically grafted onto carbon fibers (CFs) to prepare a CNTs‐CF multiscale reinforcement. The tungsten disulfide/polyamide‐imide (WS2/PAI) composite coating, with PAI as the binder and WS2 as the lubricant filler, was prepared. The enhancement mechanism of CNTs‐CF on the high‐temperature tribological performance of WS2/PAI composite coating was analyzed. The addition of CNTs‐CF was found to increase the temperature of the 10% mass loss of PAI by 14.2°C, indicating its ability to improve the thermal stability of the coating. The hardness of the CNTs‐CF‐modified WS2/PAI composite coating was measured to be 17.9% higher than that of the WS2/PAI substrate. The incorporation of CNTs‐CF significantly improved the tribological performance of the WS2/PAI composite coating. Particularly at 200°C, the friction coefficient and wear rate of CNTs‐CF modified WS2/PAI composite coating were only 0.095 and 8.92 × 10−5 mm3/(N·m), respectively, which decreased by about 70.3% and 62.2% compared to the WS2/PAI substrate. Further analysis revealed that CNTs‐CF is firmly embedded within the WS2/PAI composite coating through the synergistic mechanism of mechanical interlocking and molecular adsorption. Furthermore, CNTs‐CF formed a stable lubricating film, ensuring the excellent friction and wear performance of the coating.Highlights The CNTs‐CF can mitigate the thermal degradation of PAI. The high‐temperature wear resistance of the coating was noticeably improved. The problem of CF easily detaching from the coating was resolved. The main components of the transfer film were analyzed.

“…Thus, a carrier for La species is imperative to develop La-containing phosphate adsorbent. During recent decades, many supporting materials, including clay minerals, 14 metal (hydr)oxides, 15 industrial wastes, 16 carbon-based materials, 17 inorganic-organic composites, 18 synthetic polymers, 19 and biomass, 20 were used to load La species for phosphate adsorption. However, there is still a need to develop La carriers with sustainable sources, low costs, easy preparation routes, and tunable physicochemical structures and surface functionalities.…”

Biochar has attracted increasing attention as the sustainable and structure-tunable carrier for lanthanum (La) species for diverse applications. Carbonated La species possesses a higher biocompatibility and a lower leaching potential than other commonly used La species, while less attention is paid on the application of carbonated La in phosphorus (P) adsorption. Herein, thermal air oxidation (TAO) was applied as a novel strategy for synchronously tuning the coordination environment and chemical species of La on biochar surface. The results demonstrated that TAO induced the coordination of La with oxidation-generated oxygenated functional groups (OFGs) and carbonation of La species by the oxidationgenerated CO 2 on the biochar surface. The batch adsorption results showed that the Q m of resultant biochar remarkably increased from 68.92 to 132.49 mg/g at 1 g/L dosage. It also showed a robust adsorption stability in pH 2−6, a strong resistance to the co-existing Cl − , SO 4 2− , NO 3 − , CO 3 2−, or HCO 3 − , a stable adsorption recyclability, and an ultralow La leaching potential. The P adsorption was dominated by ligand exchange-induced inner-sphere complexation. In practical swine wastewater, the resultant biochar composite (1 g/L) removed 99.87% of P from 92.3 to 0.12 mg/L at a practical pH of 7.12. The density functional theory calculation further revealed the significant role of the binding of carbonated La by the biochar surface OFGs in reducing the P adsorption energies, indicating the synergism between the oxygenated biochar carrier and the carbonated La in P adsorption. Finally, this study provided a novel route to synchronously tune the coordination environment and chemical species of La on biochar via a facile TAO process for high-efficient P adsorption from wastewater.
