Although the presence of the built-in electric field will solve the problem of carrier complexation in photocatalytic systems to some extent. However, free carriers will quickly shield the stabilized electric field and lose its effect. Therefore, how to introduce the dynamic piezoelectric field into the photocatalytic system has become an imminent problem. Herein, we developed an overcoated, visible light responsive, piezoelectric-assisted photocatalytic system by depositing Bi2S3 photocatalysts with a narrow-band system onto the surface of highly piezo-responsive BaTiO3 nanorods (BTO NRs). The heterojunction structure, bound by Bi-O chemical bonding, enhances carrier transport efficiency under the influence of the piezoelectric field. In the degradation experiments, the first-order rate constant for the degradation of chlortetracycline hydrochloride (CTC) in the BTO NRs/Bi2S3 system with the optimal complex ratio was 0.0276 min−1, which was 3.1 and 7.8 times higher than that of BTO NRs and Bi2S3, respectively. Additionally, we deduced the degradation pathways of CTC through a combination of Density functional theory (DFT) calculations and Liquid Chromatograph Mass Spectrometer (LC-MS), evaluating the toxicity of the intermediates. This complex system, featuring a highly photo-responsive semiconductor as a photo-acceptor deposited on a piezoelectric semiconductor surface providing a dynamic built-in electric field, enhances carrier separation efficiency under optimal light energy utilization conditions. These findings present novel and effective strategies for addressing two primary challenges in photocatalytic systems: low spectral utilization and significant photogenerated carrier complexation. © 2024 Elsevier Inc.

High performance soft fiber-reinforced sodium alginate/polyacrylamide double-network hydrogels

Strong and stretchable hydrogels are in great demand but challenging due to the trade-off between the strength and stretchability. Here, we successfully prepared highly strong and stretchable sodium alginate/polyacrylamide（SA/PAM） double network（DN） hydrogels by using swollen calcium alginate fiber（CAF） as the first energy dissipating network. The swollen fibers contributed two functions: the homogeneous SA ionic crosslinkedpolymer networks and the soft fiber reinforcement. In contrast to the stiff fiber, the soft CAF provide more effective energy dissipation transferring from soft fiber to the liquid hydrogel. The as-prepared hydrogels demonstrated a high tensile strength（0.83 MPa）, high stretchability（4230 %）, and high toughness（15.7 MJ/m3）,as 5, 3 and 14 times of the SA/PAM hydrogels. This soft fiber-reinforced strategy offers a new way for preparing high-performance hydrogels, broadening their applications areas.

Porous aluminum borate ceramics are ideal candidates for high-temperature thermal insulation applications. In this work, lightweight, high strength and thermal insulating aluminum borate whisker-based porous ceramics with hierarchical pore structure were fabricated by the combination of freeze-gel casting and in situ reaction. The effects of B/Al ratio on the morphology of aluminum borate whiskers and the addition amount of agar on the pore structure and properties of aluminum borate whisker-based porous ceramics were investigated. The aluminum borate whisker-based porous ceramics exhibited a typical hierarchical pore structure, including macro pores formed by the growth of ice crystal in the freeze casting process and micro pores in pore walls formed by the overlapped aluminum borate whiskers generated from the in situ reaction of B4C and Al2O3. Results shows when the B/Al molar ratio was 6:9 and the addition amount of agar was 0.4 g, the resultant aluminum borate whiskerbased porous ceramics shows a low density（0.20 g/cm3）, high porosity（93.5 %）, high compressive strength（4.09 MPa） and low thermal conductivity(0.072 W/（m·K）), which can be regarded as a promising high temperature thermal insulation structural material.

Grafting modification is a common method for improving the specific properties of polysaccharides. Herein, we synthesised sodium alginate-g-poly (acrylic acid) (NaAlg-g-PAA) as a novel printing thickener via catalysis of horseradish peroxidase and hydrogen peroxide in the presence of acetylacetone. The synthesised products were characterised by Fourier Transform–infrared spectroscopy and polar nuclear magnetic resonance spectroscopy, which confirmed that the PAA was successfully grafted onto the hydroxyl groups at carbon atoms (C2) of sodium alginate. The optimal grafting percentage and grafting efficiency reached 51% and 96%, respectively. Compared with native sodium alginate, the grafted copolymer NaAlg-g-PAA exhibited better thermal stability, rheological and printing properties. This work provides an efficient and promising approach for modifying polysaccharides like alginates and could be used as an alternative to conventional chemical modification. © 2021 Society of Dyers and Colourists.
