The electrosynthesis of 2,5-furanodicarboxylic acid (FDCA) from 5-hydroxymethylfurfural (HMF) oxidation is one of the most promising means for the production of bioplastic monomers. In this work, we constructed a novel P-doped Ni<sub>3</sub>S<sub>2</sub> and Ni heterojunction on nickel foam (P-Ni<sub>3</sub>S<sub>2</sub>/Ni/NF) using electrodeposition methods and thermal sulfuration techniques as a bifunctional catalyst for the simultaneous anodic oxidation of HMF to FDCA (HMFOR) and the cathodic hydrogen evolution reaction (HER). On one hand, the synergistic promotion of P doping and the heterojunction of Ni<sub>3</sub>S<sub>2</sub> and Ni accelerated electron transfer, and on the other hand, the structure of three-dimensional microsphere stacking on NF surface to form macropores enhances the exposure of catalytically active sites. The prepared P-Ni<sub>3</sub>S<sub>2</sub>/Ni/NF exhibited remarkable performance with high HMF conversion (99.2 %), FDCA yield (98.1 %), and Faraday efficiency (98.8 %), and excellent stability with good product selectivity for 7 consecutive cycles, which stands at a higher level than majority of previously published electrocatalysts. Furthermore, P-Ni<sub>3</sub>S<sub>2</sub>/Ni/NF also shows a significant response in HER. By using HMFOR and HER as the anodic reaction and cathodic reaction, respectively, the biomass upgrading and hydrogen production can be carried out simultaneously. The synthesized P-Ni<sub>3</sub>S<sub>2</sub>/Ni/NF only need a voltage of 1.31 V to achieve a current density of 10 mA/cm<sup>2</sup> in a two-electrode system of HMFOR and HER, which is much lower than that of 1.48 V in OER and HER process, thus potentially reducing the cost of this process.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 9","pages":"Article 111271"},"PeriodicalIF":9.4,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, a variety of magnetic-driven strategies have been developed to dynamically regulate liquids within enclosed spaces, especially through physicochemical mechanisms. These approaches provide efficient control over liquid behavior by leveraging magnetically induced chemical changes, structural deformations, and dragging motions, opening new opportunities for flexible and versatile fluid management.

Herein, we demonstrate that organic nanoscintillators, when combined with checkpoint blockade immunotherapy and exposed to X-ray-induced RDT, can trigger cutaneous irAEs. To address this challenge, we engineered diselenide-bridged silicon coatings on organic nanoscintillators, fine-tuning the steric hindrance of the protective layer by varying its thickness. This strategy enables radiation-triggered reactive oxygen species (ROS) generation while mitigating off-target phototoxicity through neutralizing ROS. By optimizing the steric hindrance to precisely control energy transfer between the organic nanoscintillators and surrounding oxygen molecules, we effectively reduce phototoxicity and mitigate off-tumor effects through engineered surface protection. Under X-ray irradiation exposure, the steric hindrance is rapidly deactivated through the dissociation of the silicon coating, activating RDT and inducing abundant ROS generation within tumor cells. In an orthotopic 4T1 breast cancer model, intravenous administration of these surface-engineered nanoscintillators, combined with anti-programmed death-1 (anti-PD-1) antibodies, results in robust anti-tumor immune responses, while minimizing cutaneous irAEs.
