However, the poor fast-charging and limited stable-cycling properties of starbon limits the broad applications of lithium-ion batteries (LIBs) in practical scenarios. Herein, a boron-tailored approach was proposed to promote Li-ion migration and retard capacity decay of starbon anode. A boron solid-solution phase such as BC2O was formed in the starbon framework by a simple pentaborate starch hydrothermal reaction and annealing process, and then boron quantum dots (BQDs) were confined within conductive boron-doped starbon. The electron-deficient BQDs endow the boronated starbon framework with superior electrochemical performance, vastly enabling the electrochemical activity of boron as well as providing more active sites for ion insertion and extraction, thus increasing capacity and improving ion charge/diffusion and transfer. As an anode material for LIBs, BQDs/Starbon anode exhibits a high discharge capacity of 928 mAh g-1 at 0.05 A g-1, and the reversible specific capacity remains at 238 mAh g-1 at 2 A g-1 after 1000 cycles, demonstrating excellent long-term cycling stability. After cycling at a high current density of 10 A g-1 to recover to the initial 0.5 A g-1, the electrode was still able to maintain a high capacity of 318 mAh g-1. The excellent lithium storage properties demonstrated the composite anode of BQDs and biomass starbon is feasible, providing more choices for the development of anode materials for lithium-ion batteries.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"726 ","pages":"141550"},"PeriodicalIF":9.6,"publicationDate":"2027-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943935","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}

However, the construction of ordered mesoporous CeO2 architectures through sustainable synthesis routes remains highly challenging. Metal-organic frameworks (MOFs) are promising sacrificial templates for the synthesis of oxides. Herein, we report a surfactant-regulated, alkali-metal-assisted aqueous strategy to construct ordered mesoporous CeO2 via UiO-66(Ce) templating. Pluronic was employed as a soft template, while inorganic bases (LiOH, NaOH, and KOH) were used to promote H2BDC deprotonation in water. The Li+, Na+, and K+ cations are believed to influence the self-assembly of UiO-66(Ce) framework (CeULi, CeUNa, and CeUK, respectively), leading to differences in the properties of the resulting particles. CeO2 derived from CeULi at low temperature, denoted as cCeULi, exhibited outstanding acetone conversion, reaching 90% at 207 °C. This is due to its mesoporous structure, the presence of Ce3+defects, and surface oxygen mobility. The cCeULi catalyst performed well over 10 cycles, averaging 87.9% efficiency over 25 h at 200 mg catalyst, 100 cc/min flow rate, and 600 ppm acetone. Also, cCeULi proved highly resistant to water vapor (5-10 vol%). In-situ DRIFTS analysis indicates that the acetone oxidation on cCeULi follows a Mars-van Krevelen mechanism involving lattice oxygen. Overall, the combination of morphological structure and surface chemical properties plays a key role in catalytic activity.

However, this process is often limited by the high energy barrier for hydrogen extraction from water, low oxygen solubility and diffusion, and poor selectivity for the two-electron oxygen reduction reaction (ORR), especially under alkaline conditions. Herein, we reported a synergistic photothermal-photocatalytic bilayer aerogel constructed with konjac glucomannan to integrate a photothermal lower layer of reduced graphene oxide (rGO) and a catalytic upper layer of keto-form anthraquinone covalent organic framework (Kf-AQ-COF). Owing to its hydrophobic mesoporous structure, the bilayer aerogel forms a robust gas-liquid-solid triphase interface on a porous substrate. Under alkaline conditions, the hydroxide clusters adsorbed onto ketone moieties can drive the anthraquinone-anthrahydroquinone cycle of Kf-AQ-COF for enabling electron transfer and H2O2 production. Meanwhile, the underlying rGO layer functions primarily as a localized photothermal converter and lightweight structural matrix, raising the interfacial temperature to accelerate reaction kinetics and driving rapid vapor escape without altering the intrinsic band structure of the top photocatalyst. As a result, this photothermal-synergistic triphase interface achieves an H2O2 production rate of 15.0 mmol m-2∙h-1 under air without sacrificial agents within 60 min, which is 1.43 times that of the conventional solid-liquid diphase system.
