Abstract To overcome the challenges of low catalytic activity and instability, a molecular weight engineering strategy coupled with oxidative ammonolysis is developed to synthesize CoRu‐based alloy catalysts distinct morphologies properties from biorefinery lignin. This approach effectively modulates intrinsic active sites exposes unsaturated nitrogen‐oxygen structures, thereby tailoring morphology defect structure carbon layers in catalysts. The as‐synthesized CoRu lignin precursors varying weights are designated as CoRu@OALC‐EtOAC, CoRu@OALC‐EtOH, CoRu@OALC‐Residual. featuring defect‐rich graphitic carbon‐coated structure, exhibited exceptional overall water‐splitting performance (1.48 V at 10 mA cm −2 ), significantly surpassing Pt/C || Ru/C (1.58 ). In contrast, CoRu@OALC‐Residual, its amorphous demonstrated remarkable stability (350 h 100 vastly outperforming (6 In‐situ Raman spectroscopy DFT calculations revealed that adsorb * H intermediates, accelerating process. strong adsorption also induces layer rearrangement, leading dissolution oxidation metal particles. provides universal method for biomass‐derived catalysts, establishing direct relationship between weight, catalyst morphology, electrocatalytic performance.

Abstract Producing room temperature phosphorescent (RTP) materials from biomass resources using a solvent free method is essential but hard to achieve. Here, we discovered that lignin dissolved well in the liquid monomer, 2-hydroxyethyl acrylate (HEA), due extensive hydrogen bonding and non-bonding interactions between HEA. Motivated by this discovery, developed system consisting of HEA urethane dimethacrylate (UDMA) for converting into RTP materials. With design, generated radicals upon UV irradiation, which initiated polymerization (as monomer) UDMA crosslinker). The as-obtained polymer network rigidifies activates humidity/water-resistant with lifetime 202.9 ms. Moreover, afterglow color was successfully tuned red after loading RhB via energy transfer (TS-FRET). Using these properties, as-developed material used as photocured multiple-emission inks, luminescent coatings smart anti-counterfeiting logo medicine bottle.

Producing thermoplastic room temperature phosphorescent (RTP) materials with closed-loop recyclability from natural sources is an attractive approach but hard to achieve. Here, the study develops such RTP materials, Poly(TA)/Cell, by thermally polymerizing thioctic acid in presence of cellulose. Specifically, polymerized poly(TA) forms strong hydrogen bonding interactions CNF, promoting formation molecular clusters between oxygen-containing units. The as-formed generate humidity- and excitation-sensitive green emission. Red afterglow emission also obtained integrating Poly(TA)/Cell together Rhodamine B (RhB) via energy transfer process. Attributed properties, as-obtained can be molded into flexible shapes uncompromised performance. Moreover, owing alkali-cleavable properties disulfide bond cellulose successfully recycled a yield 92.3% 81.5%, respectively. As demonstrator for potential utility, used fabricate information encryption.
