However, conventional hydrogenation methods face significant safety concerns due to the use of high-pressure hydrogen. While photocatalytic transfer hydrogenation with water as the proton source represents a promising green alternative to traditional methods, its reliance on hole sacrificial agents has hindered the efficient utilization of photogenerated holes, failing to fully exploit the intrinsic oxidation potential. Herein, we report a novel photocatalytic water-donating transfer hydrogenation system that integrates the semi-hydrogenation of alkynes with the oxidation of glycerol over a TiO₂-supported palladium photocatalyst (Pd-TiO₂). This system achieves 96% conversion of phenylacetylene with 99% selectivity for styrene, alongside an excellent glycerol conversion rate (1.95 mmol g⁻¹ h⁻¹) to high-value-added products, including formic acid, dihydroxyacetone, and glyceraldehyde. Isotope-labeling experiments confirm that water serves as the hydrogen source for the semi-hydrogenation of alkynes. The Pd-TiO₂ catalyst exhibits remarkable stability, retaining its activity over four consecutive cycles and displaying a broad substrate scope, efficiently converting aromatic alkynes with electron-donating or withdrawing groups into alkenes with high yields and selectivity. This work provides a sustainable and cost-effective approach for alkene production and biomass conversion, aligning with the principles of green and sustainable chemistry.</div></div>","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":"28 24","pages":"Pages 10251-10259"},"PeriodicalIF":10.6,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148285365","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, its toxicity and disordered structure introduce environmental concerns and restrict sodium-storage performance. To address this issue, a dual-innovation strategy in both material and structure was proposed in this work. By coupling the rigid benzopyrone ring from natural naringenin with the three-dimensional network of lignin and employing the green aldehyde source glyoxylic acid as cross-linking agent, an environmentally friendly bio-based phenolic resin precursor (NLRG) was constructed, achieving complete substitution of toxic phenol and formaldehyde. Through the regulation of pyrolysis temperature, 1400 °C was identified as the critical condition for forming an ideal disordered structure. The resulting material exhibits a suitable interlayer spacing, abundant defects and nanopores, together with moderately developed graphitic microcrystals. Benefiting from this, it delivers high reversible capacity of 356.2 mAh g⁻¹ and initial coulombic efficiency of 84.2% in half-cell tests.

When assembled into a full cell with an O3-NaNi_1/3Fe_1/3Mn_1/3O₂ cathode, the energy density of 241 Wh kg⁻¹ is achieved, and the capacity retention remains 70.3% after 310 cycles. The comprehensive characterizations reveal stepwise sodium-storage mechanism described as “adsorption – insertion – insertion &amp; pore filling – pore filling”.

EB-loaded spheres (EB@MSs and EB@NSs) form <em>in situ</em> at the water/cyclohexanone interface without pre-fabricated carriers or external crosslinking.

However, it is still a challenge to regulate the biomass components <em>via</em> DESs to construct a multi-closed-pore structure within hard carbon. This work presents a novel neutral DES pretreatment approach based on hydrogen-bond competition for waste camellia shells to construct a hard-carbon anode for high-performance sodium-ion batteries. DES pretreatment selectively dissolves and removes amorphous components (partial lignin, hemicellulose, and amorphous cellulose), allowing cellulose chains to rearrange into a more ordered structure, thereby increasing cellulose crystallinity. A higher cellulose-to-lignin ratio in the precursor favors an increase in the closed-pore proportion and promotes the formation of closed-pore walls of the hard-carbon. By optimizing the DES treatment time to 0.5 h, the hard-carbon material (HC-0.50) pyrolyzed from the pretreated biomass exhibits a high closed-pore volume and abundant defect sites, which is beneficial for enhancing sodium storage capacity. Furthermore, the flake-like structure and the large interlayer spacing (0.378 nm) favor diffusion kinetics. Consequently, HC-0.50 achieves a reversible capacity of 304.2 mAh g⁻¹ at 0.1 C, which is 72 mAh g⁻¹ higher than that of the untreated sample (HC-0). Additionally, HC-0.5 delivers an initial coulombic efficiency of 81.52%.

However, HAA synthesis <em>via</em> an e-FDCArr has, until now, remained elusive. Herein, we report an efficient e-FDCArr process utilizing a metallic bismuth nanosheet electrode assisted by quaternary alkyl ammonium salts (QASs) in acidic media. A combination of systematic electrolysis, multi-modal physical characterization, and multi-scale computational modeling reveals that bismuth serves as the essential catalytic center, while specific symmetric, long alkyl chain QAS cations serve a dual role: they passivate the bismuth surface against acid-driven dissolution and act as a structural template that directs FDCA adsorption in a quasi-vertical configuration. This specific orientation facilitates the exposure of the reactive oxygen sites of FDCA directly to the bismuth surface for electron acquisition, driving a spontaneous, proton-coupled electron transfer and ring-opening process. Under optimized conditions, the bismuth nanosheet electrode was demonstrated, for the first time, to exhibit a remarkably high HAA yield (75.5 ± 3.3%) and selectivity (88.6 ± 3.9%) at −10 mA cm⁻².
