The production of ultra-low sulfur clean fuels holds global significance for improving energy efficiency and reducing environmental pollution. Photocatalytic aerobic oxidative desulfurization（PODS） offers an attractive approach to efficiently remove refractory heterocyclic aromatic sulfur compounds under mild conditions. However, the sluggish charge dynamics,insufficient molecule activation, and slow mass transfer within photocatalysts restrict the overall desulfurization efficiency,hindering the widespread application of this technology. Herein, we developed a defective g-C3N4（M1U3CN） photocatalyst with bridged N3Cvacancies and hierarchical porous structures to address these limitations. This catalyst not only demonstrates outstanding dibenzothiophene（DBT） removal efficiency of 99.6% for model oil with high conversion and selectivity but also achieves complete sulfur removal from gasoline as well as 96.7% sulfur removal for distilled diesel at room temperature,successfully achieving ultradeep aerobic oxidative desulfurization. The introduction of rich N3Cvacancies and abundant micromeso-macroporous distribution in M1U3CN enhances kinetic efficiencies by promoting charge carrier separation, mass transfer,and molecular activation simultaneously; resulting in exceptional PODS performance. This work provides a collaborative strategy to overcome kinetic challenges in aerobic oxidative desulfurization via defect and structural engineering of the catalyst.

Thermally activated delayed fluorescence (TADF) depends on reverse intersystem crossing (RISC) from the lowest triplet to the singlet excited state. Here, a macrocyclization strategy is developed to achieve TADF emission by promoting RISC. 5-(9Hcarbazol-9-yl) isophthalonitrile, a fluorescent molecule, is coupled with 1,4-dimethoxybenzene by methylene bridges to form a macrocycle with TADF emission. Experimental results and theoretical calculation indicate that the macrocyclization strategy contributes to RISC promotion and suppression of nonradiative decay, resulting in effective TADF emission transformed from prompt fluorescence. Three TADF luminophores are cyclized with the same strategy, and an enhanced TADF emission of up to3.8 folds is observed. The marriage of macrocycle chemistry and luminescent materials will provide new guidelines for designing efficient TADF materials.

Establishing supply chains for future ammonia energy systems requires the development of efficient materials and processes for ammonia production under mild conditions. Recent researches disclose unique functionalities of binary alkali and alkaline earth metal hydrides in mediating ammonia synthesis. Thanks to the rich compositional and structural properties of the metalhydrogen system, we herein report that LiBaH3, as a narrow band gap perovskite hydride, exhibits a strong response to visible light illumination. Specifically, hydridic hydrogen undergoes reductive elimination of producing H2and creates an electron-rich surface. Such an environment favors dinitrogen fixation to form N–H bonds. Based on this chemical property, a chemical looping ammonia synthesis process mediated by LiBaH3and driven by both photo and thermal energies was proposed and *** work demonstrates that hydride perovskites are promising candidates for mediating photo-assisted nitrogen fixation reactions.
