The single-atom M-N-C(M typically being Co or Fe)is a prominent material with exceptional reactivity in areas of catalysis for sustainable energy.However,the formation of metal nanoparticles in M-N-C materials is coupled with hightemperature calcination conditions,limiting the density of M-Nx active sites and thus restricting the catalytic performance of such catalysts.Herein,we describe an effective decoupling strategy to construct high-density M-Nx active sites by generating polyfurfuryl alcohol in the MOF precursor,effectively preventing the formation of metal nanoparticles even with up to 6.377%cobalt loading.This catalyst showed a high H2 production rate of 778mLgcat−1 h−1 when used in the dehydrogenation reaction of formic acid.In addition to the high density of the active site,a curved carbon surface in the structure is also thought to be the reason for the high performance of the catalyst. 展开更多

The development of formic acid dehydrogenation materials with high activity and low cost is key to realizing hydrogen energy utilization.Herein,we describe a specific low-loading strategy to construct a high-activity Co atom site catalyst for this reaction.Under optimal conditions,the formic acid dehydrogenation performance of Co─Fe dual-atom catalyst(turnover frequency of 2,446.8 h−1,hydrogen production rate of 1,015,306.1 mL gCo−1h−1)was 300 times greater than that of commercial 5%Pd/C.High-angle annular dark-field scanning transmission electron microscopy and X-ray absorption fine structure spectra,combined with theoretical calculations,confirm that the presence of different active sites(Co single-atom,Co-Co dual-atom,Co─Fe dual-atom)in catalysts is the key factor affecting their catalytic activity.These findings provide a strong scientific basis for the development of single-atom and dual-atom catalysts. 展开更多

"Environmental penalties"are the primary policy tool for implementing environmental regulations and serve as an external force to compel companies to take key measures in order to achieve the goals of the Paris Agreement.Currently,research on environmental regulation primarily focuses on policy effect evaluation.However,the way companies respond to external pressure from environmental penalties and implement a series of control measures has not been fully explored in the academic field.Based on this,this paper uses the LDA topic model and content analysis method to systematically review the annual reports of 1,151 listed companies in China that were subjected to environmental penalties in 2024.The study conducts an in-depth identification of the internal administrative responses,control goals,and major measures of these companies after the environmental penalties were implemented.The findings reveal that after the imposition of environmental penalties,the internal administrative response of companies focuses on achieving"compliance emissions",with control goals specified down to individual"units",and the main measures remain centered on"fine-tuned monitoring".In the future,companies under close monitoring by environmental authorities should adopt more innovative and effective measures that balance efficient production with the fulfillment of environmental responsibilities. 展开更多
