A green and scalable strategy has been developed for the synthesis of lignin-derived Zn single atom/N-codoped porous carbon(LCN@Zn-SAC)containing similar ZnNx sites with carbonic anhydrases.This catalyst exhibits superior activity on theα-alkylation of ketones with alcohols via borrowing hydrogen strategy(TON up to 15 h^(−1))than most of previously reported works.The dehydrogenation of benzyl alcohol is the rate-determining step based on kinetic experiment results.According to experimental and theoretical calculation results,Zn electron density is inversely proportional to reaction energy barriers,because Zn sites with less positive charge(ZnN_(4) and ZnN_(3)C)in Zn-SACs display better borrowing hydrogen ability than other Zn sites.Furthermore,this catalyst can be recycled by simple centrifugation,which can be reused at least 8 runs with no obvious lose in activity.To the best of our knowledge,this is the first example of non-noble metal-SAC-catalyzedα-alkylation via borrowing hydrogen strategy.

A facile,gram-scale and sustainable approach has been established for the synthesis of single-atomic-site iron on N-doped carbon(Fe_(SA)@NC-20A)via the pyrolysis of aniline modified FeZn-ZIFs,in which the synthesis of zeolitic imidazolate frameworks(ZIFs)can be accomplished in water at room temperature,and no acid etching is required.The as-synthesized catalyst exhibits better performance on the chemoselective hydrogenation of nitroarenes with a broad substrate scope(turnover frequency(TOF)up to 1,727 h^(-1),23 examples)than most of previously reported works.Based on high-angle annular dark field scanning transmission microscopy(HAADF-STEM)images in combination with X-ray photoelectron spectroscopy(XPS),X-ray absorption spectroscopy(XAS),electron spin resonance(ESR),and Mossbauer spectroscopy,Fe is dispersed as single atoms via forming FeNx(x=4-6).This work not only determines the active sites of FesA@NC-20A for hydrogenation(FeN4),but also proposes tentative pathways for both N-H activation of hydrazine and the reduction of nitroarene on FeN4 site,both of which are the key steps for the hydrogenation of nitroarenes.In addition,this catalyst shows excellent stability,and no significant activity degradation is observed when recycling for 10 times or restoring in air for 2 months.

Porous carbon materials have attracted much attention in the field of organic synthesis in recent years,due to their tunable properties,excellent catalytic activity and stability.Biomass-based carbohydrates emerge as an ideal precursor for the generation of these materials owing to their renewability,low cost,non-toxicity and high content of functional groups.Thus,carbon materials prepared from carbohydrates is of considerable importance for the sustainable development of organic chemistry.The present review not only summarizes recent examples of carbohydrate-derived porous carbon material-catalyzed organic reactions including the oxidation,hydrogenation,cross-coupling,esterification and condensation reactions,but also introduces the preparation and functionalization strategies of these materials.Furthermore,the challenges and opportunities of organic synthesis over these sustainable materials have also been addressed.This review will stimulate further research on exploring novel carbohydrate-derived porous carbon materials and new sustainable organic synthetic processes over these materials.

Nanoparticles(NPs)have already been widely used in catalysis,antibacterial and coating fields.Compared with the traditional toxic and harmful reducing reagents,green synthesis of NPs by using plant extracts is not only environmental-friendly and cost-effective but also conducive to the multi-level and efficient utilization of wild plant resources.In this study,the aqueous extracts from Sorbus pohuashanensis(SP)and Aronia melanocarpa(AM)fruits were used as the reducing and protective reagents for synthesizing Au/AgNPs,with the characteristics of originality operation and high repeatability.The SP/AM fruit extracts functionalized Au/AgNPs were characterized by UV-vis spectroscopy(UV-vis),transmission electron microscopy(TEM),energy dispersive spectroscopy(EDS),scanning electron microscope(SEM),X-ray diffraction(XRD)and Fourier transform infrared spectroscopy(FTIR).UV-vis spectrums showed the NPs peaks verified by the presence between 400–550 nm;TEM and SEM demonstrated NPs displayed approximately spherical structures;EDS confirmed the existence of Au/Ag elements;XRD measurements confirmed that the obtained NPs showed highly crystalline structures;FTIR demonstrated the fruits extracts were adsorbed on the surface of NPs.Primary experiments indicated that SP/AM fruit extracts functionalized-NPs could be used as the reagents for removing the organic dyes efficiently;Zone of inhibition tests(ZOI)explained that NPs have slow-release antibacterial activity.

Chlorophenols,used as the fungicides in leather,are strictly limited in leather products.In this work,a metal-organic framework material,zeolitic metal azolate framework-7(MAF-7),was first used to encapsulate laccase(Lac)to prepare MAF-7/Lac bio-composites with 98.5%immobilization yield.Afterward,Lac/MNP@MOM was formed by introducing the magnetic nanoparticles(MNPs)into the Lac@MOM.MAF-7 with better hydrophilicity and stronger pH buffering ability,exhibits good compatibility with laccase,which can reserve the activity of laccase after immobilization.Moreover,the porous structure of MAF-7 is favorable for the sufficient contact between laccase and substrates.Lac/MNP@MOM exhibited excellent activity when exposed to high temperature,extreme pH,and organic solvents,which also simplified complex recovery steps.Furthermore,the degradation rate of 2,4-dichlorophenol(2,4-DCP)could reach as high as 97%within 24 h by immobilized laccase,and after nine consecutive cycles of operation,enzyme activity could remain over 80%,which gives it the potential for practical applications.

Fractures have an extraordinarily negative impact on individuals'quality of life and functional status.Nonunion or disability of fracture is a major health issue with important clinical,social,and economic implications.1 Mesenchymal stem cells(MSCs)play an indispensable role in the initiation of the fracture repair process including the formation of a callus which is replaced by new bone.The use of MSCs in the treatment of fractures is very attractive as they can reduce the time of healing and occurrence of nonunion.
