“…Porous polymers (PPs) have been regarded as a kind of promising and unique materials, which have received considerable interests 24,25 . PPs can be designed to be with multiple functionalities by introducing various functional monomers, which endows them with novel properties and extensive applications in adsorption 26,27 , separation 28,29 , catalysis 30 , hydrogen storage 31 and so on. To the best of our knowledge, there were negligible researches on the synthesis and application of PPs using biomass polyphenols sources on Cs + removal.…”

in this work, a series of polyphenol porous polymers were derived from biomass polyphenols via a facile azo-coupling method. the structure and morphologies of the polymer were characterized by Bet, teM, SeM, XRD, tGA and ft-iR techniques. Batch experiments demonstrated their potentialities for adsorptive separation of cs + from aqueous solution. Among them, porous polymers prepared with gallic acid as starting material (GApp) could adsorb cs + at wide pH value range effectively, and the optimal adsorption capacity was up to 163.6 mg/g, placing it at top material for Cs + adsorption. GApp exhibited significantly high adsorption performance toward Cs + compared to na + and K + , making it possible in selective removal of cs + from ground water in presence of co-existing competitive ions. Moreover, the cs-laden GApp could be facilely eluted and reused in consecutive adsorption-desorption processes. As a result, we hope this work could provide ideas about the potential utilization of biomass polyphenol in environmental remediation. Growing concern about the remediation of radioactive waste generated from nuclear power plants and unforeseen accidents have been given worldwide for the sake of human health and environmental issues 1-4. Among them, radio-isotope 137 Cs is considered as the most hazardous nuclide due to the serious gamma radiation, long half-life as well as high solubility being an alkaline element 5,6. The generation of hazardous 137 Cs by nuclear waste and unforeseen nuclear plant accidents has seriously threatened the global environment and human health. In addition, long-term exposure to 137 Cs-contanining wastewater would lead to horrible diseases such as cancer, leukemia and genetic disorder 7. For example, the accidents occurred at Chernobyl in 1986 and Fukushima in 2011 severely impacted the local environments, and the surrounding areas are still classified as dangerous regions due to the leakage and serious emission of 137 Cs and other radio-isotopes 8,9. Therefore, effective techniques for the decontamination of radioactive Cs + from wastewater are indispensable and highly desirable. So far, considerable efforts have been made to explore available methodologies for hazardous Cs + removal from radioactive wastewater, such as liquid-liquid solvent extraction, chemical precipitation, electrochemical techniques and adsorption process 10-12. Taking disposal cost and removal efficiency into consideration, adsorption is considered as one of the most effective and clean techniques, and has been widely used in Cs + removal. To date, Prussian blue (PB) analogues 12,13 , titanate nanomaterials 14 , metal oxides and sulfides 15 , natural zeolites 16 , ammonium molybdophosphate 17,18 and other adsorbents 19 were developed and used for the removal of Cs + from radioactive effluents. Unfortunately, they still suffered from several problems, such as considerable preparation cost, unsatisfactory adsorption performance and insufficient stability, thus majority of the adsorbents aforementioned were not environment...

“…Han et al synthesised a biomass-based porous organic polymeric catalyst 62 with multifunctional sites and hydroxyl and carboxylic acid groups obtained from tannic acid (Scheme 36). 191 In the presence of silver nanoparticles, catalyst 62 could efficiently catalyse the carboxylative cyclisation of propargyl alcohols with carbon dioxide. In addition, after adsorbing iodine (consequently forming I 3which acts as a nucleophile), catalyst 62 catalysed the reaction of epoxides with carbon dioxide to produce cyclic carbonates, but required harsh reaction conditions (150 o C and 30 bar of carbon dioxide).…”

“…[49][50][51][52] But all the reported catalysts were employed under homogeneous reaction conditions whereas our catalyst can perform the reaction under heterogeneous condition, hence recyclability and reusability of the catalyst offers added advantages. Earlier several methodologies have been published for the catalytic synthesis of α-alkylidene cyclic carbonates through CO 2 fixation by silver metal-containing catalysts, [53][54][55][56][57][58][59][60] The main drawbacks of those catalytic protocols are: use of high CO 2 pressure; [53,56,[59][60] requirement of non greener solvent; [54][55][56][57][59][60] homogeneous catalytic condition; [55,57,58,60] large reaction duration etc. Here our catalytic system worked under 1 bar CO 2 pressure, at room temperature and solvent free heterogeneous reaction conditions.…”

The synthesis of important organic chemicals through sustainable and green methods is always demanding for the scientific community. Fixation of carbon dioxide for this purpose is very attractive as CO2 is non‐toxic, easily available, naturally abundant, recyclable, non‐flammable and an inexpensive C1 resource, and also the concentration of CO2 (most responsible greenhouse gas) is reduced. This article demonstrates the synthesis of silver nanoparticles (AgNPs) by an eco‐friendly method and incorporation of the particles into a covalent organic framework in order to obtain a sustainable heterogeneous catalyst, AgN@COF. The catalyst has been characterized in detail by FT‐IR,UV‐Vis. spectroscopy, FE‐SEM, TEM, EDAX, XPS, PXRD, ICP‐AES, TG‐DTA and N2 absorption‐desorption studies. The synthesized catalyst is able to fix CO2 to terminal propargylic amine and propargylic alcohol for the production of 2‐oxazolidinones and α‐alkylidene cyclic carbonates, respectively, through two different catalytic pathways. In both catalytic protocols, one atmospheric carbon dioxide was used. Production of α‐alkylidene cyclic carbonates occurred at room temperature and solvent‐free condition, and 2‐oxazolidinones were obtained under mild reaction conditions. Moreover, the catalyst is recyclable and reusable. Its catalytic efficacy was preserved even after the use of six consecutive catalytic cycles.
