PC waste, prevalent in natural and marine environments, poses significant environmental and human health risks. This study introduces a novel recycling approach aligned with circular-economy principles, using a commercial zeolite catalyst. The unique topology and textural properties of zeolites grant access to their pores and acid sites, enabling exceptional catalytic efficiency in converting PC waste into valuable phenol and acetone. The cover depicts PC waste entering the zeolite pores, where it undergoes catalytic transformation by acid sites, highlighting the process's potential to address environmental challenges and contribute to sustainable chemical production.

Here, we present a facile, environmentally friendly, cost effective and scalable method to address this problem by uniformly fluorinating the surface of cathode materials with a mild fluorinating agent (CHF3) using a gas flow-type reactor. CHF3, well known as a potent greenhouse gas, is successfully transformed into a stable ~2 nm LiF homogenous layer by converting the adventitious Li2CO3 layer covering the surface of the vast majority of layered-oxide cathode materials. The fluorination mechanism and the interface stability of the LiF coating layer is systematically studied on LiNi0.8Co0.15Al0.05O2 using synchrotron surface spectroscopy techniques, operando XRD and TEM. In addition, we demonstrate improved electrochemical cycling performance of the LiF coated LiNi0.8Co0.15Al0.05O2 when cycled up to 4.5 V where the impedance and overpotential decrease by 30% and 100 mV respectively after 100 cycles, with a capacity retention better than 94% and improved rate performance at high current density. Furthermore, the universality of the fluorination approach is validated further on Ni-rich LiNi0.85Co0.1Mn0.05O2 cathode material cycled up to 4.8 V.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402057"},"PeriodicalIF":7.5,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report the plasma-electrified synthesis of composition-controlled FeAu bimetallic nanoparticles, specifically engineered to enhance the redox catalytic performance through precise tuning of their chemical states. Utilizing atmospheric-pressure microplasmas, FeAu nanoparticles were synthesized under ambient conditions without the need for reducing agents or organic solvents, thereby providing a green and sustainable approach. The catalytic activity of the FeAu nanoparticles was significantly influenced by the oxidation states of Au modulated by adjusting the process. This precise tuning directly affects the oxidation-reduction potential (ORP) of the nanoparticles, driving their superior degradation performance. The FeAu-1.52 sample exhibited the highest normalized rate constant (k=46.3 s-1 g-1), attributed to an optimal Au+/Au0 ratio that facilitates efficient electron transfer and redox cycling during the catalytic reduction of 4-NP to 4-aminophenol (4-AP). Beyond 4-NP, the FeAu nanoparticles demonstrated robust catalytic degradation of multiple dye pollutants for industrial wastewater treatment. This study elucidates the critical role of chemical state tuning in determining redox performance and presents a promising nanotechnology platform for sustainable environmental remediation.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402327"},"PeriodicalIF":7.5,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142833299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, NRR still faces major challenges due to direct dissociation of the strong N≡N triple bond, poor selectivity, as well as other issues related to the inadequate adsorption, activation and protonation of N2. In nature's nitrogen fixation, microorganisms are able to convert N2 to ammonia at ambient temperature and pressure, and in aqueous environment, thanks to the nitrogenase enzymes. The core NRR performance is achieved with sulfur-rich Fe transition metal clusters as active site cofactors to capture and reduce N2, with optimum performance found for Fe-Mo clusters. Because of this reason, artificial analogs in Fe-Mo coordination chemistry have been explored. However, the studies of sulfur coordinated Fe, Mo catalysts for electrocatalytic ammonia synthesis. In this review, the recent progress of Fe-Mo sulfur-bridged catalysts (including sulfur-coordinated single-site catalysts in carbon frameworks and MoS2-based catalysts) and their activities for the ammonia synthesis from nitrate reduction reaction (NO3-RR) and nitrogen reduction reaction (NRR) are summarized.

A mixed Bi-Zn catalyst and a 71% bio-based isocyanate are exploited at this aim through multivariate chemometric approaches, namely Design of Experiment (DoE). DoE allows us to investigate the effect of different formulation factors on selected parameters, such as the film flexibility and transparency or the gel time. More in detail, it is found that a low amount of Zn-rich catalytic mixture leads to a ready-to-market polyurethane only when a fossil-based isocyanate is used. Differently, PUs formulated with bio-based isocyanate, albeit showing a higher bio-based content, present an insufficient optical purity, jeopardizing their market acceptability. Nevertheless, adding a negligible amount of a specific long chain fatty acid as reactivity modulator in the formulation leads to a bubbles-free and ready-to-market resin showing an impressive 65% w/w content of circular and bio-based components.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402451"},"PeriodicalIF":7.5,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
