This study experimentally evaluates the catalytic activity of over 20 environmentally friendly additive anions—including carboxylates, inorganics, and ammonium salts—for promoting magnesite and calcite formation during the carbonation of brucite [Mg(OH)2] and portlandite [Ca(OH)2] in aqueous slurries. Carbonation is driven by microwave (MW)-assisted heating at 100–200 °C under hydrothermal conditions, with CO2 partial pressures below 8 bar. Results reveal a significant enhancement in magnesite precipitation when additives are combined with MW energy, enabling crystallization at much lower temperatures. For calcite, MWs alone nearly double the precipitation yield, with further improvements in the presence of additives. Among promising catalyzers, chelating agents like citrate and tartrate increase induction times and reduce overall yield at higher concentrations. In contrast, additives forming simple ion pairs—such as acetate and sulfate—show improved performance with increased concentration. These findings highlight the importance of additive selection and MW energy in optimizing mineral carbonation for sustainable applications.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 9","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202500046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the catalytic potential in CO2RR, a theoretical study on phthalocyanine (H2Pc) and iron phthalocyanine (FePc) is conducted to reveal detailed influences of adsorbing sites, reaction energy, and electron behaviors of the C1 pathway. The screening shielding effect arising from the strong p-d coupling of the FeN binding is observed on the 2nd nearest neighboring site, thus, suppressing the neighboring effect. Meanwhile, two catalysts supported by graphene are fully investigated based on thermodynamic factors and the electron behaviors of graphene are interpreted.

However, natural recalcitrance and high pretreatment cost are major barriers to their complete conversion. In this study, a green processing method has been investigated for efficient recovery of natural pigments (anthocyanins), fermentable sugars, and pure lignin from Mxg genotypes using choline chloride-based natural deep eutectic solvents (NADES) systems. Interestingly, choline chloride: lactic acid (ChCl: LA) NADES-processed biomass resulted in 67.8 ± 2.1 μg g−1 of anthocyanins from dry biomass. A maximum of 87.4%–94.1% glucose yield was achieved after enzymatic saccharification. The effective extraction of lignin with high purity with higher β-aryl ether (βO4) bonds from advanced crops is crucial for lignin valorization. Notably, highly pure lignin (≈93.4% ± 1.4%) is achieved after low-temperature NADES pretreatment while retaining lignin's native structure. 31P nuclear magnetic resonance demonstrated that total phenolics for ChCl: LA-lignin resulted in 1.20 mmol g−1 hydroxyls.

This principle is exploited in salinity gradient power technologies like capacitive mixing (CapMix), where mixing occurs in a supercapacitor. Since this energy release holds true also for gases, research moves in the direction of harvesting energy from anthropic CO2. To do so, it is proposed for the first time to exploit an ionic liquid (IL), both as an electrolyte and CO2 absorbing medium in a CapMix cell. The mechanism consists in flowing a CO2-rich gas stream, alternated to a N2 stream, during the charging/discharging of two electrodes. The CO2 strongly affects the electrode/IL interface and the IL physicochemical properties thereby converting the released mixing energy into electrical energy. Unlike water-based systems, where energy harvesting relies on electric double-layer expansion, we propose a new mechanism based on electrochemical potential variations during CO2 capture/release, supported by molecular dynamics modeling. Key results include maximum voltage rise of 40 mV and energy and power densities of 40 μWh m−2 and 0.8 mW m−2. These findings clarify the mechanism behind the electrochemical phenomena occurring when CO2 interacts with IL and open the way to a new generation of electrochemical systems to harvest energy from CO2 emission.","PeriodicalId":29794,"journal":{"name":"Advanced Energy and Sustainability Research","volume":"6 6","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aesr.202500019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144255822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
