In recent years, green methanol and green ammonia, as important hydrogen carriers, have attracted wide attention because of their low carbon emission and high calorific value. However, ammonia has a slow laminar flame speed, and the addition of methanol can improve this characteristic. This has sparked interest in the study of ammonia/methanol co-combustion. This study first investigates the relationship between the methanol addition ratio, temperature, and the laminar flame speed of ammonia. Through MATLAB simulations, the study further examines the key species involved in the combustion process. The results indicate that the laminar flame speed is linearly related to the maximum concentration of (O + H + NH<small><sub>2</sub></small>). Following this, the yield and sensitivity analyses of the three radicals (O, H, and NH<small><sub>2</sub></small>) were performed. It was found that these three radicals have a positive correlation with both temperature and methanol content, with temperature and methanol primarily influencing the content of H radicals, which in turn affects O and NH<small><sub>2</sub></small>. Finally, using the modified fictitious diluent gas approach, it was concluded that the chemical properties of methanol are the main factor promoting ammonia oxidation.

The key findings are that (1) the energy transition from fossil fuel to low-carbon energy sources would reduce mining waste as well as the shipping carbon footprint; (2) the difference in capacity and actual electricity generation is significant for the life-cycle assessment due to low capacity factors of solar and wind energy; (3) several key metals with low abundance or high requirements dominate mining waste, which highlights the need for recycling and establishing a circular economy; (4) mining of critical minerals becomes important during the clean energy transition and (5) nuclear energy generates least waste and contributes least to shipping emissions among the low-carbon sources due to the high energy density and capacity factor and the small mass of materials it requires.

The stability of devices is directly associated with the stability of the perovskite ink and is linked with formulations that inhibit degradation reactions. In this work, we demonstrate how ammonium formate (AF) fulfills this objective and results in more stable devices and inks. We start with a conventional triple-cation perovskite ink and observe that elimination of methylamine (MA) from the formulation, and especially adding AF to the formulation, leads to remarkably durable inks. Optimized perovskite films containing AF exhibit a compact/low-pinhole morphology, with enhanced photoluminescence (PL) intensity and almost no degradation at 85 °C for 56 days, in contrast to AF-free films. Carbon-based perovskite cells with AF-doped perovskite films demonstrate improved efficiency (up to 19.40%) and perform considerably better in steady-state power output (SPO) tests and ISOS-D1 stability assessments. These come with high electroluminescence (EL) of the PSC devices and lower charge transfer resistance due to the AF additive.

Sodium metal anodes, with their abundant reserves, low cost, high specific capacity (1160 mA h g<small><sup>−1</sup></small>), and low redox potential (−2.714 V <em>vs.</em> the Standard Hydrogen Electrode (SHE)), are considered one of the most promising next-generation anode materials. However, the unstable solid electrolyte interphase (SEI) in sodium metal anodes leads to non-uniform diffusion and deposition of Na<small><sup>+</sup></small>, resulting in uncontrollable dendrite growth. During repeated charging/discharging processes, the growth of dendrites and the continuous fracture and regeneration of the SEI layer lead to the continuous loss of active sodium and coulombic efficiency (CE).

The rich amide groups in the organic component exert a polar attraction to Na<small><sup>+</sup></small>, regulating the Na<small><sup>+</sup></small> flux and alleviating the “tip effect” during metal deposition. Experiments show that the Na‖Na symmetric battery using this anode exhibits extremely low overpotential and stable plating/stripping behavior (cycling for over 2500 hours at 1 mA cm<small><sup>−2</sup></small> and 1 mA h cm<small><sup>−2</sup></small>, with an ultra-low voltage of 15 mV). The full cell assembled with Na<small><sub>3</sub></small>V<small><sub>2</sub></small>(PO<small><sub>4</sub></small>)<small><sub>3</sub></small> (NVP) demonstrates excellent rate and cycling performance, with a capacity retention rate of 90.3% after 1000 cycles at 1C and 89.2% after 800 cycles at a high rate of 5C.</p>","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 12","pages":" 3263-3270"},"PeriodicalIF":5.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144244065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
