However, the low backbone planarity and the presence of bulky substituents adversely affect the crystallinity of NFREAs, impeding charge transport and the formation of bicontinuous morphology in organic solar cells. Here we show that a binary solvent system can individually control the crystallization and phase separation of the donor polymer (for example, D18) and the NFREA (for example, 2BTh-2F-C2). We select solvents such as chloroform and o-xylene that evaporate at different temperatures and rates and have different solubility for D18. Upon evaporation of chloroform, D18 starts to assemble into fibrils. Then, the evaporation of o-xylene induces the rapid formation of a fibril network that phase segregates 2BTh-2F-C2 into pure domains and leads to a bicontinuous morphology. The well-defined interpenetrating network morphology affords an efficiency of 19.02% on small-area cells and 17.28% on 1 cm2 devices.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":56.7,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The production and transport of green hydrogen itself is, however, not free from emissions. Here we assess the life-cycle greenhouse gas emissions for 1,025 planned green hydrogen facilities, covering different electrolyser technologies and renewable electricity sources in 72 countries. We demonstrate that the current exclusion of life-cycle emissions of renewables, component manufacturing and hydrogen leakage in regulations gives a false impression that green hydrogen can easily meet emission thresholds. Evaluating different hydrogen production configurations, we find median production emissions in the most optimistic configuration of 2.9 kg CO2 equivalents (CO2e) kg H2−1 (0.8–4.6 kgCO2e kg H2−1, 95% confidence interval). Including 1,000 km transport via pipeline or liquid hydrogen shipping adds another 1.5 or 1.8 kgCO2e kg H2−1, respectively. We conclude that achieving low-emission green hydrogen at scale requires well-chosen production configurations with substantial emission reductions along the supply chain.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":56.7,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we design and synthesize an asymmetric non-fullerene acceptor (Z8) featuring tethered phenyl groups to establish an alloy acceptor in ternary OSCs. The asymmetric structure minimizes non-radiative energy loss and charge recombination owing to delocalized excitons. The phenyl-substituted alkyl side chain impacts on the intermolecular interactions, improving the film nanomorphology with efficient exciton dissociation and reduced charge recombination. We demonstrate OSCs with an efficiency of 20.2% (certified 19.8%) based on the D18:Z8:L8-BO ternary blend. Through theoretical calculations, we examine the overall distribution of photon and carrier losses and analyse the potential for improvement on open-circuit voltage, short-circuit current density and fill factor, providing rational guidance for further development of the OSC performance. Molecular design is key to the power conversion efficiency in organic photovoltaics. Jiang, Sun, Xu et al. develop a non-fullerene acceptor with asymmetric structure and phenyl-substituted side chains that minimizes photon and carrier losses, enabling 20.2% efficiency.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141309133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, separation from two-dimensional pores has exploited differences in molecular mass or size. However, competitive sorption of CO2 with the potential to yield high permeance and selectivity has remained elusive. Here we show that a simple exposure of ammonia to oxidized single-layer graphene at room temperature incorporates pyridinic nitrogen at the pore edges. This leads to a highly competitive but quantitatively reversible binding of CO2 with the pore. An attractive combination of CO2/N2 separation factor (average of 53) and CO2 permeance (average of 10,420) from a stream containing 20 vol% CO2 is obtained. Separation factors above 1,000 are achieved for dilute (~1 vol%) CO2 stream, making the membrane promising for carbon capture from diverse point emission sources. Thanks to the uniform and scalable chemistry, high-performance centimetre-scale membranes are demonstrated. The scalable preparation of high-performance two-dimensional membranes opens new directions in membrane science. Graphene-based membranes are attractive for capturing CO2, with separation selectivity typically achieved by control of pore size. Here Hsu et al. incorporate pyridinic nitrogen species at the pore edges in graphene, leading to competitive CO2 binding and enhanced separation performance.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141304378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An alternative, photochemical, pathway powered by sunlight and operating under ambient conditions could potentially mitigate some of the associated greenhouse gas emissions. Here we report the photocatalytic dehydrogenation of ethane to ethylene and hydrogen using LaMn1−xCuxO3. This perovskite oxide possesses redox-active Lewis acid sites, comprising Mn(III) and Mn(IV), and Lewis base sites, comprising O(-II) and OH(-I), collectively dubbed surface-frustrated Lewis pairs. We find that tuning the relative proportions of these sites optimizes the activity, selectivity and yield for ethane dehydrogenation. The highest ethylene production rate and ethane conversion achieved were around 1.1 mmol g−1 h−1 and 4.9%, respectively. We show a simple outdoor prototype to demonstrate the viability of a solar ethylene process. In addition, techno-economic analysis revealed the economic potential of an industrial-scale solar ethylene production from ethane. Light-driven approaches could lower the carbon footprint of chemical production. Here the authors use the perovskite oxide LaMn1−xCuxO3 as a photocatalyst to convert ethane to ethylene and hydrogen.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141264759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
