However, trace SO2 in common flue gases rapidly and irreversibly poisons catalysts. Here we report that limiting hydrogen adsorption in the vicinity of electrochemically active sites deactivates SO2 to enable efficient CO2 conversion. We realize this approach via a polymer/catalyst/ionomer heterojunction design with combined hydrophobic and highly charged hydrophilic domains that diminish hydrogen adsorption and promote CO2 over SO2 transport. We develop an SO2-tolerant system that maintains ~50% faradaic efficiency towards multi-carbon products for over 150 h (at 100 mA cm–2). Extending this strategy to a high-surface-area composite catalyst, we achieve faradaic efficiencies of 84%, partial current densities of up to 790 mA cm–2 and energy efficiencies of ~25% towards multi-carbon products with a CO2 stream containing 400 ppm SO2, a performance that is competitive with the best reports using pure CO2. While the high concentration of CO2 in flue gas makes it an attractive feedstock for electrocatalytic production of useful molecules, SO2 contaminants can poison catalysts. Here the authors report a polymer/catalyst/ionomer heterojunction design with hydrophobic and hydrophilic domains that improves the SO2 tolerance of a Cu catalyst.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141546207","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}

However, their implementation has been limited by unstable anode morphological changes and anode–liquid electrolyte interface reactions. Here we show that an electrochemically stable solid electrolyte and the application of stack pressure can solve these issues by enabling the deposition of dense sodium metal. Furthermore, an aluminium current collector is found to achieve intimate solid–solid contact with the solid electrolyte, which allows highly reversible sodium plating and stripping at both high areal capacities and current densities, previously unobtainable with conventional aluminium foil. A sodium anode-free all-solid-state battery full cell is demonstrated with stable cycling for several hundred cycles. This cell architecture serves as a future direction for other battery chemistries to enable low-cost, high-energy-density and fast-charging batteries. Anode-free batteries are cost effective but limited by unstable anode morphology and interface reactions. Here the authors discuss design parameters and construct an anode-free sodium solid-state battery using compressed aluminium particles as the anode current collector to improve cycling performance.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141496034","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 characterize the long-distance travel pattern in England and explore its importance on carbon emissions from and decarbonization of passenger travel. We find that only 2.7% of a person’s trips are for long distance travel (>50 miles one-way), but they account for 61.3% of the miles and 69.3% of the greenhouse gas (CO2 equivalent) emissions from passenger travel, highlighting its importance for decarbonizing passenger transport. Long-distance travel per person has also been increasing over time, trending in the opposite direction to shorter-distance travel. Flying for leisure and social purposes are the largest contributors to long distance miles and emissions, and these miles are also increasing. Overall, per capita travel emissions have started decreasing slowly from 2007, but are still higher than in 1997. We propose a new metric—emissions reduction sensitivity (% emission reduced/% trips altered)—to understand the efficiency of travel demand related initiatives to reduce greenhouse gas emissions. Long-distance travel—especially flying—can offer orders of magnitude larger emissions reduction sensitivity compared with urban travel, which suggests that a proportionate policy approach is necessary. Decarbonization of transport is critical for emissions reduction goals, but understanding long-distance passenger travel patterns remains difficult. This study combines different travel surveys in England to explore long-distance travel and its oversized impact on emissions, proposing a new metric to examine decarbonization potential.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-024-01561-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141489102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, PSCs have poor reverse-bias stability that limits their real-world application. Here we report a systematic study on the degradation mechanisms of p–i–n structure PSCs under reverse bias. The oxidation of iodide by injected holes at the cathode side initialize the reverse-bias-induced degradation, then the generated neutral iodine oxidizes metal electrode such as copper, followed by drift of Cu+ into perovskites and its reduction by injected electrons, resulting in localized metallic filaments and thus device breakdown. A reinforced barrier with combined lithium fluoride, tin oxide and indium tin oxide at the cathode side reduces device dark current and avoids the corrosion of Cu0. It dramatically increases breakdown voltage to above −20 V and improved the T90 lifetime of PSCs to ~1,000 h under –1.6 V. The modified minimodule also maintained over 90% of its initial performance after 720 h of shadow tests. The stability of perovskite photovoltaics under reverse bias is limited and thus an issue for real-world applications. Nengxu Li and colleagues report the underlying degradation mechanism at the cathode side and a multilayer barrier to minimize it.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141475322","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}

However, the share of non-fossil sources in China’s urban district heating systems remain low, and many new coal-fired combined heat and power plants are being built. Strategic choices for district heating technologies are necessary for China to reach peak carbon emissions by 2030 and achieve carbon neutrality by 2060. Here we find that replacing polluting coal technologies with new and improved coal-fired combined heat and power plants will lead to substantial carbon lock-in and hinder decommissioning of associated coal-fired electricity generation. Expanding the use of industrial waste heat and air/ground-source heat pumps can avoid the need for new combined heat and power construction and reduce carbon emissions by 26% from 2020 to 2030. Our findings indicate the importance of the government’s recent proposals to decarbonize district heating. China’s continuing reliance on coal in district heating risks considerable carbon lock-in and hinders decommissioning of coal-fired electricity generation. This work outlines how the government can achieve its proposal to decarbonize district heating.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141475306","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}
