Recent studies suggest that electron spin, when controlled at an electrode surface, can influence reaction pathways, but direct evidence linking spin effects to suppressed HER has been limited. Here we show that helical chiral copper (Cu) electrodes reduce competing HER during CO2 reduction, consistent with spin polarization induced via the chiral-induced spin selectivity effect. The helically structured Cu electrodes are fabricated by electrodeposition with a chiral templating reagent. Time-resolved Kerr ellipticity measurements, which track spin-polarized carriers generated by an ultrafast Seebeck current, confirm spin accumulation at the chiral Cu surface. This spin polarization disfavours H–H bond formation, thereby suppressing HER and enabling formate production alongside CO. These findings demonstrate that chirality-based spin control offers a strategy for steering selectivity in CO2 reduction and other reactions where HER is an undesired competitor. Electrocatalytic CO2 reduction is often hindered by the competing hydrogen evolution reaction, reducing selectivity for the desired products. Here the authors demonstrate that helical chiral copper electrodes can suppress hydrogen evolution by generating spin-polarized carriers through the chiral-induced spin selectivity effect.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 8","pages":"1151-1160"},"PeriodicalIF":70.1,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785298","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 identified that discontinuous SAM distribution causes shunting and a lower breakdown voltage, while indium tin oxide-triggered electrochemical deprotonation of formamidinium ions leads to reduced long-term stability under reverse-bias conditions. To address these issues, we developed a molecular-templated pre-assembly strategy driven by hydrogen-bonding interactions between the SAM and a polycarbazole template. This approach ensures homogeneous clusters in solution and strong substrate interactions, yielding dense and uniform layers. Subsequently, we prepared minimodules with 24.0% efficiency (certified steady-state efficiency of 23.2%) and improved reverse-bias stability. Small-area devices retained 95% efficiency after 300 h at −4.8 V, while minimodules exhibited a T98 lifetime of 312 h under negative open-circuit voltage stress. We showed that a single bypass diode can protect at least 16 subcells, setting a new reliability benchmark for scalable perovskite photovoltaics.

Meanwhile, more positive potentials compromise binding. Here we circumvent this trade-off using N-heterocyclic imines (NHIs), which exhibit a tailorable CO2 binding strength (~50–100 kJ mol−1 CO2) in the neutral state and release CO2 upon electro-oxidation, distinct from prevailing molecular capture mechanisms. Whereas initial NHI structures exhibited redox irreversibility due to solvent-based hydrogen abstraction, a phenylene-linked bis(NHI) design achieves redox reversibility by charge delocalization on the benzene ring, which simultaneously enables a 2 CO2 per e− swing. A symmetric electrochemically mediated CO2 capture system demonstrated stable cycling performance over 40 cycles and operated > 500 mV more positive than the oxygen reduction reaction, with projected theoretical minimum energy consumption of ~10 kJ mol−1 CO2 and a system work of 28–43 kJ mol−1 CO2 under 5–15% CO2. Electrochemically mediated CO2 capture typically makes use of sorbents that must be reduced before binding CO2, a process often hampered by competitive oxygen reduction reactions. Here the authors develop N-heterocyclic imines that capture CO2 in the neutral state and release it with near-theoretical Faradaic efficiency upon electro-oxidation, avoiding the competing reaction.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 8","pages":"1132-1140"},"PeriodicalIF":70.1,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785308","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 demonstrate that replacing GDC with mixed proton-, oxygen-ion- and hole-conducting BaCe1−xZrxO3-based materials (for example, BaCe0.7Zr0.1Y0.1Yb0.1O3−δ, BCZYYb7111) balances the electronic and ionic conductivity of the composite electrode, altering the reaction pathway to a lower-barrier rate-determining-step, and expanding the electrochemically active region to the entire electrode surface. In a configuration where the highly active misfit-layered Gd0.3Ca2.7Co3.82Cu0.18O9−δ catalyst is composited with BCZYYb7111, the reversible solid oxide cell achieves 7.08 W cm−2 in fuel-cell mode and –7.88 A cm−2 at 1.3 V in electrolysis mode using an yttria-stabilized zirconia electrolyte at 800 °C. This compositing strategy also enhances the performance of other popular oxygen electrocatalysts. Reversible solid oxide cells can be limited by the kinetics of the reactions occurring at the oxygen electrode.

Findings show that net-zero global power systems meeting universal electricity needs for decent living standards are technically feasible, requiring 15–20 TW of variable renewable energy (VRE). Abundant VRE resources offer cost-effective electricity access in low-income regions, such as Africa, promoting climate justice. Land use is critical, with solar photovoltaics alone requiring over 9 million hectares. Over 80% of VRE is within 200 km of load centres. Demand-side management could reduce system costs by 6.5% (∼US$182 billion yr−1). Expanding international transmission and removing renewable technology trade barriers could cut costs by 5.6% (∼US$157 billion yr−1) and 12.2% (∼US$345 billion yr−1), underscoring the pivotal role of international collaboration in building inclusive net-zero power systems.

However, conventional phosphoric acid-doped membranes must be relatively thick (typically >50 μm) to counteract H3PO4-induced mechanical degradation, leading to ohmic losses that limit fuel cell performance. Here we report a 20-μm-thin, mechanically robust phosphoric acid-doped membrane incorporating dynamic Cu-ion crosslinking for high-power-density high-temperature polymer electrolyte membrane fuel cells. The dynamic Cu-polymer coordination establishes dynamic crosslinking networks that provide exceptional toughness and extensibility, alongside spontaneous self-healing capability. Simultaneously, the Cu ions improve H3PO4 retention and proton dissociation through electrostatic interactions and polarization of O–H bonds in H3PO4 molecules. The resulting thin membranes exhibit minimal ohmic resistance (0.06 Ω cm2) while maintaining low H2 crossover current density (0.95 mA cm−2). Fuel cells incorporating this membrane achieved a peak power density of 3.08 W cm−2 at 200 °C (H2/O2), with negligible degradation over 503 h at 1.0 A cm−2 and 160 °C. High-temperature polymer electrolyte membrane fuel cells tend to use relatively thick membranes to counteract H3PO4-induced degradation, limiting performance.
