Herein, we utilized a pH-field coupled microkinetic model to identify Fe1Co1–N6 as the optimal dual-atom catalyst (DAC) for ORR in alkaline media. According to theoretical prediction, a Fe1Co1–N–C DAC with a hierarchically porous structure was synthesized by a hard-template method following a CO2 activation process. The prepared Fe1Co1–N–C DAC exhibits superior ORR activity and stability to the benchmark Pt/C catalyst. More impressively, the Fe1Co1–N–C based ZABs exhibit excellent performance including a high open-circuit voltage (1.51 V), a very high energy density (1079 W h kgZn−1), the best-ever rate capability (from 2 to 600 mA cm−2), and ultra-long ZAB lifespan (over 3600 h/7200 cycles under 5 mA cm−2).

For instance, the presence of chloride ions (Cl−) hinders the desired oxygen evolution reaction (OER) because competing chlorine evolution reactions (CER) occur and adversely impact electrode materials, resulting in low system efficiency and poor longevity. To enhance long-term stability of DSE, researchers are investigating robust electrocatalysts and advanced surface modifications that improve protection against corrosive environments and enhance selectivity. Innovative electrode designs are also being developed to manage bubble transport and decrease precipitation. Additionally, the design of electrolysis cells, such as bipolar membrane cells, offers a viable solution by minimizing Cl− transport and corrosive environment.

The unique coordination of FeN3 sites with PtCo intermetallic enables precise optimization of catalyst size and structure, boosting PtCo intermetallic activity and yielding exceptional ORR performance. This is verified by a half-wave potential of 0.86 V vs. RHE in 0.5 M H2SO4 and a mass activity of 1.34 A/mgPt, achieving an 8.1-fold improvement over Pt/C, while maintaining exceptional durability for over 50,000-cycles. In-situ characterization and theoretical calculations reveal that isolated Fe sites reduce the d-band center of neighboring Pt sites, weakening adsorption energy and synergistically enhancing both activity and stability. When deployed in the air cathode of a hybrid acid/alkali Zn-air battery, the catalyst delivers an outstanding open circuit voltage of 2.32 V and a peak power density of 751 mW cm-2.

However, the mismatched crystallization rate between the donor and acceptor often leads to the difficulties in realizing desirable morphology, further resulting in non-radiative recombination energy loss (ΔEnon-rad). Herein, a series of halogenated volatile additives of 1-fluoro-3,5-dimethoxybenzene (F-DMB), 1-chloro-3,5-dimethoxybenzene (Cl-DMB), 1-bromo-3,5-dimethoxybenzene (Br-DMB) and 1-iodo-3,5-dimethoxybenzene (I-DMB) have been designed to optimize the interaction with donor and acceptor, thereby regulating the crystallization kinetics, improving morphology quality and reducing ΔEnon-rad. As the weight of halogen atom of additive increased, the promoting effect on PM6 strengthened gradually, thus shortening the crystallization time. However, such promoting effect on L8-BO was weakened, resulting in a longer crystallization time. Therefore, this strategy made the crystallization time ratio approach to unity with a more balanced crystallization behavior. Due to the well-regulated crystallization kinetics and optimized intermolecular aggregation, the optimal morphology with suppressed energy disorder and ΔEnon-rad were realized. The I-DMB-treated PSCs achieved the champion power conversion efficiency (PCE) of 20.40% and minimized ΔEnon-rad of 0.189 eV.

Regarding this, one of the most impactful developments is the application of hole-selective self-assembled monolayers (SAMs), leading to the advancement in APTSC technology. However, SAMs with poor polar-solvent resistance would be inevitably delaminated from substrates during perovskite precursor coating, remaining great challenge in achieving a complete SAMs coverage with derivatization issues, e.g. defective perovskite and considerable interface energy loss. Here, we introduced an in-situ molecular compensation strategy to address the inherent flaw of SAMs within WBG perovskites via incorporating 5-ammonium valeric acid iodide (5-AVAI). The larger-dipole 5-AVAI spontaneously accumulates toward the buried interface to compensate the SAMs-deficient sites when depositing WBG perovskite, effectively minimizing interfacial energy loss. Simultaneously, amphoteric 5-AVAI with amino and carboxyl groups can compensate the defects at grain boundaries for solid passivation. Consequently, a champion efficiency of 20.23% with a record VOC of 1.376 V was realized on WBG devices, enabling an efficiency of 28.9% for the APTSCs. Encouragingly, the tandems showed good operational stability and retained 87.3% of their efficiency after 800 hours of tracking.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"42 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876349","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 provide new insights into structure-performance relationship in hard carbon by coupling key structural parameters based on integrating theoretical computations and experimental data. Density functional theory calculations show that interlayer spacing determines diffusion behavior of sodium ions in hard carbon, while appropriate defect and curvature secure high-quality intercalation capacity. Inspired by these theoretical results, we successfully produce high-performance hard carbon with optimal microstructures through in-situ molecular reconfiguration of biomass via thermodynamically-driven approach, which is demonstrated as an effective strategy to rationally regulate the microstructure of hard carbon by comprehensive physical characterizations from macroscopic to atomic level.

Here, we report a multi-tentacle electrolyte (MTE) strategy that enables stable, fast and deep running of AZBs at −40 °C. MTE leverages the abundant hydrogen-bonding sites of multi-tentacle salts and organics. Adding small amounts of multi-tentacle moieties not only effectively confines water molecules’ movement and prevents their icing even at −60 °C, but also maintains low viscosity and high ionic conductivity of the electrolyte at low temperatures. At −40 °C, Zn metal anodes could stably cycle for more than 1100 hours at a high current density of 2 mA cm−2 and a high capacity of 2 mAh cm−2; high-capacity AZBs (3.4 mAh cm−2) sustain 1000 stable cycling with 99.99% retention per cycle in MTE.
