Under high-voltage driving, the low symmetry and dangling bonds of these surface sites elevate the O 2p band center closer to the Fermi level, triggering premature electron extraction and irreversible gas evolution. Because these electron-rich surface oxygen species act as strong Lewis bases, quenching their excessive reactivity requires a localized charge-density countermeasure. Here, we introduce highly polarizable, large-radius cesium ions (Cs+) to construct a localized charge-shielding layer via specific cationic anchorage. Driven by ion–ion interactions, the highly diffuse electron clouds of Cs+ undergo charge polarization atop the dangling-bond oxygen sites, securely locking the surface electron density within the Mn–O framework. This polarization shield not only electrostatically arrests electron extraction from the lattice but also blocks solvent aggregation at the interface.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"11 10","pages":"6863–6871"},"PeriodicalIF":17.5,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010446","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 influence of local microenvironment on hydrogen spillover remains elusive, and strategies to deliberately regulate this phenomenon in photo-redox reactions are still in their infancy. Herein, we report the design of W-doped α-MoC1–x quantum dots anchored on a multifunctional graphene support, where the degree of graphene crystallization can be precisely modulated. Our findings reveal that hydrogen spillover can be effectively orchestrated by tailoring the local environment particularly in the presence of free H2O and surface hydroxyl groups, resulting in over a 20-fold enhancement in photocatalytic hydrogen evolution compared to bare ZnIn2S4. Furthermore, an ordered graphene arrangement facilitates continuous hydrogen spillover and maintains hydroxyl dynamic equilibrium, significantly boosting the photocatalytic stability. This work highlights the critical role of mass transfer in photocatalysis. These insights open new avenues for advancing photocatalysis research through microenvironment engineering.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"11 10","pages":"6745–6754"},"PeriodicalIF":17.5,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149049853","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 investigate the role of the methylammonium thiocyanate (MASCN) additive in quasi-2D PSCs. XRD, GIWAXS, and transient absorption spectroscopy show that SCN– suppresses the formation of low-n phases and promotes higher-n domains. Spectroscopy and scattering measurements reveal that SCN– coordinates Pb2+ to form intermediate iodoplumbate complexes that appear to assemble into large precursor aggregates, consistent with nucleation intermediates likely promoting higher-n phases. This structural reconfiguration enhances the power conversion efficiency from 5.8 to 13.4%, and retains ∼75% of their initial efficiency after 1000 h under maximum power point tracking and in N2 atmosphere, despite the reduced fraction of the inherently stable low-n phases. These findings demonstrate that the control of the nucleation at the precursor stage is an effective strategy to tune phase distribution and improve efficiency without severely compromising stability in quasi-2D PSCs.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"11 10","pages":"6872–6880"},"PeriodicalIF":17.5,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148908741","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}

Conventional P2/O3 biphasic strategies to boost capacity typically sacrifice structural stability or median voltage. In this work, density functional theory calculations identify the thermodynamic phase-ratio boundary for biphasic stability, confirming that limiting sodium-rich O3 phase below 20% suppresses the detrimental O3-P3 transition during cycling. Guided by this, precise transition metal tuning yields an optimal atomically intermixed P2/O3-93 cathode (Na3/4Ni1/3Fe1/12Mn7/12O2). It exhibits pronounced zero-strain behavior, with volume change reduced from 3.7% (O3-type reference) to <1%.
