While multi-site catalysts provide a promising route to decouple complex reaction steps, the rational design and realization of architectures that enable rapid and directional inter-site intermediate spillover remains largely unexplored and highly challenging. Here, we report a strategy to program intermediate spillover and cascade catalysis in multielement dual-heterostructured catalysts through gradient adsorption potentials. Using the acidic oxygen evolution reaction as a model, a dual-heterostructured RuIr-Mo/WVOx catalyst is precisely engineered to integrate an oxyphilic WVOx matrix for rapid water dissociation, a Mo bridge for efficient *OHspillover, and a RuIr alloy for accelerated oxidation. Guided by first-principles screening and differences in elemental reducibility, a continuous gradient adsorption sequence (WVOx → Mo → RuIr) is constructed from a multielement architecture, enabling directional *OH transport across cooperatively coupled active centers with balanced energetics for cascade catalysis. As a result, the optimized catalyst delivers an overpotential of 183 mV at 10 mA cm- 2 and sustains stable operation for 450 h at 100 mA cm- 2, outperforming single-interface and commercial benchmarks. This work establishes gradient adsorption engineering as a general design framework for programming cascade catalysis in multistep reactions.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73229"},"PeriodicalIF":26.8,"publicationDate":"2026-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757895","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}

Using NiOx/SAM double HSLs, we found that the heteroatom-rich RA group with a carboxymethyl co-anchor enhances NiOx surface oxidation and provides strong interfacial passivation. DFT calculations, electrochemical analysis, and characterization via XPS, UPS, PL, and SEM were used to elucidate the HSL-perovskite interface relationship.

The optimized TPA-RA structure ensures balanced energetics and improved charge extraction, delivering an impressive indoor iPCE of 41.81% under a 1000 lux white LED.

The gradient micro-nano porous metafabric can broadly scatter the solar spectrum while establishing a gradual refractive index transition to enhance mid-infrared absorption. The solar reflectivity and infrared emissivity of the metafabric reached 99.7% and 93.3%, respectively, inducing a cooling effect of 10.2°C and net cooling power (Pnet) of 110.1 W/m2. Meanwhile, the metafabric with a gradual wettability gradient and capillary force gradient exhibited a high one-way transport index (R) of 1330.7% and a reverse breakthrough pressure of 15.0 cm H2O, effectively preventing liquid pinning and back penetration. What's more, the coupled strategy of thermal radiation, conduction, and evaporation resulted in a temperature drop of 20.2°C in the sweaty state.

Herein, we designed two multifunctional conjugated cationic ligands (TDZI and TzTzI) to modify the SAMs/perovskite interface. This study reveals that the conjugated ligands form tighter and ordered π-π stacking with [4-[(3,6-dimethyl-9H-carbazol-9-yl) butyl] phosphonic acid (Me-4PACz), efficiently suppressing Me-4PACz aggregation. Meanwhile, ligands dissolved in the perovskite precursor induce the bottom-up growth of 2D/3D heterojunction, which effectively regulates perovskite crystallization process and suppresses defect formation, thereby yielding high-quality and uniform perovskite films. These synergistic effects enhance the adhesion of SAM/perovskite interface, reduce interfacial non-radiative recombination loss, and accelerate the extraction and transport of carriers. Finally, the inverted PSCs modified with TzTzI achieved an exceptional power conversion efficiency (PCE) of 26.61% with a high open-circuit voltage (Voc) of 1.204 V, which is among the highest efficiencies reported to date for 2D/3D heterojunction PSCs.

While thermodynamic descriptors effectively rank catalysts within homologous families, they often fail to rationalize why fundamentally different material classes intrinsically favor distinct reaction pathways. Here, we identify local coordination geometry as a key structural factor that shapes this selectivity bifurcation. By establishing a general coordination-constraint framework, we show that extended surfaces stabilize intermediates through multi-atom coordination (ensemble effects). This imposes structural constraints on hydrogenation access to carbon or nitrogen centers while oxygen remains bound, thereby biasing reactions toward fully deoxygenated products (e.g., ethylene and ammonia). In contrast, the unilateral coordination of single-atom and molecular sites leaves the reactive center spatially exposed, enabling hydrogenation pathways to oxygen-retaining products (e.g., methanol and hydroxylamine) that are rarely accessible on close-packed surfaces. Importantly, this geometric effect operates in conjunction with electronic structure and interfacial factors. While coordination geometry defines the set of structurally accessible reaction pathways, electronic and electrochemical conditions govern their relative energetics and kinetic competition. This insight provides a transferable principle for the rational design of selective electrocatalysts.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e73223"},"PeriodicalIF":26.8,"publicationDate":"2026-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147757932","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}

In this study, we introduce a near-infrared (NIR)-controlled nanoscale proton delivery system using upconversion nanoparticles (UCNPs) coated with photoacid (PA) and ferrocene (Fc). Upon 980 nm NIR stimulation, UCNPs emit UV-visible emission (300-500 nm), activating surface-bound PA to induce transient H+ release and acidify the tumor microenvironment in vivo. This acute acidic stress reduces tumor cell glucose uptake by 50% and suppresses mechanistic target of rapamycin (mTOR) signaling, triggering excessive autophagy that functionally drives mitochondrial dysfunction and intrinsic apoptosis-a process we define as proton-mediated autophagy-induced apoptosis (PAA). Fc, a biodegradable peroxidase mimic and a non-fluorescent quencher, is incorporated to enable real-time visual quantification of proton accumulation via H+-triggered biodegradation, restoring the NIR upconversion luminescence (at 800 nm) of UCNPs. Following intravenous administration, the nanoagent achieves a six-fold reduction in tumor weight and elevates proton levels in glioma, effectively triggering PAA under non-invasive NIR irradiation.

These engineered junctions play a dual role: the localized electron-deficient sites strongly anchor and activate oxygen molecules, while the in-built polarity establishes directional channels for the migration of photogenerated charge carriers, ensuring their precise delivery to active sites.

However, its efficiency is fundamentally constrained by the piezoelectric screening effect, whereby accumulated free carriers rapidly neutralize polarization-induced charges, leading to short-lived internal fields and suppressed redox activity. Herein, ZnO nanoparticles are electrostatically integrated with a Zr-based metal-organic layer to construct a ZnO/Zr-MOL Z-scheme heterojunction that intrinsically mitigates this screening limitation. Interfacial coupling enables polarization-regulated band bending, spatially separating piezo-generated electrons and holes, and preventing their premature compensation by mobile carriers. The Z-scheme configuration preserves strong redox potentials while suppressing bulk and interfacial recombination, and the polarization-driven charge redistribution and dynamic realignment of the conduction and valence bands sustain the piezoelectric potential and markedly enhance carrier mobility and lifetime. Consequently, the optimized ZnO/Zr-MOL catalyst achieves an H2O2 production rate of 13.21 mm g-1 h-1 in pure water under ambient air conditions. When incorporated into an autonomous tidal-driven reactor, the heterostructure demonstrates strong environmental adaptability, achieving 74.5% degradation of Rhodamine B in 5 L of wastewater within 180 min.
