    Abstract In this work, we present a novel artificial photosynthetic paradigm with square meter (m 2 ) level scalable production by integrating photovoltaic electrolytic water splitting device and solar heating CO 2 hydrogenation device, successfully achieving the synergy of 1 sun driven 19.4% solar to chemical energy efficiency (STC) for CO production (2.7 times higher than that of large-sized artificial photosynthetic systems) with a low cost (equivalent to 1/7 of reported artificial photosynthetic systems). Furthermore, the outdoor artificial photosynthetic demonstration with <sc>1.268 m 2 </sc> of scale exhibits the CO generation amount of <sc>258.4 L</sc> per day, the STC of ~15.5% for CO production in winter, which could recover the cost within 833 sunny days of operation by selling CO.

    Abstract The interfacial pyro-phototronic effect (IPPE) presents a novel approach for improving the performance of self-powered photodetectors (PDs) based on metal halide perovskites (MHPs). The interfacial contact conditions within the Schottky junctions are crucial in facilitating the IPPE phenomenon. However, the fabrication of an ideal Schottky junction utilizing MHPs is a challenging endeavor. In this study, we present a surface passivation method aimed at enhancing the performance of self-powered photodetectors based on inverted planar perovskite structures in micro- and nanoscale metal-halide perovskite SCs. Our findings demonstrate that the incorporation of a lead halide salt with a benzene ring moiety for surface passivation leads to a substantial improvement in photoresponses by means of the IPPE. Conversely, the inclusion of an alkane chain in the salt impedes the IPPE. The underlying mechanism can be elucidated through an examination of the band structure, particularly the work function (WF) modulated by surface passivation. Consequently, this alteration affects the band bending and the built-in field (

    Abstract Knowledge of deformation mechanisms in aragonite, one of the three crystalline polymorphs of CaCO3, is essential to understand the overall excellent mechanical performance of nacres. Dislocation slip and deformation twinning were claimed previously as plasticity carriers in aragonite, but crystallographic features of dislocations and twins have been poorly understood. Here, utilizing various transmission electron microscopy techniques, we reveal the atomic structures of twins, partial dislocations, and associated stacking faults. Combining a topological model and density functional theory calculations, we identify complete twin elements, characters of twinning disconnection, and the corresponding twin shear angle (∼8.8°) and rationalize unique partial dislocations as well. Additionally, we reveal an unreported potential energy dissipation mode within aragonite, namely, the formation of nanograins via the pile-up of partial dislocations. Based on the microstructural comparisons of biogenic and abiotic aragonite, we find that the crystallographic features of twins are the same. However, the twin density is much lower in abiotic aragonite due to the vastly different crystallization conditions, which in turn are likely due to the absence of organics, high temperature and pressure differences, the variation in inorganic impurities, or a combination thereof. Our findings enrich the knowledge of intrinsic crystal defects that accommodate plastic deformation in aragonite and provide insights into designing bioengineering materials with better strength and toughness.

    Abstract Metal single atoms show outstanding electrocatalytic activity owing to the abundant atomic reactive sites and superior stability. However, the preparation of single atoms suffers from inexorable metal aggregation which is harmful to electrocatalytic activity. Here, ionic covalent organic frameworks (iCOFs) are employed as the sacrificial precursor to mitigate the metal aggregation and subsequent formation of bulky particles. Molecular dynamics simulation shows that iCOFs can trap and confine more Co ions as compared to neutral COFs, resulting in the formation of a catalyst composed of Co single atoms and uniformly distributed Co nanoparticles (Co

    Abstract Hydrogen generation from water-gas shift (WGS) reaction requires the import of secondary energy, making it unsuitable for large scale applications. Herein, we present a new scalable system consisting of new photothermal device and catalysts that can produce hydrogen via the WGS reaction with zero additional energy import. The new photothermal device based on a chromium film can completely absorb sunlight, fully convert sunlight to heat energy and localize the heat energy synergistically, which makes a high temperature of 305 °C under one standard sunlight irradiation. The catalysts are scalable CuOₓ/ZnO/Al₂O₃ nanosheets (2D CuZnAl) with high WGS activity, which were synthesized via the surfactant effect of boric acid. The 2D CuZnAl could be heated to 297 °C under one standard solar irradiation with the new photothermal device. This new system shows a hydrogen production rate of 192.33 mmol g⁻¹ h⁻¹ under one standard sunlight irradiation, 402 times to that of the current record of the one sunlight-driven WGS reaction. Moreover, this new system could be amplified to industrial scale with 4.2 m² of irradiated area and was able to generate 6.60 m³ of hydrogen from the WGS reaction solely driven by outdoor sunlight in the daytime of spring as well as realized a zero emission of CO₂ with the help of a greenhouse agriculture. This study introduces a scalable, highly efficient zero CO₂ emission and stable route of outdoor sunlight-driven hydrogen generation from the WGS reaction.
