Obtaining multi-carbon products via CO2 photoreduction is a major catalytic challenge involving multielectron-mediated CC bond formation. Complex design of multicomponent interfaces that are exploited to achieve this chemical transformation, often leads untraceable deleterious changes in the interfacial environment affecting conversion efficiency and product selectivity. Alternatively, robust metal centers having asymmetric charge distribution can effectuate coupling reaction through stabilization intermediates, for desired However, generating inherent single component catalyst difficult material challenge. Here, novel photocatalyst, Bi19 S27 Cl3 , presented which selectively converts C2 product, ethanol, high yield under visible light irradiation. Structural analysis transmission electron microscopy, X-ray diffraction, photoelectron spectroscopy, absorption spectroscopy reveals presence polarized bismuth . The intrinsic electric field induced by renders better separation photogenerated electron-hole pair. Furthermore, adsorption CO* intermediate accelerate rate determining step formation OCCOH intermediate. Formation these intermediates experimentally mapped situ Fourier-transform infrared further confirmed theoretical calculation.

Components manipulation and structure engineering have shown powerful approaches for tailoring electromagnetic (EM) parameters. However, the integration of controllable architectural compositional complexity into one multiple‐layer heterostructure seems significantly effective but remains a considerable challenge, correlative quantized modulation EM parameters is scarce. Herein, three types metal–organic frameworks (MOFs) hybrids derived sulfides are ingeniously fabricated by MOF architecture solvothermal sulfuration. Compared to random assembly MOFs in “Chaotic” (Structure 1), regular arrangement MOF‐on‐MOF heterostructures “Matryoshka doll” 2) guarantees improved lattice strain defect arising from abundant heterointerfaces core–shell heterostructure. Impressively, such aforementioned advantages together with sufficiently exposed sites conductivity display an interesting “quantized state” between “0 “1 subsequent ion exchange process structured Zn–Co sulfides, benefiting “quantization” boost wave (EMW) absorption. Further, introducing metal ions cation‐doped 3) subtly optimizes composition defect, leading enhanced impedance matching absorption bandwidth 7.8 GHz at 2.6 mm. This study highlights significant effect on fluctuation, which synergy sulfur vacancy, tailor desirable EMW capacity.

The hollow sandwich core-shell micro-nanomaterials are widely used in materials, chemistry, and medicine, but their fabrication, particularly for transition metal phosphides (TMPs), remains a great challenge. Herein, general synthesis strategy is presented binary TMPs heterostructures with vertically interconnected nanosheets on the inside outside surfaces of polyhedron FeCoPx /C, demonstrated by variety metals (including Co, Fe, Cd, Mn, Cu, Cr, Ni). Density functional theory (DFT) calculation reveals process universal mechanism layered double hydroxide (LDH) growth Prussian blue analog (PBA) surface detail first time, which provides theoretical foundations feasibility rationality strategy. This unique structure exhibits vertical nanosheet-shell-vertical nanosheet configuration combining advantages sandwich, heterostructures, effectively achieving synergistic effect. As proof-of-concept applications, CoNiPx @FeCoPx /C@CoNiPx architectures (representative samples) show excellent catalytic performance oxygen evolution reaction (OER) alkaline electrolytes. work method constructing hollow-sandwich micro-nanostructures, more ideas directions design micro-nano materials special geometric topology.
