Title: Bridging Structural and Chemical Insights: Integrating In Situ Electron Microscopy and X-ray Spectroscopy for Catalysis Research
Environmental transmission electron microscopy probes the local structure, composition, and chemistry of materials under gas environments, while ambient-pressure X-ray photoelectron spectroscopy provides ensemble chemical and electronic structure information in gaseous conditions. Both techniques utilize similar differential pumping schemes to mitigate electron scattering by the gas phase, allowing for unique opportunities to correlate gas–surface interactions across comparable pressure ranges. Their integration has advanced the understanding of various catalytic reactions, including the water–gas-shift reaction, CO oxidation, and surface passivation dynamics. This Mini-Review discusses their methodological advancements, challenges, and potential for further integration with other in situ techniques to address complex catalytic phenomena and guide catalyst design.  more » « less

    Abstract Ferroelectrics, due to their polar nature and reversible switching, can be used to dynamically control surface chemistry for catalysis, chemical switching, and other applications such as water splitting. However, this is a complex phenomenon where ferroelectric domain orientation and switching are intimately linked to surface charges. In this work, the temperature‐induced domain behavior of ferroelectric‐ferroelastic domains in free‐standing BaTiO3films under different gas environments, including vacuum and oxygen‐rich, is studied by in situ scanning transmission electron microscopy (STEM). An automated pathway to statistically disentangle and detect domain structure transformations using deep autoencoders, providing a pathway towards real‐time analysis is also established. These results show a clear difference in the temperature at which phase transition occurs and the domain behavior between various environments, with a peculiar domain reconfiguration at low temperatures, from a‐c to a‐a at ≈60 °C. The vacuum environment exhibits a rich domain structure, while under the oxidizing environment, the domain structure is largely suppressed. The direct visualization provided by in situ gas and heating STEM allows to investigate the influence of external variables such as gas, pressure, and temperature, on oxide surfaces in a dynamic manner, providing invaluable insights into the intricate surface‐screening mechanisms in ferroelectrics.

    The atomic-scale structure of a metal catalyst surface controls its catalytic performance. Through a combination of High-pressure Scanning Tunneling Microscopy (HP-STM), Ambient Pressure X-ray Photoelectron Spectroscopy (AP-XPS) and machine learning-accelerated computational studies we uncovered that Pt nanoclusters, formed by restructuring of hex-Pt(100) under reaction conditions involving CO, experience major structural evolution when exposed to increasing CO pressure in the range of 210-8–750 Torr. Atom-resolved images and simulations demonstrate that CO binds strongly on these nanoclusters, leading to a CO coverage of one molecule per Pt atom while the lateral CO-CO repulsion is released by tilting CO molecules outward at the nanocluster edge. Metal nanoclusters break down along as CO pressure is increased from 210-8 to 1 Torr with the average size decreasing from 3.21.5 nm to 2.31.0 nm, consistent with Pt 4f7/2 photoemission feature evolution observed with AP-XPS. In contrast, in the pressure range of 1-750 Torr at 25oC, HP-STM observed a decrease of nanocluster density by 4-5 times, consistent with a growth of the average nanocluster size from 2.31.0 nm in 1 Torr CO to 4.61.8 nm in 750 Torr. This uncovers a reactant pressure-driven coalescence of nanoclusters even at room temperature. Nanoclusters formed at 25oC in 750 Torr CO require annealing to 100-130oC to reach equilibrium size, indicating kinetic control of nanocluster growth at low preparation temperatures. Our neural network potential (NNP) coupled with basin hoping (BH) simulations determined the optimal CO coverage and configuration at various CO pressures and showed, in agreement with experiments, an optimum nanocluster size resulting from a competition between the size-dependent energy cost of nanocluster formation and the energy gain through CO adsorption. The formation of Pt nanoclusters, followed by their breakdown with increasing CO pressure from 210-8 to 1 Torr and coalescence in CO pressure from 1 Torr to 750 Torr highlights the significance of imaging catalyst nanoparticle surfaces in gas phase at a specific reactant pressure towards establishing a direct structure-catalytic performance correlation.

    Exciting progress has been made in the area of solar fuel generation by CO 2 reduction. New photocatalytic materials containing well-defined surface catalytic sites have emerged in recent years, including heterogenized molecular catalysts and single atom catalysts. This Feature Article summarizes our recent research in this area, together with brief discussions of relevant literature. In our effort to obtain heterogenized molecular catalysts, a diimine-tricarbonyl Re( i ) complex and a tetraaza macrocyclic Co( iii ) compound were covalently attached to different surfaces, and the effects of ligand derivatization and surface characteristics on their structures and photocatalytic activities were investigated. Single atom catalysts combine the advantages of homogeneous and heterogeneous catalysis. A single-site cobalt catalyst was prepared on graphitic carbon nitride, which demonstrated excellent activity in selective CO 2 reduction under visible-light irradiation. Doping carbon nitride with carbon was found to have profound effects on the structure and activity of the single-site cobalt catalyst. Our research achievements are presented to emphasize how spectroscopic techniques, including infrared, UV-visible, electron paramagnetic resonance, and X-ray absorption spectroscopies, could be combined with catalyst synthesis and computation modeling to understand the structures and properties of well-defined surface catalytic sites at the molecular level. This article also highlights challenges and opportunities in the broad context of solar CO 2 reduction.

    We reproduce the consistently-seen experimental voltage vs pressure (V–p) dependence of DC magnetron sputtering with two-dimensional-RZ particle-in-cell (PIC) simulation. Informed by PIC simulation, we develop a steady-state, 1D-axial fluid model of the sheath and presheath that also reproduces this V–p dependence. The V–p dependence is the relationship between the steady-state voltage needed to maintain a constant discharge current and the neutral gas pressure. V–p dependence is fundamental to device performance, but has not previously been reproduced with simulation or satisfactorily explained. We find that the decrease in voltage with increasing pressure is not due to electron recapture at the cathode. Rather, the constant current dictates a constant global ionization rate, so the voltage decrease compensates for the increase in neutral gas density by lowering the energy of the plasma electrons, which decreases their ionization probability. The PIC simulations also reveal that the presheath and bulk plasma are unaffected by the electron reflection coefficient at the cathode; the only effect of increasing reflection is a reduction in the sheath voltage and width. In addition to the potential structure, we explore how pressure affects the plasma density, particle drifts, and particle energy distributions.

    Abstract Based on historical developments and the current state of the art in gas-phase transmission electron microscopy (GP-TEM), we provide a perspective covering exciting new technologies and methodologies of relevance for chemical and surface sciences. Considering thermal and photochemical reaction environments, we emphasize the benefit of implementing gas cells, quantitative TEM approaches using sensitive detection for structured electron illumination (in space and time) and data denoising, optical excitation, and data mining using autonomous machine learning techniques. These emerging advances open new ways to accelerate discoveries in chemical and surface sciences. Graphical abstract
