Comprehensive structural characterization is performed to obtain a high‐fidelity crystal structure of H 2 W 2 O 7 using an iterative approach that combines X‐ray diffraction, neutron pair distribution function, scanning transmission electron microscopy, Raman spectroscopy, and density functional theory modeling. Electrochemical characterization shows a capacity retention of ≈80% at 1000 mV s –1 (1.5‐s charge/discharge time) as compared to 1 mV s –1 (≈16‐min charge/discharge time) with cyclability for over 100 000 cycles. Energetics from density functional theory calculations indicate that proton storage occurs at the terminal oxygen sites within the hydrated interlayer. Last, optical micrographs collected during in situ Raman spectroscopy show reversible, multicolor electrochromism, with color changes from pale yellow to blue, purple, and last, orange as a function of proton content. These results highlight the use of selective etching of layered perovskites for the synthesis of metastable transition metal oxide materials and the use of H 2 W 2 O 7 as an anode material for proton‐based energy storage or electrochromic applications.}, number={1}, journal={ADVANCED ENERGY MATERIALS}, author={Wang, Ruocun and Sun, Yangyunli and Brady, Alexander and Fleischmann, Simon and Eldred, Tim B. and Gao, Wenpei and Wang, Hsiu-Wen and Jiang, De-en and Augustyn, Veronica}, year={2021}, month={Jan} }

The triple-hybrid core/shell material was prepared by atomic layer deposition of molybdenum oxide onto carbon nanotube networks, followed by annealing in a sulfur-containing gas atmosphere. High-resolution transmission electron microscopy together with electron diffraction, supported by chemical analysis via energy dispersive X-ray and electron energy loss spectroscopy, gave proof of a MoO2 core covered by few layers of a MoS2 shell within an entangled network of carbon nanotubes. To gain further insights into this complex material, the analysis was completed with 3D electron tomography. By using Z-contrast imaging, distinct reconstruction of core and shell material was possible, enabling the analysis of the 3D structure of the material. These investigations showed imperfections in the nanoparticles which can impact material performance, i.e. for faradaic charge storage or electrocatalysis.}, number={4}, journal={NANOSCALE ADVANCES}, author={Frank, Anna and Gaensler, Thomas and Hieke, Stefan and Fleischmann, Simon and Husmann, Samantha and Presser, Volker and Scheu, Christina}, year={2021}, month={Feb}, pages={1067–1076} }

Many theoretical and computational studies have shown that the confinement of liquid-phase reactants to nano- or subnanometer spaces influences their electrochemical reactivity. While confinement is ubiquitous in various high surface area materials used as electrodes, experimental studies of this effect are scarce due to the challenge of deconvoluting the many competing influences on the measured electrochemical signal. This creates an exciting opportunity for the synthesis of well-defined materials platforms capable of confining liquid electrolytes and reactants for understanding electrochemical reactivity under confinement. In particular, a precise confinement geometry can be achieved with the use of 2D and layered materials whose interlayers have been tuned with the use of molecular pillars.}, number={8}, journal={CHEMISTRY OF MATERIALS}, author={Fleischmann, Simon and Spencer, Michael A. and Augustyn, Veronica}, year={2020}, month={Apr}, pages={3325–3334} }

One strategy to achieve this goal is with pseudocapacitive materials that take advantage of reversible surface or near-surface Faradaic reactions to store charge. This allows them to surpass the capacity limitations of electrical double-layer capacitors and the mass transfer limitations of batteries. The past decade has seen tremendous growth in the understanding of pseudocapacitance as well as materials that exhibit this phenomenon. The purpose of this Review is to examine the fundamental development of the concept of pseudocapacitance and how it came to prominence in electrochemical energy storage as well as to describe new classes of materials whose electrochemical energy storage behavior can be described as pseudocapacitive.}, number={14}, journal={CHEMICAL REVIEWS}, author={Fleischmann, Simon and Mitchell, James B. and Wang, Ruocun and Zhan, Cheng and Jiang, De-en and Presser, Volker and Augustyn, Veronica}, year={2020}, month={Jul}, pages={6738–6782} }
