Invited for this month's cover is the group of Tom Rufford at the University of Queensland. The image shows how choline chloride and urea in a reline solution interact with the surface of a silver cathode to enhance the selectivity of electrochemical CO reduction to CO. The Full Paper itself is available at 10.1002/cssc.201902433.

Anode-free all solid-state batteries (AF-ASSBs) employ "empty" current collector with three active interfaces that determine electrochemical stability; lithium metal - Solid electrolyte (SE) interphase (SEI-1), lithium - current collector interface, and collector - SE interphase (SEI-2). Argyrodite LiPSCl (LPSCl) solid electrolyte (SE) displays SEI-2 containing copper sulfides, formed even at open circuit. Bilayer of 140 nm magnesium/30 nm tungsten (Mg/W-Cu) controls the three interfaces and allows for state-of-the-art electrochemical performance in half-cells and fullcells.

Electrocatalytic nitrate reduction reaction (NORR) to harmless nitrogen (N) presents a viable approach for purifying NO-contaminated wastewater, yet most current electrocatalysts predominantly produce ammonium/ammonia (NH/NH) due to challenges in facilitating N-N coupling. This study focuses on identifying metal catalysts that preferentially generate N and elucidating the mechanistic origins of their high selectivity. Our evaluation of 16 commercially available metals reveals that only Pb, Sn, and In demonstrated substantial N selectivity (79.

Renewable energy-driven electrochemical CO2 reduction has emerged as a promising technology for a sustainable future. However, achieving efficient production of storable liquid fuels at ampere-level current densities remains a significant hurdle in the large-scale implementation of CO2 electroreduction. Here we report a novel catalytic electrode comprising chlorine-doped SnO2 nanoflowers arrayed on the exterior of three-dimensional nickel hollow fibers.

Single-atom catalysts (SACs) have become the forefront and hotspot in energy storage and conversion research, inheriting the advantages of both homogeneous and heterogeneous catalysts. In particular, carbon-supported SACs (CS-SACs) are excellent candidates for many energy storage and conversion applications, due to their maximum atomic efficiency, unique electronic and coordination structures, and beneficial synergistic effects between active catalytic sites and carbon substrates. In this review, we briefly review the atomic-level regulation strategies for optimizing CS-SACs for energy storage and conversion, including coordination structure control, nonmetallic elemental doping, axial coordination design, and polymetallic active site construction.

Electrochemical reduction of CO is an efficient strategy for CO utilization under mild conditions. Tin (Sn) single-atom catalysts (SACs) are promising candidates due to their controllable CO/formate generation via asymmetric coordination engineering. Nevertheless, the factors that govern the selectivity remain unclear.
