  text: Self-templating is a facile strategy for synthesizing porous carbons by direct
    pyrolysis of organic metal salts. However, the method typically suffers from low
    yields (<4%) and limited specific surface areas (SSA<2000 m2 g−1) originating
    from low activity of metal cations (e.g., K+ or Na+) in promoting construction
    and activation of carbon frameworks. Here we use cesium acetate as the only precursor
    of oxo-carbons with large SSA of the order of 3000 m2 g−1, pore volume approaching
    2 cm3 g−1, tunable oxygen contents, and yields of up to 15 %. We unravel the role
    of Cs+ as an efficient promoter of framework formation, templating and etching
    agent, while acetates act as carbon/oxygen sources of carbonaceous frameworks.
    The oxo-carbons show record-high CO2 uptake of 8.71 mmol g−1 and an ultimate specific
    capacitance of 313 F g−1 in the supercapacitor. This study helps to understand
    and rationally tailor the materials design by a still rare organic solid-state
    chemistry.

  text: The electrical double‐layer plays a key role in important interfacial electrochemical
    processes from catalysis to energy storage and corrosion. Therefore, understanding
    its structure is crucial for the progress of sustainable technologies. We extract
    new physico‐chemical information on the capacitance and structure of the electrical
    double‐layer of platinum and gold nanoparticles at the molecular level, employing
    single nanoparticle electrochemistry. The charge storage ability of the solid/liquid
    interface is larger by one order‐of‐magnitude than predicted by the traditional
    mean‐field models of the double‐layer such as the Gouy–Chapman–Stern model. Performing
    molecular dynamics simulations, we investigate the possible relationship between
    the measured high capacitance and adsorption strength of the water adlayer formed
    at the metal surface. These insights may launch the active tuning of solid–solvent
    and solvent–solvent interactions as an innovative design strategy to transform
    energy technologies towards superior performance and sustainability.

  text: We report on the facile synthesis of porous carbons based on a biopolymer
    lignin employing a two-step process which includes the activation by KOH in various
    amounts under an inert gas atmosphere. The resulting carbons are characterized
    with regard to their structural properties and their electrochemical performance
    as an active material in double-layer capacitors using for the first time an ionic
    liquid (EMIBF4) as the electrolyte for this type of carbon material to enhance
    storage ability. A capacitance of more than 200 F g–1 at 10 A g–1 is achieved
    for a carbon with a specific surface area of more than 1800 m2 g–1. One of the
    most crucial factors determining the electrochemical response of the active materials
    was found to be the strong surface functionalization by oxygen-containing groups.
    Furthermore, the sulfur content of the carbon precursor lignin does not result
    in a significant amount of sulfur-containing surface functionalities which might
    interact with the electrolyte.
