MXene-functionalised 3D-printed electrodes for electrochemical capacitors

3D printing is a manufacturing technique that can be used to produce electrochemical capacitors with customised shapes and minimal material waste. However, the range of carbon-additive filaments currently commercially available is limited, resulting in 3D-printed electrodes with a poor capacitive performance due to their high thermoplastic content. Herein, a novel approach is presented for enhancing …

Synthesis of Carboxylated-Graphenes by the Kolbe-Schmitt Process

Graphene oxide is an oxidized form of graphene containing a large variety of oxygen groups. Although past models have suggested carboxylic acids to be present in significant amounts, recent evidence has shown otherwise. Toward the production of carboxyl-graphene, a synthetic method is presented herein based on the Kolbe- Schmitt process. A modified procedure of heating …

Dichlorocarbene-Functionalized Fluorographene: Synthesis and Reaction Mechanism

Halogen functionalization of graphene is an important branch of graphene research as it provides opportunities to tailor the band gap and catalytic properties of graphene. Monovalent C-X bond obviates pitfalls of functionalization with atoms of groups 13, 15, and 16, which can introduce various poorly defined groups. Here, the preparation of functionalized graphene containing both …
