The need to deliver high performant and miniaturised electrochemical sensors has boosted the use of carbon nanomaterials as smart modifiers of working electrode surface. Among the carbon nanomaterials, the common and cost-effective carbon black has recently attracted the attention from the scientific community for its outstanding features as electrode nanomodifier for analyte detection. Herein, we report the structural and morphological characterisation of several types of carbon blacks, namely HP 160, HS20, MTN 990, N115, N220, N375, N660, PL6, Super P, and XE2B, by means of Raman spectroscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) analyses. Furthermore, the electrochemical characterisation of screen-printed electrodes modified with these carbon blacks was carried out by cyclic voltammetry and electrochemical impedance spectroscopy with ferro/ferricyanide as redox probe, highlighting the advantage to use carbon black as nanomodifier in respect to the bare electrode. Among several tested carbon black types, the lowest peak-to-peak separation and resistance to electron transfer values were achieved using screen-printed electrodes modified with CB N115, N375, HP 160 and PL6. The electrodes modified with these types of CB were successively tested in cyclic voltammetry towards epinephrine, benzoquinone, ascorbic acid, cysteine, catechol, and caffeic acid, observing a remarkable improvement of electrochemical performances in respect to the bare electrode, even when the amperometric mode was used. The results obtained demonstrated that several types of CB can remarkably improve the electrochemical performances of the sensors in terms of the decrease of applied potential or peak-to-peak separation, the improvement of the peak intensity, and the decrease of the resistance of the electron transfer due to several key features, including nanodimensions, the onionlike carbon structure, and the high number of defect sites.

“…The covalent functionalization of carbon-based materials primarily changes the hybridization of carbons in sp 2 to sp 3 . This functionalization does not only happen with mono-, di-, or triamine groups but also with various hetero-atoms including P, B, and O which can be incorporated onto the carbon network of graphene material (Lin et al 2018;Fei et al 2019). The inorganic complexes or nanocomposites have also been introduced on to the carbonbased graphene through covalent modification.…”

“…Metal‐free carbon‐based materials could possess the high activity towards CDRR by introducing heteroatoms to either being the active site or activating nearby carbon atoms as active sites . For example, pyridinic nitrogen has been widely proved to activate graphene, carbon nanotube, and nanodiamond . Boron, phosphorus, and fluorine activating strategies have also been proved successfully, with an example of fluorine dopant improving the j CO with 250,000 times enhancement over the commercial carbon material .…”

To realize renewable energy storage with a reduced carbon footprint for replacing fossil fuel and closing the unbalanced carbon cycle, electrochemical CO 2 splitting, commonly containing aqueous CO 2 reduction and water oxidation as core reactions, has received booming interest for its unique ability to produce chemicals and fuels from CO 2 powered by renewable electricity. In this Review, recent progress of electrochemical CO 2 splitting from a fundamental understanding to practical control of the main performance index, including production rate, product selectivity, and energetic efficiency, is discussed with the highlight of the methodologies used to increase CO 2 supply in water media and active site design. The roles of the main components in electrochemical CO 2 splitting devices, such as catalyst, electrode, electrolyzer, membrane, and electrolyte, are discussed. Finally, we also provide personal perspectives to highlight the opportunities to overcome low stability and limited selectivity for practical electrochemical CO 2 splitting.[a] Dr.

Catalysis by hybrid sp²/sp³nanodiamonds and their role in the design of advanced nanocarbon materials

Abstract: Hybrid sp2/sp3nanocarbons, in particular sp3-hybridized ultra-dispersed nanodiamonds and derivative materials, such as the sp3/sp2-hybridized bucky nanodiamonds and sp2-hybridized onion-like carbons, represent a rather interesting class of catalysts still under consideration.
