Special Issue Information

Dear Colleagues,

Building upon the success of the first edition, we now continue onto the second edition. We are pleased to invite you to contribute to this Special Issue of Inorganics, entitled Carbon Nanomaterials for Advanced Technology, 2nd Edition. Carbon nanomaterials have emerged, over the past few decades, as prime candidates for novel and next-generation applications in the technological materials space. Examples include graphene and carbon nanotubes for nanoelectronics, carbon nanoparticles for drug delivery systems and nanodiamonds in bioimaging. Their remarkable mechanical, thermal and electronic properties have attracted broad scientific attention and can be tailored for functional applications across all dimensions.

Significant steps in the synthesis of carbon nanomaterials have been realized in recent years; these range from rapid processes aimed at scaling up production to highly controlled conditions aimed at achieving selective growth. With the aim of unlocking the full potential of carbon nanomaterials, both experimental and theoretical techniques have been utilized. This has and will lead to the incorporation of carbon nanomaterials in advanced technologies.

This Special Issue aims to include a collection of original research articles and reviews that reflect recent progress into understanding, synthesizing, and applying carbon nanomaterials. Contributions concerning all kinds of carbon nanomaterials are welcome, with a focus on employed experimental and/or theoretical techniques involving the implementation of carbon nanomaterials in emerging and advanced technology. These technologies could involve (but are not limited to) nanoelectronics, sensing, bioimaging, biomedicine, catalysis, mechanical reinforcement and photocatalysis.

We are looking forward to receiving your contributions.

Realistic applications of zinc–air batteries are hindered by the high cost of Pt/C cathode catalysts, necessitating the search for alternative, sustainable electrocatalysts. In this work, we developed a sustainable Fe3C/Fe-Nx-C cathode catalyst from waste coffee biomass for an oxygen reduction reaction (ORR) in alkaline electrolytes and zinc–air battery applications. The Fe3C/Fe-Nx-C cathode catalyst was synthesized via a mechanochemical synthesis strategy by using melamine and an EDTA–Fe chelate complex, followed by pyrolysis at 900 °C. The obtained Fe3C/Fe-Nx-C catalyst was evaluated for detailed ORR activity and stability. The ORR results show that Fe3C/Fe-Nx-C displayed excellent ORR activity with an E1/2 of 0.93 V vs. RHE, a Tafel slope of 68 mV dec−1, 3.95 e transfer for the O2 molecule, and high ECSA values. In addition, the Fe3C/Fe-Nx-C catalyst exhibited excellent stability with a loss of 75 mV for 10,000 potential cycles, and a loss of ~14% of relative currents in the chronoamperometric test. When applied as a cathode catalyst in zinc–air battery, the Fe3C/Fe-Nx-C catalyst delivered a power density of 81 mW cm−2 and admirable electrochemical stability under galvanostatic discharge conditions. Furthermore, the practical application of the Fe3C/Fe-Nx-C catalyst was demonstrated by a panel of LEDs illuminated with a dual-cell zinc–air battery connected in a series, clearly validating the practically developed catalysts for use in various energy storage and electronic devices.
