A hybrid structure, a graphitic nanostructures@porous carbon framework, is developed by utilizing the bimetallic zeolitic imidazolate framework-8 (ZIF-8) as a solid precursor, simultaneously templating porous carbon and growing graphitic nanocarbon in a simplified chemical vapor deposition (CVD) fashion. A ligand, 2-methylimidazolate (2MIM), in the ZIF-8 decomposes above 600 C to yield active c...

Catalytic substrate, which is devoid of expensive noble metals and enzymes for hydrogen peroxide (H₂O₂), reduction reactions can be obtained via nitrogen doping of graphite. Here, we report a facile fabrication method for obtaining such nitrogen doped graphitized carbon using polyacrylonitrile (PAN) mats and its use in H₂O₂ sensing. A high degree of graphitization was obtained with a mechanical...

To be able to successfully measure radiocarbon with accelerator mass spectrometry (AMS) in atmospheric aerosol samples, graphitization of small sample sizes (< 50 g carbon) must provide reproducible results. At Lund University, a graphitization line optimized for small samples has been constructed. Attention has been given to minimize the reduction reactor volume and each reactor is equipped w...

Most graphites used recently in industrial processes are synthetic. The issue is that non-renewable carbon precursors frequently the conventional graphitization process, which uses a lot of energy. purpose this research to synthesis graphite from mesocarp fiber waste derived palm oil. When carbonized, lignocellulosic biomass like oil typically produce ungraphitizable carbon. novelty investigati...

Invited for this issue's Front Cover is the group of Prof. Dr. Martin Winter from MEET Battery Research Center (University Münster, Germany). The cover picture shows two battery-shaped coffee cups filled with coffee. In addition, scientists (represented by gloved hands) have added both pure iron and an solution to cups. left cup highly energetic strikes sparks, indicating better electrochemical...

A series of non-precious metal electrocatalysts, namely pyrolyzed carbon-supported cobalt-polypyrrole, Co-PPy-TsOH/C, are synthesized with various cobalt precursors, including cobalt acetate, cobalt nitrate, cobalt oxalate, and cobalt chloride. The catalytic performance towards oxygen reduction reaction (ORR) is comparatively investigated with electrochemical techniques of cyclic voltammogram, ...

In this work, we systematically investigate the ‘catalytic’ graphitization of a biomass precursor (coffee ground) using 10–60 wt. % activator iron (III) chloride hexahydrate in temperature range 1000 °C – 2400 °C. Special focus is put on correlation synthesis conditions, e. g., heat treatment and mass fraction chloride, with electrochemical performance carbon||Li metal cells. The structural inv...
