カーボン表面の組成・構造と酸素還元活性 https://www.jstage.jst.go.jp/article/tanso/2019/290/2019_029007/_article/-char/ja/ This article reviews the influence of heteroatom doping and the formation of warped graphitic layers on the catalytic activity of carbons for the oxygen reduction reaction (ORR). The development of a non-platinum cathode catalyst is key for the practical use of polymer electrolyte fuel cells (PEFCs), and carbon-based ORR catalysts are receiving special attention. First, we consider studies on the enhanced ORR activity of carbons caused by heteroatom doping. The type of dopant has been extende...続きを読む »

Influence of Low-temperature Oxidation on Structure of Coke Making Coal https://www.jstage.jst.go.jp/article/isijinternational/59/8/59_ISIJINT-2018-808/_article Self-exothermic reaction of coal is initiated by the reaction of coal in a pile with oxygen in the air to be oxidized. Then, the heat generated by the oxidation promotes further oxidation, resulting in ignition. In order to prevent this phenomenon, it is necessary to understand the initial stage of oxidation of coal in the condition of heat-accumulation. Conventionally, there are very few researches to understand the early stage of coa...続きを読む »
