Pyrolysis behaviors of coal-related model compounds catalyzed by pyrite
Pyrite Catalytic pyrolysis Coal-related model compounds Tetrahydronaphthalene
2023/6/19
The pyrolysis behaviors of coal-related model compounds (bibenzyl and benzyloxybenzene) were investigated on a fixed-bed reactor catalyzed by pyrite (main component is FeS2). The pyrolysis products we...
近日，中国科学院合肥物质科学研究院固体物理研究所研究员张永胜课题组在三种Pyrite型IIB-VIA2（ZnS2、CdS2和CdSe2）过渡金属二硫化物的热电性能研究方面取得新进展。该研究计算分析了三种不同Pyrite型二元硫化物的热学和电学输运性质，发现它们均具有良好的热电性能；分析了与原子成键、晶格振动和电子结构分布间的热电趋势。相关研究成果发表在Physical Review B上。
