摘要
随着全球能源需求的增长和环境问题的加剧,开发新型高性能气体传感器变得尤为迫切。生物质炭材料是由生物质原料经过预碳化和活化处理获得,具有独特的孔隙结构、大的比表面积、丰富的表面活性官能团和活性位点,在气体传感检测领域具有巨大的应用潜力。本文按照生物质炭的主要来源对生物质进行了分类(植物基、动物基和微生物基)以及4种生物质炭材料的常见制备方法(水热炭化法、活化法、模板法和微波热解法)。本文重点讨论了生物质炭材料在半导体型气体传感器和非金属氧化物主导型气体传感器的最新研究进展,包括作为气敏材料在检测各类气体方面的应用。最后,分析了生物质炭基气体传感器目前需要解决的问题,为拓宽该类传感器的实际应用提出了研发的思路。
The development of new high-performance gas sensors has become particularly urgent with the growth of global energy demand and the aggravation of environmental problems.Biomass char materials are obtained from biomass raw materials through pre-carbonization and activation treatment,which have unique pore structure,large specific surface area,abundant surface active functional groups and active sites,and have great potential for application in the field of gas sensing and detection.In this paper,biomass is classified according to the main sources of biomass char(plant-based,animal-based,and microbial-based)as well as four common preparation methods of biomass char materials(hydrothermal carbonization,activation,templating,and microwave pyrolysis).The paper focuses on the recent research progress of biomass char materials in semiconductor-based gas sensors and non-metallic oxide dominated gas sensors,including their applications as gas-sensitive materials for the detection of various types of gases.Finally,the current problems that need to be solved for biochar-based gas sensors are analyzed,and ideas for research and development are proposed to broaden the practical applications of such sensors.
