Abstract: Hydrogen is crucial in the global shift towards clean energy and is gaining significance in the energy industry, while its high flammability and explosive hazard make its safety a research hotspot. It is crucial to thoroughly investigate and assess the safety of hydrogen as it progresses toward commercialization in the energy sector. This article reviews the latest advancements in hydrogen explosion suppression conducted by researchers around the world, aiming at offering a scientific foundation and technical approach to efficiently manage and reduce the damaging impacts of hydrogen explosion incidents. The article focuses on the study of hydrogen explosion suppression materials and their suppression mechanisms, so as to provide scientific understanding and technical support for the safe application of hydrogen. Firstly, it systematically introduces the research progress in hydrogen explosion suppression by discussing four significant categories, i.e., gas, liquid, solid, and multiphase composite explosion suppression materials. By comparing and analyzing the effects, key performance parameters, and the variation rules of these materials, the current research status and effectiveness of various explosion suppression materials are sorted out, helping to deepen the understanding of the explosion suppression effects of these materials. Secondly, focusing on the suppression mechanism, the research delves into the vital role of explosion suppression materials in suppressing hydrogen explosions. Starting from three dimensions, i.e., physical suppression, chemical suppression, and physicochemical comprehensive suppression, it elucidates the mechanisms of action of explosion suppression materials in the suppression process, contributing to a deeper understanding of the role of explosion suppression materials in suppressing or mitigating hydrogen explosions. Finally, the article looks forward to the future development directions of hydrogen explosion suppression materials, especially emphasizing the importance of further studies on the high-efficiency explosion suppression materials and the challenges faced in practical applications. This review is aimed to provide scientific reference and inspiration for the research, development, and application of new hydrogen explosion suppression materials.

表 2 CO₂等不活泼气体抑制氢气的实验研究^[21-30]

Table 2. Experimental studies on the inhibition of hydrogen by inert gases, including CO₂^[21-30]

研究人员	研究对象	实验装置	抑爆剂	结论
刘原一等^[21]	H₂/CO	2 m长不锈钢管道	N₂、CO₂	CO₂对混合气爆燃特性的影响强于N₂，主要表现在燃爆下限和压力波传播上
Yan等^[22]	H₂/CO	球形爆炸室	N₂、CO₂	随着CO₂和N₂含量的增加，绝热火焰温度、热扩散系数和活性自由基摩尔分数不断降低，使层流燃烧速度降低。其次，CO₂抑制氢气爆炸压力比N₂更有效
Li等^[23]	H₂	肥皂泡装置	He、Ar、 N₂、CO₂	影响热扩散系数、绝热火焰温度、层流燃烧速度和热膨胀率的降低排序：He>Ar>N₂>CO₂，且N₂不存在第三体效应，第三体效应:CO₂>Ar>He，因此，CO₂是缓解氢气爆炸较为有效的添加物
Wei等^[24]	H₂	定容燃烧弹	Ar、N₂、CO₂	不活泼气体的稀释减缓了火焰在燃烧室中的传播。抑制作用由小到大依次是Ar、N₂、CO₂
Wang等^[25]	H₂	7.3 L圆筒封闭容器	Ar、N₂、CO₂	CO₂比热高于N₂和Ar，且CO₂对能量损失的增加最显著，N₂和Ar次之，故CO₂的抑制效果优于Ar和N₂
邹颖等^[26]	H₂	20L爆炸球	N₂、CO₂	CO₂在爆炸压力及压力增长率方面的抑制效果优于N₂
Wang等^[27]	H₂/LPG	20L爆炸球	N₂、CO₂	比较了爆炸压力、自由基的摩尔分数和产生速率，得出CO₂抑制作用优于N₂。其中N₂主要起到了物理抑制作用，而CO₂还发挥了化学抑制作用
Chang等^[28]	H₂	20 L标准球形爆炸容器中	N₂、CO₂	N₂、CO₂气体稀释的抑制作用可以平衡湍流的促进作用。在某些情况下，由于CO₂的分子量较大，其对爆炸行为的增强作用比N₂射流更明显
Wu等^[29]	H₂	圆柱形停滞室	N₂、CO₂	从火焰长度减速比的比较可知，CO₂与N₂的减缓效果非常接近
Zhang等^[30]	H₂	爆炸管道	N₂、CO₂	比较了爆炸压力、燃烧持续时间和火焰传播等爆炸参数，验证了CO₂比N₂抑制效果强。此外，多层爆炸抑制对不同侧缓蚀剂的抑制效果最好
