Plasma science has attracted the interest of researchers in various disciplines since the 1990s. This continuously evolving field has spawned investigations into several applications, including industrial sterilization, pollution control, polymer science, food safety and biomedicine. nonthermal plasma (NTP) can promote the occurrence of chemical reactions in a lower operating temperature range, condition in which, in a conventional process, a catalyst is generally not active. The aim, when using NTP, is to selectively transfer electrical energy to the electrons, generating free radicals through collisions and promoting the desired chemical changes without spending energy in heating the system. Therefore, NTP can be used in various fields, such as NO removal from exhaust gases, soot removal from diesel engine exhaust, volatile organic compound (VOC) decomposition, industrial applications, such as ammonia production or methanation reaction (Sabatier reaction). The combination of NTP technology with catalysts is a promising option to improve selectivity and efficiency in some chemical processes. In this review, recent advances in selected nonthermal plasma assisted solid-gas processes are introduced, and the attention was mainly focused on the use of the dielectric barrier discharge (DBD) reactors.
自20世纪90年代以来，等离子体科学吸引了各个学科研究人员的关注。这个不断发展的领域催生了对多种应用的研究，包括工业灭菌、污染控制、聚合物科学、食品安全和生物医学。非热等离子体（NTP）可以在较低的操作温度范围内促进化学反应的发生，而在传统工艺中，在这种条件下催化剂通常没有活性。使用NTP的目的是将电能选择性地转移到电子上，通过碰撞产生自由基，并促进所需的化学变化，而无需在加热系统上消耗能量。因此，NTP可用于各个领域，如从废气中去除NO、从柴油机尾气中去除烟灰、挥发性有机化合物（VOC）分解、工业应用，如氨生产或甲烷化反应（萨巴蒂尔反应）。NTP技术与催化剂的结合是提高某些化学过程选择性和效率的一个有前景的选择。在这篇综述中，介绍了选定的非热等离子体辅助固气过程的最新进展，并且主要关注了介质阻挡放电（DBD）反应器的使用。
