Addressing the challenge of increasing the rate of CO₂ capture by accelerating the hydration process, we proposed the use of a new class of heterogeneous inorganic catalysts for this purpose. The presented research focused on Co₃O₄-based nanocatalysts produced by low-pressure plasma deposition (PECVD) in the form of thin films that can be deposited on any structured packing. The kinetic studies of this process were performed by bubbling CO₂ through pure water with catalytic or inert packing, measuring changes in pH value over time. The developed kinetic model described the experimental data very well and showed that the reaction at the interface between the CO₂ bubble and the catalyst surface is responsible for the catalytic effect. Studies of the molecular structure of the catalyst surface, carried out by the XPS technique, showed that the chemisorbed H₂O clusters on this surface are the active centers for the interaction with gaseous CO₂.

为了解决通过加速水合过程来提高 CO ₂捕获率的挑战，我们建议为此使用一类新型的非均相无机催化剂。所提出的研究重点是通过低压等离子体沉积 (PECVD) 以薄膜形式生产的基于Co ₃ O ₄的纳米催化剂，该薄膜可以沉积在任何结构化填料上。该过程的动力学研究是通过将 CO ₂鼓泡在带有催化或惰性填料的纯水中，测量 pH 值随时间的变化来进行的。开发的动力学模型很好地描述了实验数据，并表明 CO ₂气泡和催化剂表面负责催化作用。通过 XPS 技术对催化剂表面的分子结构进行的研究表明，该表面上化学吸附的 H ₂ O 团簇是与气态 CO ₂相互作用的活性中心。
