Efficiency of Aluminium-Based Nanoadsorbents for Carbon Monoxide Adsorption: Mini-Review
Background: Today, scientists are exploring the best technology to improve air quality for human health, which is especially important in conditions of actively developing technogenic activity and after emergencies. One of the pollutant gas that threats human health and the environment is carbon monoxide (CO). When planning and development of cities and regions, it is vitally important to organize proper gas cleaning to reduce CO in the environment, since this gas contributes to the destruction of the ozone layer and other negative effects in the atmosphere. Objectives: The current study aims to explore some of the features and the characteristics of such nanoadsorbents for the for CO adsorption from atmospheric air, with an emphasis on their potential prospects. Methods: A review of studies based on publications in peer-reviewed scientific journals was conducted. No restrictions were applied based on the language of publication, geographic location of authors or scientific journal, or time interval. Mostly the most recent publications and the most cited ones were taken into account. Results: It has been established that Among several phases (δ-, η-, θ-, and γ-) of alumina, γ-alumina that is recognized as transition alumina is the top choice for capturing CO gas because it has a large surface area, an excellent catalytic activity, pore-volume. The roll-coating method leads composite films to have special properties, such as a high mechanical property and surface area, simplicity to produce, and needless to pre-treated before use. It was found that the maximum adsorption efficiency for different alumina-doped adsorbents is about 94–98%. Conclusions: The roller coating method for the production of composite films has proven to be a simple, cheap and reliable method for producing an effective nanoadsorbent. Alumina-doped adsorbents deserve serious attention for further development, since they are quite capable of competing in efficiency, ease of manufacture and cost with commercial adsorbents available on the market.
