Study of amino-modified resorcinol-formaldehyde aerogels for odorous gas removal
When it comes to owning pets, pet odor is a major concern for many individuals. Ammonia (NH3) and hydrogen sulfide (H2S) are the primary odor components that have negative effects on human life. Therefore, there is an urgent need to develop a deodorizing material with high NH3 and H2S adsorption capacity. In this study, Resorcinol-formaldehyde (RF) aerogels containing amine groups (RF-Mx) were prepared using the sol-gel method and atmospheric pressure drying technique. Melamine was used as a modifier. The specific surface area of the modified aerogel was 119 m2/g with an average pore size of 12 nm when the melamine addition was 20%. The adsorption capacity of RF-M20 for odor was the highest (NH3: 593.8 mg/g, H2S: 640 mg/g), which was significantly superior to the unmodified sample. In addition, the adsorption capacity of RF-M20 for H2S exceeded that of commercial activated carbon. The results concluded that the introduction of amine groups and the higher microporous specific surface area benefited the chemical and physical adsorption of gases, effectively improving the adsorbent’s capacity to capture NH3 and H2S. The preparation method is not only efficient in enhancing the odor adsorption capacity but also simple and cost-effective to operate, showing promising potential for industrial applications.
期刊介绍:
The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication
of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to
establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials.
Porous materials include microporous materials with 50 nm pores.
Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti
phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass
ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials
can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall
objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
