Abstract
Preparation and properties of porous carbon material containing magnesium oxide Porous carbons loaded with magnesium oxide were prepared through one-step process. Poly(ethylene terephthalate) and natural magnesite were used as carbon source and MgO precursor, respectively. An impact of a temperature and relative amounts of raw components used for preparations on the textural parameters of resulting hybrid materials is presented and discussed. As found, pore structure parameters tend to decrease along with MgO loading and temperature used during preparation process. Micropore area is the parameter being reduced primarily.
Highlights
In recent years there has been a rapid progress in many industries, in the manufacture of advanced devices based on semiconductors, pharmaceuticals, or in biotechnology
Highly efficient removal of acid gases such as SO2 and CO2 exhibit porous carbons loaded with bases like NaOH, KOH, or K2CO310
The aim of this study was to develop a simple method for obtaining new carbon sorbent containing magnesium oxide (MgO), from readily available and economically attractive raw materials
Summary
In recent years there has been a rapid progress in many industries, in the manufacture of advanced devices based on semiconductors, pharmaceuticals, or in biotechnology. One of the key factors regularly required to carry out production processes with the advanced processes is a purity of the technological media, including air This requires utilization of effective filtering devices capable to remove from large volumes of the air impurities to achieve desired levels. Both efficiency and selectivity of these adsorbents can be modified by a proper chemical treatment or by loading suitable chemicals intentionally chosen to remove specific gases from the air[2,3,4,5]. In this way so called chemical filters are manufactured. Carbon adsorbents loaded with additives can be prepared by so called blending method, consisting in thermal treatment of carbon precursor with a precursor of an additive[11]
