Solid sorbents are considered to be promising materials for carbon dioxide capture. In recent years, many studies have focused on the use of solid waste as carbon dioxide sorbents. The use of waste resources as carbon dioxide sorbents not only leads to the development of relatively low‐cost materials, but also eliminates waste simultaneously. Different types of waste materials from biomass, industrial waste, household waste, and so forth were used as carbon dioxide sorbents with sufficient carbon dioxide capture capacities. Herein, progress on the development of carbon dioxide sorbents produced from waste materials is reviewed and covers key factors, such as the type of waste, preparation method, further modification method, carbon dioxide sorption performance, and kinetics studies. In addition, a new research direction for further study is proposed. It is hoped that this critical review will not merely sum up the major research directions in this field, but also provide significant suggestions for future work.

“…Some of the synthetic zeolites like 4A, 5A and 13X possess a number of properties that distinguish them from adsorbents of other types in decontaminating process. For instance, adsorption selectivity of polar molecules because of their highly localized polar charges on their surface that act as extremely effective adsorption sites for polar compounds (Mette, et al, 2014), high adsorption capacity at increased M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 2 temperatures (up to 100˚С) and low partial pressures of recovered component (Park, et al, 2012;Yu, et al, 2012) and uniform diameters of pore entrances they tend not to adsorb bigger molecules such as the heavy hydrocarbons (Dunne, et al, 1996;Harlick, et al, 2004). Therefore, in comparison to other adsorbents (silicagel, activated charcoal, magnesium silicate, etc.)…”

“…Fly ash has a high recycling rate and can be use in various parts of recycling systems while 79 % of bottom ash thrown and only 21 % was used in asphalt or in construction. Researchers had considerable interest in conversion of coal bottom ash and fly ash into zeolites or mesoporous silica materials as MCM-41, MCM-48 and SBA-15 [7]. Recently preparation of mesoporous materials from natural waste such as coal fly ash have been reported [8 -11].…”

Silica was extracted from power plant bottom ash by alkali fusion method and used to synthesize MCM-41 and SBA-15. As comparison, MCM-41 and SBA-15 were synthesized by using tetraethylorthosilicate (TEOS) as pure silica source. All synthesized MCM-41 and SBA-15 were characterized using X-ray Diffraction (XRD) and nitrogen adsorption to determine the formation of hexagonal pores, Field Emission Scanning Electron Micrograph (FESEM) was used to observe their morphology while Fourier Transform Infrared Spectroscopy (FTIR) was used to obtain the functional group and removal of surfactant after calcinations. XRD results confirmed bottom ash MCM-41 (BA MCM-41), pure SBA-15 (PSBA-15) and bottom ash SBA-15 (BA SBA-15) have well-ordered mesostructures. N 2 adsorption of pure MCM-41 (PMCM-41), PSBA-15 and BA SBA-15 indicated type IV isotherm while BA MCM-41 exhibit type III isotherm. According to FESEM analyses, the particle morphology of bottom ash mesoporous silica was different from those prepared using pure chemical. Morphology of PMCM-41 and PSBA-15 showed rod like particle while BA MCM-41 and BA SBA-15 exhibited agglomerated particle. PMCM-41, PSBA-15 and BA SBA-15 shows ordered hexagonal, high surface area and narrow pore distribution. Keywords: mesoporous silica, MCM-41, SBA-15Abstrak Silika telah diekstrak daripada abu bawah loji janakuasa melalui kaedah gabungan alkali dan digunakan untuk sintesis MCM-41 dan SBA-15. Sebagai perbandingan, MCM-41 dan SBA-15 telah disintesis dengan menggunakan tetraetilortosilika (TEOS) sebagai sumber silika tulen. Semua MCM-41 dan SBA-15 yang telah disintesis dicirikan menggunakan kaedah pembelauan Sinar X (XRD) dan penjerapan nitrogen untuk menentukan pembentukan liang heksagon, mikroskopi elektron pengimbasan pancaran medan (FESEM) digunakan untuk memerhati morfologi manakala Spektroskopi Inframerah Tranformasi Fourier (FTIR) digunakan untuk mengenalpasti kumpulan berfungsi dan penyingkiran surfaktan selepas pengkalsinan. Keputusan XRD membuktikan debu MCM-41 (BA MCM-41), SBA-15 tulen (PSBA-15) dan debu SBA-15 (BA SBA-15) mempunyai mesostruktur yang teratur. Penjerapan N 2 oleh MCM-41 (PMCM-41), PSBA-15 dan BA SBA-15 menunjukkan isoterma jenis IV manakala isoterma jenis III bagi BA MCM-41. Berdasarkan analisis FESEM, morfologi zarah silika mesoporos daripada debu bawah loji janakuasa adalah berlainan berbanding yang disediakan menggunakan bahan kimia tulen. Morfologi PMCM-41 dan PSBA-15 menunjukkan zarah jenis rod manakala BA MCM-41 dan BA SBA-15 wujud sebagai zarah bercampur. PMCM-41, PSBA-15 dan BA SBA-15 mempunyai struktur heksagon yang seragam, luas permukaan yang tinggi dan taburan liang yang kecil.
