Preparation and characterization of carbon molecular sieves from chestnut shell by chemical vapor deposition

A Review on Sustainable Manufacturing of Ceramic-Based Thin Films by Chemical Vapor Deposition (CVD): Reactions Kinetics and the Deposition Mechanisms

“…Chlorides, fluorides, and bromides are present in CVD technology, where they contain various metals in the liquid or gas state. These materials are volatile, and they are suitable alternatives for the deposition of different materials on various substrates [112][113][114][115][116][117][118].…”

A review of CO2adsorbents performance for different carbon capture technology processes conditions

“…Carbon molecular sieve (CMS) belongs to a special group of activated carbon. 220 Similar to the activated carbon, the CMS has an amorphous microporous structure with a pore size similar to that of the critical adsorbate sizes (i.e., 0.330 nm for CO 2 , 0.380 nm for CH 4 , 0.364 nm for N 2 , and 0.346 nm for O 2 ) 221 and smaller pore surface area. 222,223 It can be prepared from any inexpensive carbonaceous material with low inorganic compounds such as lignocellulosic materials, biomass and coal by pyrolyzation, covering, and carbon deposition methods.…”

“…[222][223][224][225][226][227][228][229][230][231][232] The chemical vapor deposition (CVD) method utilizes carbon deposition agents such as acetylene, 233 benzene, 221,229,234 methylpentane, 227 cyclohexane, 229 and methane 235,236 either in liquid or vapor form for pyrolytic carbon deposition at pore mouth to match the pore entrance with the adsorbate size. 220 The advantage of using CMS-based CO 2 adsorbent is its versatile selectivity for gas molecule separation with different molecular sizes. 237 Different molecules based on the molecular size, shape, diffusion rate, or adsorption equilibrium can be separated due to their microporous structure and micropore size distribution.…”

“…In addition to its low CO 2 adsorption capacity, the CMS is not favored as a CO 2 adsorbent due to its high toxicity and high cost of depositing agents. 236,241 It can also generate intermediates during the deposition process 220,233,236 and the CO 2 adsorption performance is dependent on the pyrolytic reaction or carbon deposition conditions. 221,242 Layered anionic clays Layered double hydroxides (LDHs) are classified as synthetic anionic clays.…”

Integrated High Water Affinity and Size Exclusion Effect on Robust Cu-Based Metal–Organic Framework for Efficient Ethanol–Water Separation

“…By virtue of the advantages of easy operation conditions and energy-savings, adsorption separation is regarded as a relatively green and sustainable separation technology, in which the ideal adsorbent is the key factor to achieve efficient separation targets . Compared with traditional solid porous adsorbents such as silicates, zeolites, and carbon molecular sieves, burgeoning metal–organic framework (MOF) materials featuring high specific surface areas and high crystalline content can be rationally designed with anticipative structures and pores. − Thus, they are recognized to be promising candidates for efficient adsorbent materials. , As a result, they have been widely applied to various adsorption separation applications, including CO 2 capture, , hydrocarbons separation, , and so on. − The potential application of MOFs in water–ethanol separations also have been investigated in recent years. , Among them, the major strategies for water–ethanol separation with well-designed MOFs rely on the differences in interaction forces between MOFs and water or ethanol, the pressure-dependent gate-opening effect of MOFs, and the space constraint effect derived from molecular size and fixed channel structure; all of these are summarized in Figure a–c. The separation types based on interaction force differences (Figure a) and flexible organic linkers (Figure b) reflect the coadsorption process, which both will cause the elimination of the target extract.…”
