Preparation of nanoporous activated carbon and its application as nano adsorbent for CO2 storage

Preparation and evaluation of activated carbon from low-rank coal via alkali activation and its fundamental CO2 adsorption capacity at ambient temperature under pure pressurized CO2

“…According to previous reports, a KOH/C mixing ratio >2.0 was required to prepare activated carbon with a surface area of 2000 m 2 g −1 or more using KOH. 41,54,55 The volume of the mesopores tended to increase with an increase in the KOH content; 36,54,55 the volume of 0.3–0.4 nm pores decreased, while that of the 0.4–0.7 nm pores increased in the range of 500–800 °C. However, the latter decreased at 900 °C.…”

A one-step self-sustained low temperature carbonization of coconut shell biomass produced a high specific surface area biochar-derived nano-adsorbent

“…Therefore the biochar-derived adsorbent has the potential to be used as a nano-adsorbent. In a study by Rashidi et al (2016), the development of nano-porous activated carbon using walnut shells via chemical processes at high temperature resulted in 2.1 nm pore diameter and 0.46–0.93 cm 3 /g of total pore volume which was applied as a nano-adsorbent for CO 2 storage. Therefore, a wide distribution of pores on the biochar surface observed via SEM indicated that successful carbonization was achieved between 300 and 500 °C using the self-sustained pilot scale brick reactor.…”

Diamond-Like Carbon Nanofoam from Low-Temperature Hydrothermal Carbonization of a Sucrose/Naphthalene Precursor Solution

“…This can lead to a large variety of graphite-like morphologies with many possible applications. For example, it is responsible for the uptake of molecules such as methane [75], CO 2 [76], proteins [77], or heavy metals [78]. Also, catalytic properties of the foam [79], as well as gas- [80] and glucose-sensing properties [81] or photoluminescence [82] are related to a graphitic or graphene-like interior of the foams.…”
