The role of surface functionality of sustainable mesoporous materials Starbon® on the adsorption of toxic ammonia and sulphur gasses

Synthesis, characterisation and carbon dioxide capture capacities of hierarchically porous Starbons®

“…A800 (entries 37-41) and P800 (entries 42 and 43) were activated with carbon dioxide at lower temperatures (700-900 °C) than S800, but gave activated materials with much lower BET surface areas (up to 946 m 2 g −1 ). These materials also had lower micropore volumes (0.31-0.40 cm 3 g −1 ) than the S800 activated samples (entries [24][25][26][27][28][29][30][31][32][33][34][35][36], though this still represents a 2.4-3.6 fold increase on the micropore volumes of the A800 and P800 precursors (entries 5 and 6). The mesopore volumes also show a small increase compared to the unactivated precursors so that for A800 derived, carbon dioxide activated materials, the micropore volume is 29-31% of the total pore volume and for P800 derived materials it is 40-43% of the total pore volume.…”

“…28 They were subsequently shown to also adsorb ammonia, hydrogen sulphide and sulphur dioxide more effectively than microporous carbon. 29 The above applications all benefit from the favourable mass-transfer rates associated with highly mesoporous structures. However, for some of these applications, the higher surface area associated with a more microporous structure could be beneficial.…”

Highly Efficient Mesoporous Carbonaceous CeO2 Catalyst for Dephosphorylation

“…The FTIR analysis ( Figure 1 ) of the synthesized systems shows a weak, broad absorbance band centered at around 3300 cm –1 indicative of the O–H stretching frequency and a strong absorbance band at 1009 cm –1 due to the C–O stretching vibration, which decreases on pyrolysis. 19 In the case of CeO 2 -S400, the absorbance band at around 1014 cm –1 may be due to the CO 3 2– bending vibration and C–O stretching vibration, which may get trapped during the synthesis procedure. The absorbance band at 1655 cm –1 is synonymous with C=C stretching vibrations, 20 which indicates the existence of aromatic nature in the synthesized systems.…”

Simple, quick and green isolation of cannabinoids from complex natural product extracts using sustainable mesoporous materials (Starbon®)

“…The potential to vary the polysaccharide used and the pyrolysis temperature, has allowed for the materials’ properties to be highly tunable to the required application. To date, there have been over 50 Starbon related publications since their discovery, in a variety of fields including catalysis, 21 gas capture, 22 batteries, 23 metal recovery, 24 and water treatment. 25 Additionally there are two live patents relating to Starbons 26,27 with an associated start-up company.…”
