Abstract

Porous carbon is a promising research subject for CO2 capture from post combustion process, direct air capture and recently for hydrogen fuel purification application. Apart from having unique surface area and pore morphology, they can be also be prepared from low cost materials through easy synthesis route. The tuning of their pore size and N heteroatom have also proven to robust its performance in previous studies. Therefore a highly porous N-doped carbon nanoflakes from starch was prepared and its performance in CO2 capture was studied. Among the samples, starch hybrid (SH800) exhibit good CO2 capture capacity of 29.8 wt.% for biohydrogen gas adsorption at mild temperature and pressure. The sample also displayed distinct morphology of nanoflakes and carbon lattice in FESEM and XRD analysis. In summary, the sorbent is a potential material for biohydrogen CO2 capture studies.
