Among all N-doped biochars, "the #biochar prepared with corncob🌽 powder, K2CO3 & urea at 800°C showed highest #adsorption ability (5.69 mmol/g at 0°C & 1 bar) & selectivity (38.24 at CO2/N2 = 10/90). The biochar also showed excellent thermal stability & cycle performance."

"Notable, correlation analysis showed that ultra-micropores were the decisive factor for #CO2 #adsorption at low temperatures; nevertheless, the effect of N-doping would gradually appear with the increase of adsorption temperature."
