The influence of calcination temperature on iron oxide (α-Fe2O3) towards CO2 adsorption prepared by simple mixing method = Kesan suhu pengkalsinan ferum oksida (α-Fe2O3) disediakan melalui kaedah campuran ringkas terhadap penjerapan CO2

Synthesized iron oxide, α-Fe2O3 used for CO2 capturing was prepared by a simple mixing method and calcined at temperatures in a range of 350 – 850 °C. CO2 adsorption isotherms at 25 °C and 1 atm found that the sample namely s450 that calcined at 450 °C gave the highest CO2 adsorption activity with t...
