1 Οκτ 2021 · Based on our results of CO 2 adsorption on MgO and Mg(OH) 2 surfaces, we identified three CO 2 polarization mechanisms, i.e. charge transfer to CO 2, electron localization within CO 2, and uneven electron distribution in two O atoms of CO 2, which are illustrated via variation of CO 2 electron localization function (ELF) after adsorption at ELF ...

30 Αυγ 2013 · By raising the pH without introducing CO 2 and producing Mg(OH) 2 instead of MgCO 3, a solid Mg(OH) 2 sorbent can be formed to capture CO 2 via high temperature gas–solid reactions: (5) Mg(OH) 2 (s)=MgO(s)+H 2 O(g) (6) MgO(s)+CO 2 (g)=MgCO 3 (s)
1 Φεβ 2024 · Abstract. Constructing photocatalysts with dual-function active sites can coordinate the photogenerated electrons transfer and the adsorption energy of key intermediates, thereby converting CO 2 into valuable methane with high efficiency.
