DESIGNING A HYBRID ADSORBENT/PHOTOCATALYST FOR CO2 CAPTURE AND PHOTOCATALYTIC CONVERSION

摘要

Great efforts have been made to reduce CO2 emissions through two primary routes: (1) CO2 capture and sequestration (CCS) and (2) CO2 conversion and utilization (CCU). However, in CCS besides the Crystal structure and morphology. All the MgAl/Tix samples maintained a high crystallinity of TiO2 and exhibited a cotton-like morphology, as evidenced by scanning electron microscopy (SEM). The high resolution transmission electron microcopy (HRTEM) image clearly shows well-faceted nanocrystals with an average size of 7 nm are well-dispersed on the surface of MgAl. The interplanar spacing around 0.34 nm matches the (101) plane of TiO2 anatase phase.
