Self-assembly of a heterogeneous microreactor with carbon dots embedded in Ti-MOF derived ZnIn2S4/TiO2 microcapsules for efficient CO2 photoreduction
The assembly of the heterogeneous microreactor is a promising approach for CO2 photoreduction attributed to its abundant microchannel, intimate contact, high exposed surface area, and favorable heat-mass transfer.

N-rich porous carbons with tunable affinity for CO2 adsorption achieve size-sieving CO2/N2 selectivity in turbostratic interlayers
Carbons with varying porosity and N-content exhibit tunable thermodynamics of CO2 adsorption, stemming from synergy between confinement and surface chemistry. Further, size-sieving CO2/N2 adsorption selectivity occurs in sub-nanoscale interlayers.
