Summary: The interaction of single Fe, Co, Ni, and Cu atoms with polar terminations of orthorhombic Mo2C(0 0 1) surface has been studied using density functional theory. The results show high stability of all adsorbates regardless of the surface termination. The presence of a single foreign atom affects the properties of the surface, causing charge redistribution and lowering of the work function. The adsorption energy weakening of atomic hydrogen caused by the foreign adatom suggests an enhancement in the catalytic activity of Mo2C towards hydrogen evolution reaction.

Summary: Coupling graphene-based materials with SiC nanostructures is an effective strategy for improving photocatalytic CO2 reduction performance. In this study, vertical graphene (VG) sheets were synthesized on SiC nanowires derived from rice husks to form the VG@SiC/C composite. The resulting composite exhibited enhanced photocatalytic CO2 reduction, yielding CO and CH4 with yields of 25.5 and 2.3 μmol g-1 h-1, respectively, which is the highest CO yield among SiC-based photocatalysts. Defective VG sheets promoted sunlight absorption, CO2 adsorption and activation, electron-hole pair separation, and overall photocatalyst activity, leading to high CO2 reduction yield and selectivity.

Summary: Photocatalysis has the potential to reduce CO2 greenhouse gases. Layered double hydroxides (LDHs) are promising photocatalysts with good catalytic activity, low synthesis cost, and large-scale preparation. This study focused on the effects of different divalent metal species on CO selectivity in aluminum-based LDHs and found that ZnAl-LDH exhibited better CO selectivity and CO yield compared to MgAl-LDH and NiAl-LDH. These findings provide a feasible strategy to improve the selectivity of CO photocatalytic reduction of CO2 by regulating divalent metal species in aluminum-based LDHs.
