A Recent Review on Photocatalytic CO2 Reduction in Generating Sustainable Carbon-Based Fuels

One-step synthesized Nb2O5−y-decorated spinel-type (Ni,V,Mn)3O4−x nanoflowers for boosting electrocatalytic reduction of nitrogen into ammonia

“…78 The V O 2+ sites are electron deficient and can be filled by absorbing O 2− of OH − /H 2 O from the reaction environment to form (HO) O,ad. + , as shown in eqn (6). The weakly bonded (HO) O,ad.…”

“…+ can be replaced with a species under a stronger interaction, as indicated in eqn ( 6) and (7). During the progress of eqn (6) (10). Then, the formed H* is used to hydrogenate (N 2 ) O,ad.…”

“…3 Moreover, its substantial carbon footprint poses severe environmental challenges. [4][5][6] Therefore, in pursuit of environmentally sustainable NH 3 synthesis with zero carbon emissions, the electrochemical nitrogen reduction reaction (eNRR) has been developed.…”
