Three-dimensional palm frondlike Co3O4@NiO/graphitic carbon composite for photocatalytic CO2 reduction

Lang He et al.

Summary: Three-dimensional palm frondlike S-scheme heterojunction based Co3O4@NiO/graphitic carbon composites were fabricated as photocatalysts for CO2 reduction reactions. The optimal Co@Ni/GC-700 catalyst exhibited excellent performance and stability with maximum yields of 9.79 µmol g-1h-1 for CH4 and 4.89 µmol g-1h-1 for CO under visible light irradiation. The superior photocatalytic CO2RR activity of the Co@Ni/GC catalysts can be attributed to the direct S-scheme heterojunction induced by the interfacial electric field (EF) and the improved CO2 adsorption capacity.

Yumei Ren et al.

Summary: This study develops an amorphous molybdenum oxide (a-MoO3_x) nanodots anchored on g-C3N4 as a highly active photocatalyst by integrating vacancy engineering and phase engineering. The Z-scheme a-MoO3_x/g-C3N4 heterostructure, with the high localized surface plasmon resonance (LSPR) effect and tunable electrical properties, exhibits broadband absorption and excited photo-generated electrons. The enhanced photocatalytic and photothermal performance is mainly attributed to the highly localized Anderson tail states of a-MoO3_x. Consequently, the a-MoO3_x/g-C3N4 heterostructure shows a photocurrent density of -36.5 mu A cm_2, which is about 2.7 and 4.1 times higher than that of pure g-C3N4 nanosheets (-13.5 mu A cm_2) and a-MoO3_x nanodots (-9 mu A cm_2), respectively.
