Experimental and theoretical investigation on facet-dependent MoO2/BiOBr Z-scheme heterojunction photocatalytic nitrogen reduction: modulation of bulk charge separation efficiency by built-in electric field intensity

Based on facet engineering and Z-scheme heterojunctions, a series of MoO 2 /BiOBr Z-scheme heterojunctions with different facet ratios of (102)/(001) were prepared for photocatalytic nitrogen reduction.
