CuCoO₂/CuO heterostructure: understanding the role of band alignment in selective catalysis for overall water splitting

Abstract

Employing a facile one-pot hydrothermal synthesis approach, in this work, we achieved the successful synthesis of a CuCoO2/CuO heterostructure, which was characterized by an atomic-scale intimately bonded interface.

“…The observed potentials in the individual components perfectly fit in the straddling type-1 band alignment, an arrangement well appreciated for photoemission and anticipated to have limited efficiency for photocatalysis. However, with the slight interfacial modifications targeted toward the mitigation of charge recombination, the type-I band alignment has been seen to deliver exceptional photocatalytic performance. − The interplay between interfacial electric fields and the conductivity of interfacial layers can significantly influence electron–hole dynamics, thereby impacting photocatalytic performance. , The observed band features of constituting ba-g-C 3 N 4 and MOF-derived Ni 2 P (which inevitably has a carbon layer, as evidenced by Figure S8) strictly justify their choice to be employed for the formation of composite photocatalysts for effecting the targeted organic transformations. With the present band setting, the composite photocatalyst well fits the bill for suitable aerobic oxidation reactions given the fact that the band potential of −0.38 eV vs NHE (CB of Ni 2 P) can easily generate O 2 –• radicals (redox potential of −0.33 eV vs NHE) that can initiate a good number of organic transformations .…”
