Abstract

The photoelectrochemical application of carbon nitride is extremely exciting because of the meta-free components, low cost, nontoxicity, and appropriate band positions. To construct carbon nitride-based heterostructures, a conventional ultrasonic exfoliation method is usually used to fabricate dispersion of ultrathin nanosheets. However, the outstretched structure and the poor dispersity inevitably result in the poor interfacial contact between different materials. To solve this problem, hydrolyzed carbon nitride suspension was used as a homogeneous precursor for the fabrication of composite photoanodes. The in situ reassembly of one-dimensional nanofibers resulted in the formation of uniform and ultrathin carbon nitride nanoarchitectures on the surface of Fe2O3 nanorod arrays. Because of the strongly coupled interfaces and the deposition of Co
