Preparation of CdS-g-C3N4/C composites via hollyhock stem biotemplate and its photocatalytic property

Biotemplated heterostructure materials: opportunities for the elaboration of new photocatalysts and selective-oxidation catalysts

“…Nanostructured heterojunction photocatalysts are considered very promising for various applications. [47][48][49][50][51][52] For instance, a nanocomposite consisting of anatase TiO 2 and wurtzite ZnO nanoparticles was successfully developed via a simple sol-gel and hydrolysis process using the biological template celery stalk. 48 A novel three-dimensional spherical LaFeO 3 /Bi 2 O 3 heterojunction was successfully constructed through a two-step synthesis including a biological template method and hydrothermal synthesis.…”

“…Hollyhock stem was used as a biological template to prepare a porous CdS–g-C 3 N 4 /C composite with n–n heterojunction. 49 Photoelectron–hole pairs are easily separated, which results in a longer life and a stronger activity in the photocatalytic reaction. The construction of heterojunction structure by a residual template method provides a new way for the preparation of cheap and stable photocatalysts.…”
