Twinned Growth of Metal‐Free, Triazine‐Based Photocatalyst Films as Mixed‐Dimensional (2D/3D) van der Waals Heterostructures( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: Design and synthesis of ordered, metal‐free layered materials is intrinsically difficult due to the limitations of vapor deposition processes that are used in their making. Mixed‐dimensional (2D/3D) metal‐free van der Waals (vdW) heterostructures based on triazine (C3 N3 ) linkers grow as large area, transparent yellow‐orange membranes on copper surfaces from solution. The membranes have an indirect band gap ( E g, opt = 1.91 eV, E g, elec = 1.84 eV) and are moderately porous (124 m 2 g −1 ). The material consists of a crystalline 2D phase that is fully sp 2 hybridized and provides structural stability, and an amorphous, porous phase with mixed sp 2 –sp hybridization. Interestingly, this 2D/3D vdW heterostructure grows in a twinned mechanism from a one‐pot reaction mixture: unprecedented for metal‐free frameworks and a direct consequence of on‐catalyst synthesis. Thanks to the efficient type I heterojunction, electron transfer processes are fundamentally improved and hence, the material is capable of metal‐free, light‐induced hydrogen evolution from water without the need for a noble metal cocatalyst (34 µmol h −1 g −1 without Pt). The results highlight that twinned growth mechanisms are observed in the realm of "wet" chemistry, and that they can be used to fabricate otherwise challenging 2D/3D vdW heterostructures with composite properties. Abstract : Mixed‐dimensional (2D/3D) layered, van der Waals heterostructures based on triazine linkers are produced in a facile, one‐pot, "wet" chemistry process. Macroscopic films of the material grow via a twinned mechanism—first, the 2D crystalline phase, then the 3D polymer—on a copper support that acts both as a catalyst and template, and form an efficient type I heterojunction
