A two-dimensional/two-dimensional (2D/2D) TiO/ZnInS photocatalyst was reasonably proposed and constructed by a two-step oil bath-hydrothermal method. TiO nanosheets uniformly grown on the surface of ZnInS nanosheets and a synergetic effect between the TiO and ZnInS could highly contribute to improving the specific surface area and hydrophilicity of ZnInS as well as accelerating the separation and transfer of photon-generated e-h pairs, and thus enhancing the visible-light photocatalytic degradation and H evolution performance of ZnInS. Rhodamine B (RhB) and tetracycline (TC) were simultaneously selected as the target pollutants for degradation in the work.

The findings demonstrate that MoS HNS/ZnInS heterojunctions exhibited remarkably boosted photocatalytic properties and excellent reusability for both RhB degradation and H evolution without the use of Pt as a co-catalyst. Among the heterojunctions, the RhB degradation and H evolution efficiencies of the optimized MoS HNS/ZnInS-3 wt % composite were almost 5 and 34 times higher than those of ZnInS, respectively.

Herein, by simply calcining the mixture of ultrathin g-CN(CNN) and NaBH, heteroatom B and N defect were simultaneously introduced into g-CN. The obtained modified g-CN(BDCNN) was further coupled with 2D flower-like CdS nanosheet.

Through optimizing the proportion of ZnInS and CdS component, g-CN nanosheets coupled with ZnInS nanosheets and CdS nanoparticles (denoted as CdS/ZnInS/g-CN) exhibited obviously higher photocatalytic properties for RhB removal than the single-component and dual-component systems. Among the as-obtained ternary photocatalysts, it was found that the ternary CdS/ZnInS/g-CN-0.

In this study, CuS/g-CNheterojunction was formed byself-assembly via a simply hydrothermal method. A series of characterizations were applied to analyzing the morphology, structure, optical properties and photo-induced electron transfer of the samples.

The optimal SiC/C/g-CNcomposite shows an excellent visible-light photocatalytic activity for water splitting, with the highest hydrogen evolution amount being 200.2mol, which is four times higher than that of pure g-CNwhen triethanolamine and platinum (1.

The photocatalytic activity of SAPO-5/g-CN is evaluated by degrading RhB (30 mg/L) under visible light illumination (λ > 420 nm). The effects of SAPO-5 incorporation proportion and initial RhB concentration on the photocatalytic performance have been discussed in detail.
