Comprehensive Review on g-CN-Based Photocatalysts for the Photocatalytic Hydrogen Production under Visible Light.

Currently, the synthesis of active photocatalysts for the evolution of hydrogen, including photocatalysts based on graphite-like carbon nitride, is an acute issue. In this review, a comprehensive analysis of the state-of-the-art studies of graphic carbon nitride as a photocatalyst for hydrogen production under visible light is presented. In this review, various approaches to the synthesis of photocatalysts based on g-CN reported in the literature were considered, including various methods for modifying and improving the structural and photocatalytic properties of this material.

Composite photocatalysts based on Cd Zn S and TiO for hydrogen production under visible light: effect of platinum co-catalyst location.

Ternary composite photocatalysts based on titania and solid solutions of CdS and ZnS were prepared and studied by a set of physicochemical methods including XRD, XPS, HRTEM, UV-vis spectroscopy, and electrochemical tests. Two synthetic techniques of platinization of Cd Zn S/TiO were compared. In the first case, platinum was deposited on the surface of synthesized Cd Zn S ( = 0.

New titania-based photocatalysts for hydrogen production from aqueous-alcoholic solutions of methylene blue.

A series of CuO -TiO photocatalysts were prepared using fresh and thermally activated Evonik Aeroxide P25 titanium dioxide. The photocatalysts were characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, XANES, diffuse reflectance spectroscopy, and N adsorption technique. Photocatalytic activity of the samples was tested in hydrogen production from aqueous-alcoholic solutions of methylene blue under UV radiation ( = 386 nm).

The influence of the sacrificial agent nature on transformations of the Zn(OH)/CdZnS photocatalyst during hydrogen production under visible light.

Photocatalysts based on zinc hydroxide and a solid solution of CdS and ZnS were prepared the precipitation method and used for photocatalytic hydrogen production from aqueous solutions of inorganic (NaS/NaSO) and organic (ethanol) sacrificial agents. The photocatalysts were tested in cyclic experiments for hydrogen evolution and studied using X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy, high-resolution transmission electron microscopy (HRTEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) techniques. Different transformations of the β-Zn(OH) co-catalyst were observed in the presence of inorganic and organic sacrificial agents; namely, ZnS was formed in NaS/NaSO solution, whereas the formation of ε-Zn(OH) was detected in solution with ethanol.
