Special Issue Information

Dear Colleagues,

Bismuth, known to be an environmentally benign element, has been used in a growing number of applications over the last few years. The low toxicity of bismuth salts, associated with low cost, make them attractive and practical catalysts. During the last decade, the chemical community finally began considering bismuth catalysts. Now, many academic groups around the world are entering the area. As a result of the increasing concern about green catalysts, bismuth catalysts have become the main focus. These materials fulfill the requirements of being composed of abundant and non-toxic elements, and therefore can be considered environmentally friendly functional materials. The specific applications that will be covered are energy-harvesting devices including solar cells, electrochemical energy storage devices (such as batteries and supercapacitors), and photocatalysts for solar hydrogen production. Photocatalysis is an effective way to solve environmental pollution and energy shortage issues. Among different photocatalysts ( semiconductor), Bi-based photocatalysts have become one of the most popular research topics due to their suitable band gaps, unique layered structures, and physicochemical properties (which can be applied to hydrogen production; denitrification; CO2 reduction; and the degradation of dyes, alcohols, heavy metals, and other pollutants).

In this Special Issue, we wish to cover the most recent advances in all these aspects of bismuth-based catalysts by hosting a mix of original research articles and short critical reviews.

Photoelectrochemical (PEC) water splitting is an eco-friendly method for producing clean and sustainable hydrogen fuels. Compared with the fabrication of solar hydrogen using n-type metal oxide semiconductor photoanodes, that of solar hydrogen using p-type metal oxide semiconductor photocathodes has not been researched as thoroughly. Therefore, this study investigated the effect of drop casting time on the PEC performance of a prepared CuBi2O4 photocathode. XPS, HRTEM, UV-DRS, Raman spectroscopy, XRD, and SEM analyses were used to characterize the prepared CuBi2O4 photocathode. Owing to the high charge separation and transfer, the photocurrent density of the CuBi2O4 photocathode was ~0.6 mA cm−2 at 0.3 V vs. RHE. The nanoporous CuBi2O4 photocathode exhibited a high photocurrent density of up to 1.2 mA cm−2 at 0.3 V vs. RHE with H2O2 as a sacrificial agent. Mott–Schottky and impedance measurements were also performed on the CuBi2O4 photocathode to estimate its acceptor density and charge-transfer resistance. Full article
