COUPLED SEMICONDUCTORS AS photo- electrochemical catalyst for water splitting

Hydrogen is a perspective green fuel that produces only water when consumed in a fuel cell. The main method for hydrogen production is electrochemical water splitting. However, the water electrolysis is a rather energy-consuming process. Alternative method of the overall water splitting is photo-enhanced electrolysis under light illumination. The founding or new, photo-and electro-catalytically active materials, able to increase the efficiency of water splitting is a hot topic of actual research. In recent years, 2D materials have been considered as very promising materials for the water splitting. In this work, a hybrid material consisting of 2D WO3-CdS coupled structure is created and introduced in water splitting process. Using the proposed design the high efficiency of hydrogen production can be potentially reached.
