SUMMARY:

The need for new fuel sources, coupled with the clean means of production development, has increased the interest of scientists in recent decades. Among the known technologies, hydrogen production from water is potentially interesting. Highlighted since 1970, it involves the water breakdown through photocatalysis that can be coupled to its electrochemical degradation, giving access to a hybrid photoelectrochemical process, completely clean, with zero carbon emissions. This idea has been revived in recent years due to advances in materials science and the optimization of reaction systems. Based on this, the purpose of this doctoral thesis project is to develop materials: pure sodium niobate (NaNbO3) and combined with molybdenum disulfide (NaNbO3/MoS2), for hydrogen generation from photo-electro-catalytic processes: Electrocatalysis, photocatalysis and photoelectrocatalysis. This heterojunction for hydrogen evolution purposes has been reported only once in the literature, with a synthesis methodology completely different from that proposed in this work, making it unpublished and innovative, giving the present work scientific and technological relevance.
