Resumen de: EP4417733A1
This invention discloses a method, device, and system for the direct electrolysis of seawater without desalination for hydrogen production. By immersing the direct electrolysis device for hydrogen production from seawater without desalination directly into seawater, driven by the pressure difference at the interface between seawater and the self-driven electrolyte, seawater continuously enters the device through the solution mass transfer layer. The self-driven electrolyte induces the water to enter the electrolyte solution, while the hydrophobic action of the solution mass transfer layer effectively blocks non-water impurities in the solution. During electrolysis, the water in the self-driven electrolyte is consumed to produce hydrogen and oxygen, inducing the regeneration of the electrolyte, maintaining the pressure difference at the interface, and achieving a self-circulating excitation drive without additional energy consumption. When the amount of water solution induced by the self-driven electrolyte equals the amount of water consumed for hydrogen production, a dynamically stable and energy-efficient method and system for the direct electrolysis of seawater without desalination for hydrogen production are formed.

A photoelectrode includes a double-layer homojunction of metal oxide semiconductor films without heteroatoms incorporated. The metal oxide semiconductor films are uniform in large size with rich oxygen vacancies. For BiVO4 films, Bi precursor can be electrodeposited on a substrate under atmospheric pressure and air atmosphere. The electrolytes for electrodeposition are acidic or alkaline with controllable pHs. The electrodeposited substrate is transferred to the muffle furnace for thermal evaporation with V precursor. Film thickness and size can be controlled by electrodeposition parameters. The BiVO4 double-layer homojunction is a safer and cheaper material in photo-driven devices, hydrogen producers, and solar cells, and is an economical replacement of costly III-V compounds, polymers, and valuable fossil. The BiVO4 double-layer homojunction can also be employed as photoelectrodes for H2 production via photoelectrochemical (PEC) water splitting under solar light, which can provide pivotal reactor materials for hydrogen producers and solar cells.
