摘要: 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.

摘要: In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

摘要: A water electrolysis cell includes an electrolyte membrane that is sandwiched between two catalyst layers, the two catalyst layers, two microporous layers each of which is disposed adjacent to a surface of each of the catalyst layers opposite to the electrolyte membrane side, two gas diffusion layers each of which is disposed adjacent to a surface of each of the microporous layers opposite to the catalyst layer side, and two separators each of which is disposed adjacent to a surface of each of the gas diffusion layers opposite to the microporous layer side. In the water electrolysis cell, an area of one of an oxygen electrode and a hydrogen electrode is smaller than an area of the other, and adhesion strength between each of the microporous layers and each of the catalyst layers is higher than that between each of the gas diffusion layers and each of the microporous layers.
