Solar saline water splitting is a promising approach to sustainable hydrogen production, harnessing abundant solar energy and the availability of brine resources, especially in the Atacama Desert. Bischofite salt (MgCl·6HO) has garnered significant attention due to its wide range of industrial applications. Efficient hydrogen production in arid or hyper arid locations using bischofite solutions is a novel and revolutionary idea. This work studied the electrochemical performance of MnO electrodes using a superposition model based on mixed potential theory and evaluated the superficial performance of this electrode in contact with a 0.5 M bischofite salt solution focusing on the hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR) that occur during saline water splitting. The application of the non-linear superposition model provides valuable electrochemical kinetic parameters that complement the understanding of MnO, this being one of the novelties of this work.

Newly formed playas, such as those resulting from the desiccation of Lake Urmia (LU) in northwest Iran, are significant global dust sources with implications for human health and the environment. Stabilizing these surfaces affordably can be achieved using locally sourced magnesium-enriched brine. To evaluate this approach, for LU playa, we examined the accumulation of ions, minerals deposition, and salt crust (Cr) formation in LU brine under both natural and laboratory conditions.

MgO has broad application potential in CO capture at intermedium temperatures. In this paper, the effects of NaNO doping on the properties of MgO prepared by using waste bischofite as the raw material were investigated to improve the performance of the CO capture. MgO-doped NaNO exhibited excellent CO capture performance at 320 °C with a maximum adsorption capacity of 36.

Currently, the traditional magnesium oxide production process is facing exceptional challenges arising from carbon emission restrictions and environmental protection. Waste bischofite pyrolysis has attracted much attention as a promising technology to address these challenges. Nonetheless, this process has primarily been demonstrated on a laboratory scale, with limited studies on an industrial scale.

The evaporation of seawater in arid climates is currently the main accepted driving mechanism for the formation of ancient and recent salt deposits in shallow basins. However, the deposition of huge amounts of marine salts, including the formation of tens of metres of highly soluble types (tachyhydrite and bischofite) during the Aptian in the South Atlantic and during the Messinian Salinity Crisis, are inconsistent with the wet and warm palaeoclimate conditions reconstructed for these periods. Recently, a debate has been developed that opposes the classic model of evaporite deposition and argues for the generation of salt by serpentinization.
