Recent advances in hydrogen generation process via hydrolysis of Mg-based materials: A short review

MnO2/Carbon Composites for Supercapacitor: Synthesis and Electrochemical Performance

“…The development and utilization of eco-friendly renewable energy become an extremely imminent task all over the world. In the past decade, solar, hydro, wind, and tidal energy and other renewable energy sources have greatly alleviated serious problems in the energy and environmental fields (Yang et al, 2011;Xie X. et al, 2019). However, abundant and clean renewable energy mentioned above cannot be widely applied directly owing to the limitation of natural conditions and the poor tunability and stability of generating electricity.…”

Production of High‐Purity Hydrogen and Layered Doubled Hydroxide by Hydrolysis of Mg‐Al Alloys

“…Clean energy and clean water are essential for sustainable societies while the sustainability of our world has faced a great challenge by environmental pollution, primarily due to consumption of fossil fuels 1. Hydrogen energy was proposed to address the pitfalls of fossil energy in the 1970s 2 but the safety concern of transportation and storage of hydrogen has been one of the key issues for its use 3.…”

“…To overcome this problem, high NaOH concentrations 13, 14 and alloying Al with other electrochemically noble metals (Ga, Li, Bi), common transition metals (Fe and Cu) 9, 12, 15–19 and alkaline earth metals (Ca and Mg) 20–22 are employed to promote the hydrolysis reaction. However, the formation of Al(OH) 3 and Mg(OH) 2 films hinders the hydrolysis reaction 1, 23, and the recycled use of solid hydrolysis products could be problematic due to doped metals. The latter problem has been ignored in the literature and clearly, this practice does not fit with the concept of green and sustainable development.…”

The hydrogen storage properties of MgH2–Fe7S8 composites

“…Due to the global ecological issues related to the excessive emissions of greenhouse gas and the huge burning of the fossil materials, which drive us to centered on the alternative energy sources that can be extensively developed and widely used. [1][2][3][4] Meanwhile, hydrogen energy is deemed as one of the most potential ideal energy alternatives on account of its high energy density and with a concept of clean and environmentally friendly natures. [5][6][7][8] However, the practical application and popularize of hydrogen has yet hindered by numerous complicated technical hurdles.…”
