A hydrogen-generating substance that reacts with moisture (liquid water or water vapor) in a medical substance or moisture in air introduced into a medical container is kneaded into an exterior sheet 40 of the medical container that encloses the medical substance therein. The medical container can be a bag-shaped medical container, a tube-shaped medical container, a medical container with a sealing fastener or the like. The medical substance containing moisture can be blood, an injection solution, a drug solution, a nutrient solution, a replenishment solution (an infusion solution), an instillation solution or the like. A solid preparation is preferably enclosed within the medical container with the sealing fastener. For example, the hydrogen-generating substance to be kneaded can be metal magnesium and is preferably fine-powdered ceramics obtained by firing the mixture of a hydrogen-generating substance and a mineral substance such as calcium.

The invention is a method for coproducing Hydrogen and certain metals by reducing a metal oxide(s) with MgH.sub.2 or with metal and water, wherein the non-water oxides used in the method include SiO.sub.2, Cr.sub.2O.sub.3, TiO.sub.2, SnO.sub.2, ZrO.sub.2, CuO, ZnO, WO.sub.3, Ta.sub.2O.sub.5, Cs.sub.2Cr.sub.2O.sub.7 or CsOH. The method reacts the MgH.sub.2 with a metal oxide or directly uses metal and water instead of a hydride, and initiates a reaction with the metal oxide. The reaction releases Hydrogen and reduces the subject oxide to metal.

Disclosed herein are aluminum oxide aerogels and methods of making and use thereof. The methods of making the aluminum oxide aerogel include contacting a solid comprising aluminum with a Ga-based liquid alloy to dissolve at least a portion of the aluminum from the solid, thereby forming an aluminum-alloy mixture; and contacting the aluminum-alloy mixture with a fluid comprising water, thereby forming the aluminum oxide aerogel. In some examples, the methods can further comprise capturing and converting carbon dioxide to a syngas comprising carbon monoxide and hydrogen.
