Abstract: An explosive composition comprises a porous fuel and an oxidizer. The porous fuel is a solid with a structure size measuring between about 2 nm and 1000 nm and has a porosity that lies between 10% and 98%. The oxidizer is solid or liquid at room temperature and is incorporated into the pores of the porous fuel. The oxidizer is selected, in an amount of at least 50% by weight relative to a total quantity of the oxidizer, from the group consisting of hydrogen peroxide, hydroxyl ammonium nitrate, organic nitro compounds or nitrates, alkali metal nitrates or earth alkali metal nitrates as well as metal nitrites, metal chlorates, metal perchlorates, metal bromates, metal iodates, metal oxides, metal peroxides, ammonium perchlorate, ammonium nitrate and mixtures thereof.
