Design of green high‐energy‐density materials as powerful as the well‐known H 2 /O 2 and N 2 H 4 /O 2 systems is a never‐ending goal. Here, we study the energetic properties of reactions of silanes with oxygen (and gaseous water) by the bond energy procedure and high‐level quantum chemistry calculations. The silanes/oxygen/(water) reactions finally lead to the green products, namely silica and water or silicic acids that exist in nature. The energy densities of these systems with respect to silica and water are higher than those of the conventional H 2 /O 2 and N 2 H 4 /O 2 systems. Their energy densities with respect to silicic acids are also higher than or comparable to that of the N 2 H 4 /O 2 system. We propose that silanes/oxygen/(water) could be powerful green high‐energy‐density materials. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
