AB  - An easy way has been practical to make nano-Germanium oxid (GeO<SUB>2</SUB>)/SBA-15 composites by damp impregnation of GeCl<SUB>2</SUB> by means of SBA-15 as the nanoporous sensor support. Following integration SBA-15 with GeO<SUB>2</SUB>, the mesoporous array of SBA-15 could still be well upholder. The sensor prepared of the nano-GeO<SUB>2</SUB>/SBA-15 composite display advanced sensitivities and the sensitivity to 1000 ppm of H<SUB>2</SUB> could be higher than 1300 which is almost 35 times extra sensitive than that of pure GeO<SUB>2</SUB> sensor. This judgment provides an inexpensive and effectual method to apply nanoporous materials to outstandingly improve the sensitivity of semiconductor metal oxide gas sensors.
