Nanocrystalline Metal

High surface area and uniform nano-sized TiO2 and ZrO2 were prepared readily by the infiltration of metal alkoxides into the nanoporous SiO2, SBA-15 and the following selective dissolution of SiO2. The obtained particles of TiO2 and ZrO2, 8.1 nm were nanocrystalline of which the structure were anatase and tetragonal, respectively. The surface area and pore volume of the nanocrystalline metal oxides can be increased to above 200 m2g-1 and 0.30 cm3g-1, respectively.

Broad Overview

Perovskites are mixed metal-oxides which have received much attention and more applicative interests in the research field as well as in industry due to their unique properties like high surface area, small size, excellent magnetic property, thermal stability and low price. Perovskites are effectively used as semiconductors, adsorbents, catalyst, Superconductors etc. The present study outlined the broad overview of the Perovskite as photocatalyst.

Fft Analysis

ABSTRACTHybrid porous silicon, consisting of a microporous framework whose walls are covered with a thin nanoporous layer, proves to be an inexpensive and robust platform for fabrication of rapid, reversible, and sensitive semiconductor sensors. An extremely high surface area provides a mechanism for the detection of ppm and ppb levels of a range of gases including ammonia, NOx, and CO. A general method of coating electroless metal onto the surface provides a basis for nanostructure induced selectivity between these gases. Further, the introduction of FFT analysis to the rapidly reversible and linear response of the porous silicon gas sensor allows the gas response to be acquired and filtered on a drifting baseline.
