  • Nanocomposite for photocatalytic Hydrogen production and method for its preparation
    Patent number: 8207081
    Abstract: A novel M—Pd—Cr2O3 (M?Pt, Ru, Rh, Os, Au and Ag) nanocomposite cocatalysts and its preparation method. The cocatalysts loaded on CdS photocatalyst enhances the photocatalytic activities toward H2 evolution from aqueous solutions (NH4)2SO3, a regenerable electron donor, under sunlight radiation. An embodiment provides a new and facile method and system for the preparation of M—Pd—Cr2O3 nanocomposite cocatalysts at room temperature. Pd—Cr2O3 loaded CdS photocatalyst has higher hydrogen evolution activity than that of a plain Pd metal loaded CdS and its performance is comparable to that of Pt/CdS photocatalyst. Formation of a Pd—Cr2O3 composite with reduced size of nanoparticles results in an increase in the photocatalyst activity for H2 evolution.
