ABSTRACT:
A photocatalytic reactor to recover precious metals, useful metals, and toxic metals from industrial waste streams using visible or ultraviolet light and semiconductor material as the photocatalyst. Seeds of metal in the same metal group as the metals being recovered are implanted in the reactor to create nucleation sites for the deposition, agglomeration, and growth of the metals being recovered. The reactor may have internally reflective surfaces to effectively multiply the light sources. The input waste stream may be mixed with reaction acceptor materials that reduce electron-hole recombination and that increase reaction rates.
