Procedure

The nano ZnO (as described above) is further treated for the preparation of a photocatalyst of the present invention. The method include mixing a pre-determined amount of palladium(II) nitrate dihydrate (Pd(NO3)2.2H2O) in deionized water 414 to form enough solution to cover the required amount of nano-ZnO powder and form palladium nitrate impregnated nano-ZnO 416. The palladium nitrate impregnated nano-ZnO was then dried at heating rate of 1° C./min from room temperature up to 100° C. 418 and then exposed to ammonia vapors for another 10 min 420. This step is performed to avoid melting of palladium nitrate before decomposition resulting in high dispersion of nano Pd particles on ZnO. The palladium nitrate impregnated nano-ZnO was then dried overnight in air at a temp of 110° C. 422. The dried palladium nitrate impregnated nano-ZnO was calcined at 500° C. for 3 hours at a heating rate of 1.5° C./min to obtain a Pd-nano ZnO photocatalyst 424 (FIG. 1).
