Abstract
We report on the photocatalytic hydrogen production of Pd/CdS photocatalyst using an unconventional batch process with passive mixing. The catalyst has been characterized using X-ray diffraction and Scanning electron microscope. The result reveals that particle size 3.7 µm. The feasibility studies were carried out by varying the treatability parameters and it was found that maximum hydrogen production occurs at their respective optimum values. The highest volume of hydrogen produced after optimization is 80 mL at 250 W/m2 light intensity, 0.2 M sulphide concentration, 0.2 M sulphite concentration, 10 pH, 300 mL photolyte volume, 0.5g catalyst dosage and 30mL/hr recycle flow rate. Close investigation revealed that this high production is due to the optimization of parameters coupled with batch process with passive mixing. The catalyst also has proved to be photo stable for up to 5 trials
