0-D to 1-D engendering in PbCrO4 nanostructures and their visible light enabled photocatalytic H2S splitting
Developing the stable semiconducting oxides which are active in the visible region for photocatalytic reactions is a major technological challenge. Herein, we report the facile co-precipitation based synthesis of PbCrO4 nanostructures with an aim to study their hitherto unreported hydrogen production potential. It has been observed that monoclinic PbCrO4 nanorods have been generated using the simple co-precipitation method in the presence of water and methanol as solvents while ultrasonication assisted co-precipitation method produced spherical nanostructures. The nanorods synthesized by aqueous co-precipitation method have yielded highest rate of hydrogen production (3214 µmolh-1 0.5g-1) by splitting hydrogen sulfide (H2S) gas.
