WebThe results show that both Pt and Pd have poor selectivity toward any gas at room temperature (RT). This is consistent with experimental reports that selectivity can be achieved only at high temperatures (e.g., T ≈ 400 oC in case of Pt catalyst). On the other hand, the selectivity towards H2S can be achieved using either Ag or Au and towards ... WebApr 7, 2024 · ASK AN EXPERT.
