SpletBecause the reduction temperature of Pd will not be so high. It ’s more likely, because you ’re using a carbon carrier, methanation process occurs in your exper. You can use TPR … Splet15. maj 2024 · Here, without using any organic stabilizer, via two-steps process, Pd-based catalysts supported on La-modified Al2O3 by a new colloid synthesis method using different reducing reagents were prepared. It was found that the reducibility and structure of reducer controlled the rate of nucleation and growth of Pd in its precursor solution …
