Hydrothermal-treated Pt/AlO as an excellent catalyst for toluene total oxidation.

The preparation of highly active supported noble metal catalysts with a low noble metal loading has always been the ultimate goal of researchers working on catalysis. Hydrothermally treated Pt/AlO (Pt/AlO-H) exhibits better catalytic activity than that (Pt/AlO-C) treated via the conventional calcination approach. At the high space velocity of 100,000 mL/(g∙hr), the temperature that correspond to 50% toluene conversion (T) of Pt/AlO-H is 115°C lower than that of Pt/AlO-C, and the turnover frequency (TOF) value can reach 0.
