PNNL researchers have also discovered that silver hollandite is an excellent low-temperature sulfur oxides absorbent. Unlike most oxidation catalysts, which can be easily poisoned by sulfur oxides, silver hollandite maintains its catalytic activity even while it ages by absorbing sulfur oxides.
Pacific Northwest National Laboratory researcher Liyu Li will be presenting his results at the 230th national meeting of the American Chemical Society at 6:00 p.m., Wednesday, Aug. 31
