Defect-engineered loosely stacked Pd/CeO 2 lamellar nanodisks with interfacial synergy for highly sensitive methane detection

Mingwei Ji, Jianwang He, Yuyu Wei, Jing-Jing Tang, Hu Meng, Liang Feng

Loosely stacked lamellar 0.6Pd/CeO 2 was prepared by hydrothermal synthesis followed by Pd impregnation. The resulting sensor shows a response of 3.45 to 10 ppm CH 4 at 260 °C, an 80 ppb theoretical LOD, good selectivity, and long-term stability.
