Abstract A large quantity (2.5–3 in molar ratio) of NO was taken up from gas phase by YBa2Cu3Oy (y=6.88) at 573 K, and desorbed mostly as NO at 773 K. The rate of uptake at 573 K increased with the increase in the concentration of coexisting O2 upto 8%, or by treating the sample in N2 above 850 K. The addition of Pd (0.1%) to YBa2Cu3Oy greatly accelerated the rate of NO uptake.
