Zusammenfassung:	The effect of neodymium addition in the composition of complex bismuth cuprates Bi 2 Sr 2–x N dx CaCu 2 O y (0 ≤ x ≤ 0.1) on their structural and electrophysical characteristics and catalytic properties is found. It is established that increase in the neodymium content is accompanied by antibate (inverse) change in the unit cell parameters, increased structural defectiveness, and slight increase of the superconducting temperature. The increased activity of the Nd-substituted cuprates in the oxidation of CO is due to increase in the defectiveness of the structure and the content of mobile oxygen in the crystal lattice.
