The electrochemical oxidation of LazCu04 in alkaline solution ( 1N KOH) has been used for preparing the superconducting phase La2CuOq+d (6-0.07). Crystallographic data show an enhanced orthorhombic distortion and an increase of the unit cell volume. The transport properties reveal a sharp transition
