Abstract
Conference Title: 2014 IEEE International Conference on Oxide Materials for Electronic Engineering (OMEE) Conference Start Date: 2014, May 26 Conference End Date: 2014, May 30 Conference Location: Lviv, Ukraine The Ag2Nb4O11 (space group R3c, a = 6.1521(3) [Angstrom], c = 37.0455(7) [Angstrom]) and Ag2Ta4O11 (space group R-3c, a = 6.21021(5) [Angstrom], c = 36.8708(3) [Angstrom]) were prepared by conventional solid-state reaction. Their optical absorption, photocatalytic activity and electronic structure are reported.
