Autor: Juan M. Coronado, Fernando Fresno, Prabhas Jana, Patricia Reñones, David P. Serrano, V.A. de la Peña O'Shea

Publikováno v: Photochemical & Photobiological Sciences. 16:17-23

The activity of NaNbO3 and NaTaO3 perovskites for the photocatalytic reduction of CO2 is studied in this work. For this purpose, sodium niobate and tantalate have been prepared using solid-state reactions, extensively characterised by means of powder
