Fig. 7From: Eco-friendly approach to access of quinoxaline derivatives using nanostructured pyrophosphate Na2PdP2O7 as a new, efficient and reusable heterogeneous catalystEDS spectrum of Na2PdP2O7 (red square indicates the location of EDS analysis). The result in atomic % is as follow: Na: 17.26; Pd: 7.60; P: 17.54; O: 57.60Back to article page
