摘要: Abstract A series of novel nitrided tantalophosphates has been prepared by nitridation X-ray amorphous TaPO 5 precursors under ammonia flow. By varying the temperature, 5− x N 2 /3 (1.6   g −1 , (ii) yellow to orange colors depending on nitrogen contents and (iii) formation a solid solution with variable oxygen contents. The corresponding oxynitrides have characterized several techniques including diffraction, oxygen/nitrogen elemental analyses, BET analysis, UV–vis spectrophotometry, thermal SEM, DRIFT NMR analyses.
