Zinc oxide/carbon xerogel composites for photocatalytic applications developed through acidic and alkaline synthesis routes: structural, morphological, and photocatalytic evaluations

This paper evaluates the influence of synthesis route (acidic or alkaline) on the structure, morphology, and photocatalytic properties of ZnO/Carbon xerogel composites. Structurally, both classes of materials present the wurtzite phase of zinc oxide. Composites derived from acidic route displayed facile thermal degradation of the zinc oxalate precursor when compared with pure zinc oxalate. Morphology-wise, materials produced through alkaline...
