Solid-state sensor nanostructured materials (SnO2, ZnO and CeO2) have been prepared by pyrolysis of macromolecular complexes: PSP-co-4-PVP·(SnCl2) n , PSP-co-4-PVP·(ZnCl2) n and PSP-co-4-PVP·(Ce(NO3)3) n in several molar ratios under air at 800 °C. The as-prepared nanostructured SnO2 exhibits morphologies and particle sizes which are dependent upon the molar ratio of the SnCl2:PSP-co-4-PVP. When a larger weight fraction of the inorganic salt in the precursor mixture is used (1:10 > 1:5 > 1.1) larger crystalline crystals are found for each oxide. For ZnO and CeO2 agglomerates of morphologies from the respective hexagonal and cubic structures were observed with typical sizes of 30–50 nm in both cases for a precursor mixture ratio of 1:1.
