Synthesis and high formaldehyde sensing properties of quasi two-dimensional mesoporous ZnSnO nanomaterials.

Quasi two-dimensional (2D) mesoporous ZnSnO nanomaterials (QTMZNS) were synthesized by a simple template-free hydrothermal method. The as-prepared products were characterized by TEM, SEM, XRD, TG/DTA, and FTIR. The results showed that the precursor was a mixture of Zn(OH)(CO) and ZnSnO in the hydrothermal process, and the high purity QTMZNS were obtained by calcination combined with subsequent washing of 20 wt% NHCl solutions.
