摘要：
Materials with porous and hierarchical structures are of great interest for potential use in energy and environmental applications. Here, we fabricate the WO3 microspheres which consist of the nanosheets by using a simple hydrothermal process. The likely formation mechanism of the porous microspheres is proposed based on the time-dependent experiments. As a consequence of the unique hierarchical and porous architecture, the microspheres show excellent gas sensing properties due to their large amount of petals and pores, which benefited for the gas diffusion.
