用连续化学气相法制备具有三种孔隙率特征的材料。多步骤形成机制涉及一个临界温度梯度，并在几秒钟内发生。与由致密纳米颗粒构建的材料相比，所得到的中空气凝胶材料显示出作为气体传感器的优越性能。
The preparation of materials characterized by three types of porosity could be prepared by a continuous chemical gas-phase method. The multistep formation mechanism involves a critical temperature gradient and occurs within seconds. The resulting hollow aerogel materials show superior properties as gas sensors in comparison to materials constructed from compact nanoparticles.
