Improve the Formaldehyde Gas-Sensing Performance of 3D Porous SnO2 by Controlling the Calcination Time and the Amount of Holmium Doped

Porous SnO 2 with high sensitivity and fast response has attracted much attention. Herein, we prepared 3D porous SnO 2 using carbon balls as a template and studied the effects of sintering time (1 h, 2 h, 3 h, 4 h) at a certain calcination temperature of 500℃ and Ho doping on the gas-sensing perform...
