摘要：
A versatile SnO2@graphene nanocomposite with a mesoporous structure was prepared by a facile and green solvothermal method. The nanocomposite exhibited high response to low-concentration HCHO (1 ppm) at low working temperature (120 degrees C). The response and recovery times are 1 s and 85 s for 1 ppm formaldehyde. There is an excellent linear relationship (R = 99.798%) between response and the concentration of HCHO in a large range (1-100 ppm).
