Study on the activating effects of biochar composites on formaldehyde

Abstract

Formaldehyde is ubiquitous and harmful to human body. In this study, biochar graphene and composites are prepared by hydrothermal method. According to the material properties of formaldehyde, biochar composites are used to catalyze the two ends of electrode to promote the activation reaction of formaldehyde. By analyzing the characteristics of Fourier transform infrared spectrum image, it is found that the biochar composite Cu(OH)2/C is more conducive to activate formaldehyde, which effectively improves the conductivity of the material and provides a reference for studying the effects of biochar composites on formaldehyde.
