Abstract

The invention discloses a method for preparing silver oxide-doped manganese oxide nanowire network based on electrospinning and its application in catalytic decomposition of formaldehyde. The method comprises the following steps: Step 1: Mn(CH 3 COO) 2 The solution is added to the PVA solution at room temperature, and magnetically stirred at room temperature to obtain an electrospinning precursor solution; Step 2: Use the electrospinning precursor solution to push the syringe piston through a syringe pump to perform electrospinning; Step 3: Spinning The finished samples are first placed in high-temperature air for high-temperature calcination, and then KMnO 4 Soak the nanowire network obtained by solution immersion method; step 4: drop the silver nanowire dispersion liquid on the nanowire network, then dry it, and use oxygen plasma to treat the sample after the silver nanowire is dropped, and then realize the silver oxide nanowire network. line doping. The invention requires simple equipment, safe and convenient connection process, short preparation period, realizes the doping of silver oxide, and improves the catalytic effect.

Description

technical field [0001] The invention belongs to the field of nanomaterial manufacturing, and relates to a method for preparing silver oxide-doped manganese oxide nanowire network based on electrospinning and its application in catalytic decomposition of formaldehyde. Background technique [0002] The problem of indoor air pollution caused by formaldehyde is becoming more and more serious, and how to efficiently remove formaldehyde has become a major research hotspot. Nowadays, a series of studies on catalytic degradation of formaldehyde have been carried out in the world, mainly including two categories: recovery method and decomposition and purification method. Among them, the recovery method separates formaldehyde from the gas to obtain a higher concentration of formaldehyde, which is then used in industrial production, but the cost of the recovery method is high and it is easy to cause secondary pollution during the treatment process. The decomposition and purification m...

Problems solved by technology

The manganese oxide nanowire network obtained by pure electrospinning method often has a low long-diameter ratio, resulting in insignificant catalytic effect on formaldehyde. However, how to improve the catalytic effect of manganese oxide on formaldehyde has become the focus of research by researchers in this field.
