Abstract

The invention relates to nano-porous copper oxide and a preparation method and application thereof in garbage stink. The preparation method comprises the following steps: stirring an organic copper salt and an aromatic solvent at 60-80 DEG C, mixing to form a first mixed solution, uniformly mixing organic alcohol and water to form a second mixed solution, adding the second mixed solution into thefirst mixed solution, heating to react while stirring, and drying by distillation to obtain a precursor, wherein the aromatic solvent is at least one of benzene, methylbenzene, dimethylbenzene and ethylbenzene, and calcining the precursor to obtain the nano-porous copper oxide. The nano-porous copper oxide prepared by the method disclosed by the invention has certain lipophilicity and has a relatively good adsorption removal effect on sulfur-containing organic compounds when being applied to garbage odor, and the adsorption removal rate reaches 95% or above.

Description

technical field [0001] The invention relates to the technical field of adsorption materials, in particular to a nanoporous copper oxide, a preparation method thereof and an application in garbage odor. Background technique [0002] The odor produced by garbage odor has a lot to do with garbage components, stacking days, anaerobic fermentation, aerobic fermentation and climate. During the anaerobic fermentation process of garbage, a large amount of landfill gas will be produced, and its components are usually about 50% to 70% of methane, about 30% to 50% of carbon dioxide, and about 1% of trace components. Gas is caused by certain substances in this 1% trace component. These trace components include organic compounds and inorganic compounds, with a wide variety and extremely low concentrations. More than 100 substances can be detected in landfills, with concentrations at the ppm or ppb level. Substances with minor components include: sulfur-containing compounds (hydrogen su...
