Abstract

The invention relates to a ship tail gas sensing material and a preparation process thereof. The preparation process comprises the steps of: growing large-area graphene on the surface of copper foil by utilizing a furnace tube by means of high-temperature pyrolysis under a fixed flow; and transferring the double-layer graphene onto a silicon substrate by adopting a bubble template method. The shiptail gas sensing material has large sensing contact area for gas molecules, is a gas sensor with great potential, is convenient in detection, low in cost, precise in numerical value acquisition, stable, reliable and low in manufacturing cost, has remarkably enhanced effect, and further greatly improves the overall efficiency and the operation reliability.

Description

technical field [0001] The invention relates to the field of ship environmental protection, and more specifically relates to a ship exhaust sensing material and a preparation process thereof. Background technique [0002] Among the major transportation modes such as road, railway, water transportation, aviation and pipeline, water transportation has become the main transportation mode of international trade today due to its advantages of large loading capacity, low freight cost and long distance, accounting for about 90% of the total international cargo transportation. left and right share. Compared with motor gasoline and diesel oil, the product quality of marine fuel oil is far lower at present. Since most ships are not equipped with exhaust gas treatment facilities, combustion exhaust gas is directly discharged into the environment, which has a great impact on air quality. [0003] As a new type of carbon nanomaterial, graphene-based materials have the characteristics o...
