Abstract

The invention relates to the technical field of photocatalysis, in particular to an iron-doped defect-rich carbon nitride nanotube photocatalyst and a preparation method and application thereof. The preparation method comprises the following steps: firstly, obtaining a modified intermediate through a hydrothermal method, and then calcining the modified intermediate through a muffle furnace to obtain the defect-rich carbon nitride nanotube with a porous structure. The problems that an existing photocatalyst is not high in visible light utilization rate, poor in nitrogen adsorption and activation capacity, low in nitrogen fixation synthesis efficiency and the like are solved by utilizing active sites caused by the porous structure and iron element doping.

Description

technical field [0001] The invention relates to the technical field of photocatalysis, in particular to an iron-doped defect-rich carbon nitride nanotube photocatalyst, a preparation method and an application. Background technique [0002] The photocatalytic technology driven by sunlight has attracted extensive attention of scientific researchers because of its environmental protection and help to alleviate the current energy pressure. Graphite carbon nitride (g-C 3 N 4 ) self-applied to photocatalytic reactions, has been applied in many fields. However, there are still many parts to be improved, such as too small specific surface area, high photogenerated carrier recombination rate, slow photogenerated electron transport rate, etc., resulting in low photocatalytic performance. [0003] Industrial nitrogen fixation is considered unsustainable due to its high energy consumption and carbon dioxide emissions. Light-driven nitrogen fixation only needs to use water and nitroge...
