Abstract

The invention provides a method for preparing carbon-based fuel, comprising: combining one or more of plastic products and plastics with Nb 2 o 5 The ultra-thin flakes are dispersed in water and irradiated with sunlight at normal temperature and pressure to obtain carbon-based fuels; the Nb 2 o 5 Ultrathin flakes for complete Nb 2 o 5 Ultrathin flakes or oxygen-defect-rich Nb 2 o 5 ultra-thin slices. This application also provides complete Nb 2 o 5 Preparation method of ultrathin flakes and Nb rich in oxygen vacancies 2 o 5 Method for the preparation of ultrathin sheets. This application discloses for the first time a carbon-based carbon-based composite material produced by photocatalytic conversion of a series of plastics (such as polyethylene, polyvinyl chloride, polypropylene, plastic bags, food preservation film, and disposable lunch boxes) in a normal temperature and pressure and pure water system. New methods of fuel application.

Description

technical field [0001] The invention relates to the technical field of recycling plastic products, in particular to a method for preparing carbon-based fuel and Nb 2 o 5 Method for the preparation of ultrathin sheets. Background technique [0002] Plastic products such as plastic bags, food preservation film and disposable lunch boxes have been widely used in people's production and life due to their advantages of low price, convenient processing, and light texture, but the plastic products after use are discarded in nature to form "White pollution" not only affects the ecological balance, but also threatens human health. In addition to degrading under special conditions, these waste plastic products are very slow in light and biodegradation in the natural environment, and it may take hundreds of years to completely disappear, although they can be disposed of by burial, incineration, etc. , but these methods have serious drawbacks. However, plastic waste is also a potent...
