The invention relates to a synthesis method of aluminum fluoride doped graded porous carbon nanofibers for electro-catalysis, and belongs to the technical field of electrode materials. The preparation method comprises the following steps: (1) preparing aluminum sol; (2) preparing a spinning solution; (3) preparing nascent fibers by using an electrostatic dissolving and blowing technology; (4) carrying out pre-oxidation treatment on the nascent fiber to obtain a pre-oxidized precursor nanofiber; and (5) carrying out a carbonization process on the pre-oxidized precursor nanofiber to obtain the aluminum fluoride doped graded porous carbon nanofiber. The invention provides a new strategy for simply and conveniently forming a hierarchical porous structure, and the prepared aluminum fluoride doped hierarchical porous carbon nanofiber has an ultrahigh specific surface area due to the construction of the hierarchical porous structure, so that in-situ grown aluminum fluoride active sites can be ...

The invention relates to a rural toilet excrement-water separation device and method. The main body part of the manure-water separation device comprises a first channel and a second channel, the middle part of the first channel is connected with the second channel below the first channel, and a filter screen is arranged at the junction of the first channel and the second channel to communicate the two channels; a slag outlet is formed in the tail end of the first channel; a water outlet is formed in the tail end of the second channel. When excrement and flushing water pass through the excrement-water separation device, liquid such as the flushing water and urine is filtered by the filter screen in the device and flows out of the water outlet, solid such as the excrement is discharged from the slag outlet, and therefore the excrement-water separation effect is achieved. According to the device, the gravitational potential energy of excrement and flushing water and kinetic energy generated ...
