TL;DR: In this article, the NH3-N was removed from the water by using a Z-scheme photocatalytic system, and the results showed the rate constant of NH3−N conversion on it was 0.705h−1, 1.7 times as high as that on g-C3N4/TiO2, and most of the NH 3−N were converted into gaseous products.

TL;DR: In this article, the g-C3N4(Ag)/Gr/TiO2 Z-scheme photocatalyst was successfully prepared by hydrothermal method and the results showed that the nanocomposite was constructed.

Abstract: The invention relates the field of organic fertilizers and in particular relates to a mycorrhiza-assisted soil ecological repair organic fertilizer and a preparation method thereof Raw materials of the organic fertilizer comprise the following substances in parts by mass: 30-40 parts of humic acid, 30-40 parts of humus, 5 parts of plant ash, 2-5 parts of nitrogen, 5-10 parts of phosphorus, 3-5 parts of potassium, 5 parts of silicate and 2-10 parts of mycorrhiza fungi By taking humic acid and humus as a substrate and adding element components such as nitrogen, phosphorus and potassium required by crops, the organic fertilizer not only has the advantages of rich nutrient type and long and stable fertilizer efficiency, but also directionally supplements special nutrients required by crops, and meanwhile, the organic fertilizer can repair soil damaged by inorganic fertilizers, and has a good ecological benefit

TL;DR: In this article, a polyvinylpyrrolidone coated nanometer WO3 (PVP@WO3) is presented, which is a 100-250nm nanocube with a PVP organic thin layer.
