The removal of NH 4 + ion from aqueous solution using the natural zeolite was studied at pH values 4–9 and the data obtained were given in Fig. 1. The pH of the aqueous solution was found to be an important factor for the exchange of NH 4 + ion by zeolite. The removal efficiency increased by raising the pH from 4 to 8 and reached a …

Due to the complicated storage conditions of coal resources, 95% of the production is through underground mining. The geological structure of the coal mine is complex and natural disasters are serious at the same time, so there are many hidden risks. Therefore, the research on coal mine safety early warning system is of great significance.

In the late 1960s, one of the present authors (AF) began to investigate the photoelectrolysis of water, using a single crystal TiO 2 electrode. Then, the first report on the efficient hydrogen production from water by TiO 2 photocatalysis was published in Nature in 1972, at the time of "the oil crisis" [2].Thus, TiO 2 photocatalysis drew the …
