Zero valent iron (ZVI) and ZVI-based materials have been widely used for the reduction of
nitrate, a major contaminant commonly detected in groundwater and surface water. The …

Photocatalytic water-splitting technology by using nano-sized TiO 2 can produce low cost
and environment-friendly hydrogen using renewable resource such as solar energy, which …

Glycerol is a highly versatile molecule because of its three hydroxyl groups and can be
transformed to a plethora of different value-added fine chemicals and products. It is an …

Photocatalytic water splitting is a sustainable technology for the production of clean fuel in
terms of hydrogen (H2). In the present study, hydrogen (H2) production efficiency of three …

This work aimed to study a pilot-scale sulfur-limestone autotrophic denitrification biofilter
(SLADB) to remove nitrogen from municipal tailwater. The capacity of nitrogen removal and …

Environmentally friendly electrochemical reduction pathways from NO 3− to NH 3 or N 2
