Photocatalytic degradation and upcycling of nitrate-rich textile wastewater to ammonia over a tandem reactor.

ABSTRACT: Textile is one of the industrial sectors producing multiple types of polluting substances, including dyes and nitrate. Lately, the realization of pollutant degradation through electrochemical treatment has been applied more commonly. However, in textile wastewater a high level of organic dyes can inhibit the electrocatalytic reduction of nitrate. Hence, we construct a tandem reactor to synchronously remove the organic dyes and nitrate contaminants as well as yield the value-added ammonia product from the simulated textile wastewater. The tandem reactor shows impressive efficiency towards photocatalytic decomposing methylene blue (MB), methyl orange (MO) and methyl violet (MV) (~ 100%) coupled with NO₃^--to-NH₃ conversion (maximum NH₃ evolution val
