Abstract
The selective catalytic reduction of p-nitrophenol (PNP) to p-aminophenol (PAP) not only mitigates the toxicity of industrial wastewater but also enables resource recovery, representing a promising strategy for sustainable pollutant treatment and wastewater purification. In this study, a zinc-doped cobalt oxide catalyst synthesized via a one-step hydrothermal method was applied to the selective reduction of PNP to PAP. The catalyst demonstrated complete PNP degradation (100%), full selectivity toward PAP (100%), and excellent stability. Isotope tracing experiments were conducted to address the debated issue about the source of activated atomic hydrogen (H*) in the selective reduction of PNP. The results…
