Highly Efficient Reduction of 4‐Nitrophenol by Cu Nanoparticle Decorated Graphdiyne

Abstract

Catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) over high-performance and stable metal nanoparticle catalyst is highly desirable. This study experimentally demonstrated that graphdiyne (GDY), an all-carbon two-dimensional material composed of two hybrid carbon atoms (sp and sp 2 ), can uniformly disperse copper nanoparticles through simple microwave reduction and has excellent 4-NP reduction ability.Cu/GDY shows an extraordinary reaction rate constant of 0.9984 min À 1 , Moreover, the catalytic activity is maintained almost intact within five cycles. These encouraging results demonstrated that the unique pores and electronic structure of GDY enhance the stability of anchored metal nanoparticles and have great potential to degrade 4-NP as a promising support for copper nanoparticles.

“… 35 In addition, Cu/graphdiyne material prepared by Li's group also exhibits high catalytic ability for rapid reduction of 4-NP within 3 min. 36 These literature show that the transition metal nanomaterials also have a good catalytic effect on the 4-NP reduction reaction.…”

“…Its solubility in water systems and its stability facilitates its accumulation, causing damage to the blood, kidneys, liver and nervous system of humans and animals [11][12][13]. The United States Environmental Protection Agency (US-EPA) has listed 4-NP as one of the 114 priority organic pollutants and The China National Environmental Monitoring Center considers it a priority control, with 60 ppb being the maximum content of 4-NP in direct drinking water [1,14].…”

“…6,7 Hydrogen is also used in the reduction of several organic compounds, such as hazardous 4-nitrophenol (4-NP), an environmental pollutant, 8 particularly a major contaminant of water resources. 9 Among them, organic wastewater containing 4-nitrophenol has a number of major issues, 10,11 including a protracted period of pollution, a huge amount of discharge, substantial damage, a high level of toxicity, and a treatment process that is incredibly challenging. 4-Aminophenol is the main intermediate for paracetamol, and major commodity chemicals (acebutolol, ambroxol, and sorafenib) used extensively in the production of pharmaceuticals, dyes, and polymers.…”
