Silver nanoparticles-decorated-Co3O4 porous sheets as efficient catalysts for the liquid-phase hydrogenation reduction of p-Nitrophenol

Two-dimensional MXene enabled carbon quantum dots@Ag with enhanced catalytic activity towards the reduction of p-nitrophenol

“…20 Although nanocomposites have better catalytic properties than NPs, agglomeration occurs during the catalytic process due to their high surface energy, affecting catalytic activity and experimental reproducibility. 21 The newly-fashioned 2D layered inorganic materials, such as silicene, black phosphorus (BP), transition metal oxides (TMOs), graphitic carbon nitride (g-C 3 N 4 ), and MXenes etc., have attracted a lot of attention due to their unique properties and important applications. 22,23 Among these 2D materials, MXene exhibits a unique 2D layered structure with a large specic surface area, good electrical conductivity, mechanical exibility, chemical and thermal stability, environment-friendly characteristics, and other properties.…”

Synthesis of bimetallic Co–Pt/cellulose nanocomposites for catalytic reduction of p-nitrophenol

“…32) fibers, 12 chitosan/agar microcapsules, 33 CeO 2 , 6 and Co 3 O 4 (ref. 34) have been reported as substrates for various catalysts employed for p -NP reduction with NaBH 4 . The literature states that the structural and morphological properties of substrates greatly affect the distribution, size and shape of metal NPs dispersed on the substrate which in turn alters its original catalytic performance.…”

Synthesis of cuprous oxide nanocubes combined with chitosan nanoparticles and its application to p-nitrophenol degradation

“…Thus, p-NP was listed as one of the priority hazardous and toxic pollutants by the U.S. Environmental Protection Agency (EPA) [5]. Various studies have been performed to reduce the content of p-NP in solution, such as photocatalytic hydrogenation [1,6], photoelectrocatalytic [7,8], biological degradation [9], and metal-free catalyst [10]. In recent years, the reduction of p-NP to p-aminophenol (p-AP) has gained attention from the scientific community, since p-AP is a low toxic compound useful as an important intermediate in the preparation of pharmaceuticals, lubricants, and dyes [11].…”
