Facile route fabrication of nano-Ni core mesoporous-silica shell particles with high catalytic activity towards 4-nitrophenol reduction

Microwave-assisted synthesis of L-cysteine-capped nickel nanoparticles for catalytic reduction of 4-nitrophenol

“…This suggests that the heterogeneous reduction of 4-NPh in our case is a surface phenomenon. The obtained activation energy is much smaller than that reported by several other studies [44][45][46], which may be attributed to the larger surface area provided by the smaller size of synthesised Ni NPs.…”

A new visible light active multifunctional ternary composite based on TiO2–In2O3 nanocrystals heterojunction decorated porous graphitic carbon nitride for photocatalytic treatment of hazardous pollutant and H2 evolution

“…The specific surface areas, pore sizes and pore volumes data of the as-prepared catalysts calculated by BET and BJH methods were summarized in Table 1. All the g-C 3 N 4 based photocatalysts are type IV with H3 hysteresis loops according to the IUPAC classification, indicating the presence of mesopores [71][72][73][74]. As shown in Table 1, the pure g-C 3 N 4 showed a BET surface area of ∼49.5 m 2 /g.…”

Basic concepts and recent advances in nitrophenol reduction by gold- and other transition metal nanoparticles

“…Other metallic NPs such as Pt [108] Ni [143], Zn [144], Co [145] and Ru [146] NPs (or their alloy NPs) are also involved in the 4-NP reduction. Their apparent rate constant together with PdNPs, AgNPs and CuNPs are collected in Table 2.…”
