Facile route to silver submicron-sized particles and their catalytic activity towards 4-nitrophenol reduction

Mechanical properties of nano-silver joints as die attach materials

“…Generally, the Ag nanoparticles of sizes less than 20 nm are precipitated from Ag salts to form agglomerates with sizes ranging from 800 to 3500 nm [31]. Reducing agents like ascorbic acid [40,56], hydrazine monohydrate [57], sodium citrate [58] or sodium citrate dihydrate [59], polyvinylpyrollidone [50], ethylenediaminetetraacetic acid (EDTA) [60], sodium sulfite [61] and sodium borohydride [62] were added into Ag salts like nitrates, sulphates or chlorates or Ag-ammonia complexes [62]. The reducing reaction occurred in a polar solvent such as ethanol, methanol, acetonitrile or tetrahydrofurane [40].…”

Synthesis of CuO@NiO core-shell nanoparticles by homogeneous precipitation method

“…The catalytic reactivity of core-shell and pure metal oxide nanoparticles was studied by the reduction of 4-nitrophenol with NaBH 4 . This reaction has been used to test the reactivity of metal oxide nanoparticles [68,69]. An aqueous solution of 4-nitrophenol is yellow colored which on reduction with NaBH 4 become colorless due to the reduction of 4-nitrophenolate ions (yellow) to 4-aminophenolate ions (colorless) [70].…”

Visible light photo catalytic inactivation of bacteria and photo degradation of methylene blue with Ag/TiO 2 nanocomposite prepared by a novel method

“…Chemical reduction method is the simplest process, widely used to obtain uniform, small size and highly disperse nanoparticles [24]. But chemical reduction method for the syntheses of nanoparticles has a big disadvantage of using toxic chemicals and formation of toxic byproducts, making nanoparticles unsuitable for biological purposes [25][26][27].…”
