Dehydrogenation of ammonia borane catalyzed by in situ synthesized Fe–Co nano-alloy in aqueous solution

Synthesis of air stable FeCo alloy nanocrystallite by proteic sol–gel method using a rotary oven

“…The FeCo-based soft magnetic alloys belong to a class of nanomaterials which has some unique features, such as large permeability, high saturation magnetization, and high Curie temperature [2][3][4]. The FeCo alloys are being widely studied due to the great technological importance and their multiple applications, such as the medicine related to cancer treatments [5], the biomedicine to the controlled release of drugs in the body [6], in the catalytic process [7][8][9], in magnetic bearings [10], and thin films [11].…”

NaOH modified P(acrylamide) hydrogel matrices for in situ metal nanoparticles preparation and their use in H2 generation from hydrolysis of NaBH4

“…However, molecular H 2 does not instinctively exist in nature; nonetheless, it can be generated from numerous methods such as hydrolysis of chemical hydrides, steam reforming hydrocarbons, and some H 2 compounds, water electrolysis or by other methods . The chemical hydrides such as NaBH 4 , NH 3 BH 3 , LiAlH 4 , and others are very well known as high hydrogen containing materials . Especially, NaBH 4 has a number of discernible benefits such as the evolving H 2 can be measured readily during the reaction, no toxic waste product and side‐reaction, chemically stable, non toxic nature and high H 2 content .…”

Nanocatalysts for Hydrogen Generation from Ammonia Borane and Hydrazine Borane

“…Bimetallic catalysts usually show improved catalytic performance in comparison to their monometallic counterparts; due to that the metal-metal interactions in the bimetallic systems presumably account for the tuning of the bonding pattern of reactants and stabilization of reaction intermediates on the catalyst surface. A number of bimetallic catalysts [58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73], such as Au-Co [58,59], Au-Ni [60,61], Ru-Co [62], Ru-Ni [63,64], Ru-Cu [62], Pt-Ni [65,66], Pd-Co [67], Cu-Co [68,69], Cu-Fe [70], Fe-Ni [71], Fe-Co [72], and Co-Ni [73], have been employed in the hydrolysis of AB. For example, small Au-Ni and Au-Co NPs (2-4 nm) embedded in SiO 2 nanospheres (about 15 nm) exhibited superior performance in the hydrolysis of AB [58,61], in contrast to monometallic counterparts Au@SiO 2 , Ni@SiO 2 , and Co@SiO 2 .…”
