Reduced Graphene Oxide Supported Bimetallic Cobalt–Palladium Nanoparticles with High Catalytic Activity towards Formic Acid Electro-oxidation

Ultrasound-assisted preparation of PdCo bimetallic nanoparticles loaded on beta zeolite for efficient catalytic hydrogen production from dodecahydro-N-ethylcarbazole

“…The crystallinity of the Pd 1 C 9 /beta catalyst increased due to the shedding of the heterocrystalline phase caused by the ultrasonic process. The characteristic diffraction peaks at 2θ = 40.1°, 46.7°, 68.1°, 82.1° and 86.6° correspond to the Pd (1 1 1), (2 0 0), (2 2 0), (3 1 1) and (2 2 2) crystal planes, respectively, and those at 2θ = 30.1° and 59.6° to the Co (2 0 2) and (4 1 1) crystal planes, respectively [51] , [52] . The characteristic diffraction peaks of Co and Pd were not observed in the XRD patterns of Co/beta, Pd/beta and Pd 1 Co 9 /beta.…”

Recent Advances in Anode Electrocatalysts for Direct Formic Acid Fuel Cells – Part I – Fundamentals and Pd Based Catalysts

“…It showed excellent catalytic activity due to small particle size, and strong synergic interaction between Pd and graphene. [162] Our group recently published PdÀ Co supported on nitrogen doped rGO with high mass activity of 4833.12 mA/mg. [163]…”

Structural analysis of pure PtCu3 nanoparticles synthesized by modified Polyol process

“…Among these synthesis methods and structures, the nanoalloy size is mostly over 10 nm and there are a few studies, which are mostly for nanowires, reduced the nanoalloy size between 2.4 nm to 5 nm [25,26]. For example, stabilizing the pH level of the mixture around 9.5-10 with strong bases, such as NaOH or KOH, results in a decrease in the particle size below 7 nm [27,28]. On the other hand, sodium borohydride (NaBH 4) is a secondary reducing agent which was provided successful results for the polyol process of Cu, Ni, Co NPs in ethylene glycol (EG) by slow addition of NaBH4 produced fairly monodisperse isotropic NPs [23].…”
