A facilely synthesized highly active Pd nanoparticle electrocatalyst for electroless deposition process

Abstract

Pd nanoparticles chemically synthesized by respective reducing agents were evaluated in the hypophosphite oxidation reaction for initiating electroless Ni deposition.

One Pot Bio-Synthesis of Palladium Nanoneedles and Its Bioavailability

“…As well as palladium is well known for its catalytic activity as oxidative convertor of glycerol [23], as automotive catalyst [24], oil re ning process [25], polyester manufacturing [26] and bacterial reduction of graphene oxide (GO) and Pd (II) salt supported E. coli utilized for production of H 2 and sodium formate [27]. Chemical synthesis of palladium nanoparticles was used chemicals such as NH 4 OH [28], NaBH 4 [29,30], SnCl 2 [31] and bio-materials like cupriavidus necator and cupriavidus metallidurans [32], gardenia jasminoides [33], bark extract of cinnamom zeylanicum [34], plectonema boryanum [2], desulfovibrio desulfuricans [35], shewanella oneidensis [36], escherichiacoli [37], desulfovibrio fructosivorans [38], clostridium pasteurianum [39], coffee [40] and tea [40] extract as a cost-effective method. Among that chemical synthesis method is complicated, using harsh conditions and chemicals will show side-effect on human health.…”

Prussian Blue‐Derived Iron Phosphide Nanoparticles in a Porous Graphene Aerogel as Efficient Electrocatalyst for Hydrogen Evolution Reaction

“…[11] Therefore, it is vital to developafacile synthetic methods for metal phos-phide based catalytic systems. [12][13][14][15][16] Recently,m any HER active metal phosphide catalysts were accomplished through thermal decomposition of hypophosphite. [17,18] The later method comprises maximum three and minimum two steps to accomplish the final product.…”

“…Among these, transition metal phosphides of Co, Fe, and Ni have received greater attention, because of its very low HER overpotential . Therefore, it is vital to develop a facile synthetic methods for metal phosphide based catalytic systems . Recently, many HER active metal phosphide catalysts were accomplished through thermal decomposition of hypophosphite .…”

Development of electroless plating processes for low cost plastic-metallization and area-selective metal coating of three-dimensional structures

“…[30] Desmond C.L. Tan et al posted a stepwise method of synthesizing Pd-P amorphous catalyst with sodium hypophosphite (NaH2PO2), which displayed superior mass activity compared to Pd/Sn and Pd-N2H4, as illustrated inFigure 4below [31,32].…”
