“…These encompass organic compounds (e. g., aldehydes, carbohydrates), salts of inorganic acids (e. g., hypophosphite, sulfite), boron-hydrogen compounds, and compounds with weak nitrogen/oxygen single bonds and a strong tendency to decay into N 2 or O 2 (e. g., hydrazine, hydroxylamine, hydrogen peroxide). Occasionally, reducing metal ions [42,79,83] and sulfur compounds [48] are used as well.…”

Electroless plating is commonly associated with metallizing macroscopic work pieces, but also represents a surprisingly powerful nanomanufacturing tool. This review details the technique's use for creating nanomaterials of arbitrary dimensionality, ranging from nanoparticles over nanotubes, nanowires, and ultrathin films to nanostructured lattices, focusing on the solution chemistry and mechanistic aspects. The synthesis of defined nanostructures serves as overarching perspective, which is enriched by drawing connections to and insights from related fields. Strategies for controlling the size, shape, crystallinity, porosity, composition, and arrangement of electrolessly plated nanostructures are outlined, including templating (which harnesses the method's exceptional conformality to guide and limit deposit formation), the complementary approach of selective growth, tailored seeding, and bath design. Being able to strike convincing compromises between material quality and ease of preparation, electroless nanoplating has a distinct potential to facilitate the application of metal nanomaterials.

“…It is worth noting that Co 2+ complexes with different amines have found application as reducing agents for electroless deposition of metals different from Cu. The authors successfully used the Co 3+ -Co 2+ -ammonia redox couple for the deposition of silver coatings [34,35]. Electroless gold plating was carried out when using trimethylene diamine as a Co 2+ ligand [29].…”

In the present work, the kinetics of electroless deposition of Pt, using a cobalt ion redox system (Co3+/Co2+) as a reducing agent, has been investigated. The deposition rate of Pt depends on the pH, concentration of reactants, and temperature. The deaeration and bubbling of the plating solution with argon play an essential role. It was found that 0.11 mg cm−2 of Pt films could be deposited on the surface of a roughed glass sheet in one hour without replenishing the solution. Additional data have been obtained on the grounds of electrochemical quartz crystal microbalance experiments. The bubbling (agitation) of the electroless Pt plating solution with argon during the deposition of Pt results in a higher deposition rate and is ca. 3 µg cm−2 min−1. The Pt deposition rate is far less, and is as low as 0.14 µg cm−2 min−1 when the electroless Pt plating solution is not bubbled with argon during the deposition of Pt.

“…These include spectrophotometric, 9,10 flow injection, 11 atomic absorption, 12 and polarographic. 13 A number of catalytic kinetic methods, for analysis of Co(II) have been reported. 14,15 These methods often possess low sensitivity and require separation and preconcentration.…”

A novel kinetic method for the determination of trace amounts of Co(II) has been developed. The proposed method based on the catalytic effect of Co(II) on the oxidation of xylenol orange tetra sodium salt by H2O2 in the presence of cationic surfactant (N-dodecylpyridinium chloride). Co(II) at mg.mL -1 was determined spectrophotometrically by measuring the decrease in the absorbance of xylenol orange at 577 nm by the differential method. The method is precise, selective, and sensitive. The detection limit of the procedure was 0.058 mg.mL -1 . The relative standard deviation for the replicate determination (n = 6) of 0.7 mg.mL -1 was 1.285%. The results compared satisfactorily with those of atomic absorption spectrometry. The method was successful for the analysis of Co(II) in veterinary and synthetic samples.
