Platinum(II) hexafluoroacetylacetonate [Pt(hfac)2] was employed as the platinum precursor with formalin as the co-reactant for atomic layer deposition (ALD) of platinum nanoparticles on titanium oxide (TiO2) and tungsten oxide (WOx) substrates at 200°C. This study examined the surface chemistry and nanoparticle growth characteristics.
Key Findings:
· Surface Chemistry & Nanoparticle Formation: In situ FTIR spectroscopy confirmed Pt nanoparticle formation on TiO2 through a characteristic CO stretch peak at ~2100 cm-1 after alternating Pt(hfac)2 and formalin exposures. The FTIR spectra revealed Pt(hfac)2 adsorbs associatively on TiO2, mirroring the adsorption behavior of hexafluoroacetylacetone (hfacH). Adsorbed hfacH blocked subsequent Pt(hfac)2 adsorption, enabling nanoparticle density control. Preadsorption of hfacH reduced Pt coverage from 6-7 to 1-3 nanoparticles/100 nm2 and decreased average diameter from 2-3 nm to 1.5 nm.
· Nanoparticle Control Across Substrates: Pt nanoparticles grown on WOx showed similar characteristics to those on TiO2. TEM confirmed nanoparticle size increased with ALD cycle count. However, Pt(hfac)2/formalin required significantly more cycles than other ALD chemistries to achieve comparable particle sizes due to site-blocking by persistent hfac ligands.

Platinum(II) hexafluoroacetylacetonate [Pt(hfac)2] serves as a precursor for synthesizing monodisperse platinum nanoparticles in organic media. This case study examined its application in producing size-tunable nanoparticles through thermal reduction, leveraging β-diketonate reactivity in controlled environments.
· Synthesis Process: Pt(hfac)2 was reduced under nitrogen atmosphere in organic solvents (n-hexane, toluene, o-xylene, DMF) using tetraalkylammonium surfactants as stabilizers. In a representative procedure (Sample A3), Pt(hfac)2 (50.0 mg, 0.082 mmol) and CTAB (30.0 mg, 0.082 mmol) were dissolved in o-xylene (20 mL). The mixture was refluxed under nitrogen for 3 hours. Solution color transition from pale yellow to dark brown indicated nanoparticle formation. Particles were isolated via high-speed centrifugation and redispersed in organic solvents.
· Size Control Methodology: Particle size was modulated by three parameters, including surfactant chain length (tested stabilizers wrere DTAB, MTAB, CTAB, and OTAB), concentration ratios(varied Pt(hfac)2-to-surfactant molar concentrations), and reaction temperature.
· Key Results: Monodisperse, spherical, and well-dispersed Pt nanoparticles were obtained for all cases. The average size was in the range of 9-15 nm for all variations. The nanoparticles were redispersible in n-hexane, toluene, and o-xylene.
