“…In contrast, the linear feature band shifts down to 2,040 cm -1 for I-Pd/M-SiO 2 catalyst (Fig. 6c), which are red-shifted by about 50 cm -1 with respect to Pd/C-SiO 2 catalyst, and 30-40 cm -1 with respect to reference data for the similar Pd particle size (1-2 nm) [46]. Therefore, the red-shift derived from effect of the size-dependence can be rule out.…”

A novel Pd-based catalyst, small Pd nanoparticles (1-2 nm) fabricated on N,O-containing organic groups modified silica, exhibits unusual catalytic performance for selective hydrogenation of acetylene, that is, the ethylene selectivity rises significantly with the increase of acetylene conversion regardless of the variation of reaction temperature or hydrogen partial pressure until 100% acetylene conversion. The in situ DRIFTS spectra of CO adsorption show that the organic groups presented on the silica affect the electronic property of the very small Pd nanoparticles.

“…4, the fresh Pd sample without Al 2 O 3 over-coats exhibited two main peaks at 2095 and 1978 cm -1 and a pronounced broad shoulder near 1933 cm -1 . These three peaks can be assigned to linear CO on the Pd corner atoms, l 2 bridge-bonded CO on the step and edge sites of Pd NPs, and l 2 bridge-bonded CO on Pd (111) facets, respectively [17,18]. In the methanol decomposition reaction two competing pathways exist.…”

“…Infrared (IR) spectroscopy of CO chemisorption on Pd NPs has been used extensively and the relationships between the IR features and the properties of Pd NPs are well understood [17][18][19][20][21]. Consequently, we employed diffuse reflectance IR spectroscopy (DRIFTS) to study CO chemisorption on the Pd samples with and without the Al 2 O 3 over-coats.…”

Alumina Over-coating on Pd Nanoparticle Catalysts by Atomic Layer Deposition: Enhanced Stability and Reactivity

ALD Alumina was utilized as a protective layer to inhibit the sintering of supported nano-sized ALD Pd catalysts in the methanol decomposition reaction carried out at elevated temperatures. The protective ALD alumina layers were synthesized on Pd nanoparticles (1-2 nm) supported on high surface area alumina substrates. Up to a certain over-coat thickness, the alumina protective layers preserved or even slightly enhanced the catalytic activity and prevented sintering of the Pd nanoparticles up to 500°C.

However, a survey of the literature indicates a paucity of work examining the interaction of oxygenates and esters in particular on oxide surfaces. Preliminary studies on silicas similar to that used with the Alpha process are believed to indicate the presence of both weak Brønsted acid and Brønsted base sites, 2 although the evidence for these assertions is not in the public domain.This paper is divided into two parts. To our knowledge, methyl propanoate has been neither structurally nor spectroscopically characterised; thus, Part 1 provides a comprehensive description of the solid state structure and vibrational spectroscopy of methyl propanoate in the gas, liquid and solid phases, with assignments supported by periodic density functional theory (DFT). In Part 2 we characterise the adsorption of methyl propanoate on a representative silica (Fuji Q-10 silica spheres). Previous work by Jackson and coworkers examined the adsorption of acetic acid on this particular silica, as well as Cs-doped Q-10, with the latter constituting model methyl methacrylate synthesis catalysts. 6 That work followed on from a patent filed in 1999 by Jackson and co-workers at ICI (UK) entitled 'novel catalyst for manufacture of ethylenically unsaturated acids or esters, especially for manufacture of methyl methacrylate'. 7 Silica spheres, as opposed to silica powder, are attractive to industrial use as bulk handling properties are simplified. Against this background, Fuji Q-10 silica is examined in this communication. The combined structural and spectroscopic
