• Plant tannin used as stabiliser for palladium nanoparticles in selective hydrogenation of quinoline

  There are pros and cons to both homogeneous and heterogeneous catalytic strategies but one way you could get the best of both worlds is to use aqueous-organic biphasic catalysis. This approach hasn’t been widely utilised so far due to interfacial resistance between the phases which restricts catalyt more

• Palladium-gold nanoparticles clean TCE a billion times faster than iron filings

  In the first side-by-side tests of a half-dozen palladium- and iron-based catalysts for cleaning up the carcinogen TCE, Rice University scientists have found that palladium destroys TCE far faster than iron -- up to a billion times faster in some cases. The results will appear in a new study in the more

• Cheap and Cheerful: Iron to Replace Palladium
  

  Precious metals are expensive and in demand, not just for jewellery or as a financial investment, but also in industry. Here, valuable metals are used, among other things, as catalysts in chemical reactions. For example, palladium is crucial in a decisive step in the production of polyethylene, the more

• The Determination of Hazardous Substances According to RoHS and WEEE Directives
  

  1st July 2006 is an important deadline for the electro- and electronics industries. This date bans hazardous substances like lead, cadmium, mercury, hexavalent chromium and polybrominated biphenyls and diphenyl ethers from electro- and electronic equipment. This restriction, even though in discussion since 1991, has become more and more important from year to year because of tons of electronic waste releasing toxic substances which are accumulated in the environment, the food chain and all human beings. In order to enforce the substances ban and the limitation or substitution of hazardous components, elemental analysis is obviously the most important control measure for monitoring limiting values. This requires precise analytical systems such as X-ray fluorescence, ICP- and atomic absorption spectrometers. These instruments are able to detect trace concentrations of hazardous compounds - for example cadmium, using an atomic absorption spectrometer in the flame atomization mode up to 0.1 mg/L, or using the di more

• Mizoroki–Heck reactions catalyzed by palladium dichloro-bis(aminophosphine) complexes under mild reaction conditions. The importance of ligand composition on the catalytic activity

  Dichloro-bis(aminophosphine) complexes of palladium with the general formula [(P{(NC5H10)3−n(C6H11)n})2Pd(Cl)2] (where n = 0–2) are easily accessible, cheap and air stable, highly active and universally applicable C–C cross-coupling catalysts, which exhibit an excellent functional group tolerance.

• Palladium-catalyzed conjugate addition of arylsulfonyl hydrazides with [small alpha],[small beta]-unsaturated ketones

  A palladium-catalyzed desulfitative-denitrogenative conjugate addition of arylsulfonyl hydrazides with α,β-unsaturated ketones is described. The reaction showed very good selectivity and tolerated a wide range of functionalities under an atmosphere of oxygen with or without the aid of metal co-oxida more

• Synthesis and electrocatalytic activity of highly porous hollow palladium nanoshells for oxygen reduction in alkaline solution

  A series of hollow Pd nanoshells are prepared by employing Co nanoparticles as sacrificial templates with different concentrations of Pd precursor (1, 6, 12, 20, and 40 mM K2PdCl4), denoted as hPd-X (X: concentration of K2PdCl4 in mM unit). The synthesized hPd series are tested as a cathodic electro more
