Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...
A temperature programmed treatment of MoO3 in flowing N-2 + H-2 has been employed to prepare beta-phase molybdenum nitride (beta-Mo2N) which has been used to promote, for the first time, the catalytic hydrogenation of p-chloronitrobenzene. The reduction/ni ...
A tetragonal molybdenum nitride (β-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N2 + H2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; PH2=11bar) of a series of para-substitut ...
Electrochemical oxidation of ammonia (NH3 and NH4+) on boron-doped diamond (BDD) electrode was studied using differential electrochemical mass-spectrometry (DEMS) and chronoamperometry. Electro-oxidation of ammonia induces inhibition of the oxygen evolutio ...
FeZSM-5 with a wide range of Fe content (0.015–2.1 wt%) were studied in the benzene hydroxylation to phenol with nitrous oxide (C6H6:N2O = 1:5) at low temperatures (
The efficiency of Co(II)-, Mn(II)-, and Ti(IV)-doped carbon aerogels for the transformation of ozone into center dot OH radicals was investigated. The carbon aerogels had a markedly acid surface character (pH(PZC)congruent to 3-4) with very high surface ox ...
Boron doped diamond films have been deposited by large area hot-filament CVD (HFCVD) on silicon, silicon carbide, and different industrial electrode materials, like niobium, tantalum, titanium, tungsten, zirconium, and graphite on areas up to 40 cm * 60 cm ...
The chemical stability of bacteriogenic “UO2” is one of the seminal issues governing its success as an in-situ waste form in remediated subsurface locations. Little detail is known about the structure and reactivity of this material, but based on compariso ...
In order to understand better the mechanism of action of a permanent modifier based on Ir deposited on graphite furnaces pretreated by carbide-forming elements (W and Zr) an XPS investigation was carried out on samples submitted to thermal treatment simula ...
Boron nitride films were deposited by r.f. capacitively-coupled plasma (13.56 MHz) using two different gas mixtures: Ar-B2H6-NH3 and Ar-B2H6-N-2. In order to study the gas-phase reactions of the plasma in situ Fourier transform infrared absorption spectros ...
