Density functional theory (DFT) calculations are performed to study the oxygen evolution reaction (OER) on tungsten oxide (WO3) surfaces. The free energies of the proton coupled electron transfer (PCET) steps are calculated and from these the OER ove

In this paper, bimetallic Pt-Ni/CeO2 catalysts supported over mesoporous silica were employed for ethanol reforming in the low-temperature range. In particular, catalyst behaviour was investigated under a H2O/C2H5OH/N2 as well as H2O/C2H5OH/AIR mixtu

A photocatalytic reaction mechanism that involves multielectron reduction of molecular oxygen (O 2 ), as a key step, in photocatalytic decomposition of acetic acid by pristine bismuth tungstate (Bi 2 WO 6 ; BWO) particles is proposed on the basis of

The mechanism of the formation of flake ball-shaped (FB) bismuth-tungstate (BWO) particles was studied with samples prepared by hydrothermal reactions under standard conditions (tungsten/bismuth ratio of 0.55 in feed; 433 K; 20 h) and other modified

The present density functional theory study provides insight into the effect of Fe promotion on the CO dissociation reaction on a stepped Rh surface. On the basis of a density of states analysis we demonstrate that Fe is able to promote the CO dissoc

Oxygenated compounds have previously been detected on spent Co/Al2O3FTS catalyst and have also been proposed to be precursors for carbon formation. Build-up of polymeric carbon on the catalyst during Fischer-Tropsch synthesis (FTS) can negatively inf

For reduction of particulate matter (PM) including soot in diesel exhaust gas, a diesel particulate filter (DPF) has been developed. However, it would be plugged with PM to cause an increase of filter backpressure. If the backpressure is too high, th
