A Ni-foam structured MoNi4–MoOx nanocomposite catalyst is highly active, selective and stable for the gas-phase hydrogenation of dimethyl oxalate to ethanol.
NiCu MOF nanosheets on Ni foam (NiCu-MOFNs/NF) exhibit superior catalytic OER performance, needing an overpotential of 309 mV at 100 mA cm−2 in 1.0 M KOH.
Inspired by the advanced branch-leaf hierarchical structure of natural trees, a composite catalyst with branch-leaf-like hierarchical structure was reported for the first time. This catalyst, which grows on Ni foam,...
AbstractThe dissociation of N2 in a microwave discharge has been studied using a gas phase titration between N(4S) and NO. SF6 added in small concentrations (20–100 ppm of N2) is shown to be an efficient catalyst for dissociating N2. Dissociation fractions [N]/[N2 ] of 4–5% have been obtained. The studies suggest how the partial pressure of atomic nitrogen can be maximized. These results have been applied to thermal nitridation of Si in active nitrogen. A strong dependence of the film thickness on the partial pressure of atomic nitrogen (PN) has been shown. In addition to the nitridation rate, the nitrogen fraction [N]/([N] + [O]) also increases with PN.
