TL;DR: The available technologies for the abatement of phenol from water and gaseous streams are briefly reviewed, and the recent advancements summarized.
1,175 citations
TL;DR: In this article, the chemical and mechanistic aspects of the selective catalytic reduction (SCR) of NO by ammonia and by methane have been investigated, and the classical NH 3 -SCR process, operating near 600k over vanadia-titania-based catalysts, is shown to imply the activation of NO x in the form of an adsorbed oxidized species, that reacts with the reductant, CH 4, from the gas phase or activation into the zeolite channels.

TL;DR: In this article, the constitutional data of the R-Cu-Al systems with R = rare earth are summarized and discussed, and the phase equilibria observed in the reported ternary systems are reviewed with special attention given to the isothermal and polythermal sections of the phase diagrams.
Abstract: Constitutional data of the R-Cu-Al systems, with R = rare earth, are summarized and discussed. Crystal structures of the phases formed in the binary boundary systems and in the ternary systems are assessed, and the phase equilibria observed in the reported ternary systems are reviewed with special attention given to the isothermal and polythermal sections of the phase diagrams. Some regularities observed in the trends of the constitutional properties of the ternary R-Cu-Al alloys are briefly described.

TL;DR: In the current and medium-term the production options for hydrogen are first based on distributed hydrogen production from electrolysis of water and reforming of natural gas and coal as discussed by the authors, and each of centralized hydrogen production methods scenarios could produce 40 million tons per year of hydrogen.
1,036 citations
TL;DR: In this article, a review examines the recent literature on the oxidative dehydrogenation (ODH) of ethane and propane, which aims for the synthesis of the corresponding alkenes.

TL;DR: In this article, the effects of various operating parameters on the photocatalytic degradation of phenols and substituted phenols are presented, such as type of photocatalyst and composition, light intensity, initial substrate concentration, amount of catalyst, pH of the reaction medium, ionic components in water, solvent types, oxidising agents/electron acceptors, mode of catalyst application, and calcination temperatures.

TL;DR: A considerable part of the available literature on scandium in aluminium alloys is reviewed in this article, with emphasis on the aluminium rich part of diagrams, including a wide range of ternary Al-Sc-X phase diagrams and a few higher order phase diagrams.
Abstract: A considerable part of the available literature on scandium in aluminium alloys is reviewed. Experimental data and assessments of the binary Al–Sc phase diagram, a wide range of ternary Al–Sc–X phase diagrams and a few higher order phase diagrams are accounted for, with emphasis on the aluminium rich part of the diagrams. The phase which is in equilibrium with Al, Al3Sc, can form by several different mechanisms, all of which are described. The precipitation kinetics of Al3Sc in binary Al–Sc alloys are discussed, and an overview of the reported influences of ternary alloying elements on the precipitation of Al3Sc is given. The Al3Sc phase particles can serve as a grain refiner in the Al melt, a dispersoid for controlling the grain structure of the alloy and a strengthening precipitate. Several examples of these three effects are mentioned, both in binary Al–Sc alloys, and in more complex alloys. The reported effects of Sc on the precipitation behaviour in Al–Cu, Al–Mg–Si, Al–Zn–Mg and Al–Li alloys ...
