TL;DR: The higher activity of the monoclinic ZrO2 sample for the photocatalytic degradation of methyl orange can be attributed to the combining effects of factors including the presence of small amount of oxygen-deficient zirconium oxide phase, high crystallinity, large pores, and high density of surface hydroxyl groups.

TL;DR: Spectroscopic evidence is provided for the formation of surface acetate and methyl acetate, as well as dimethoxymethane during the MTO process, suggesting a direct mechanism may be operative, at least in the early stages of theMTO reaction.

TL;DR: The operando spectroscopy results suggest that the nature of the active species also influences the olefin selectivity, and monoenylic and highly methylated benzene carbocations are more selective to the formation of propylene.

TL;DR: In this paper, the thermal conductivity of an ultralight nanocarbon aerogel is investigated with a view to potential applications as energy-efficient, local gas heater, and other systems.

TL;DR: In this article, a series of mixed metal oxides (MMOs) adsorbents (MgAl, CuAl- and CoAl-MMO) were supported on graphene oxide (GO) through in-situ precipitation of layered double hydroxides (LDHs) onto exfoliated GO, followed by thermal conversion.
