The single halide as well as the majority of the mixed halide nanocrystals do not show luminescence intermittency.

Hydrodeoxygenation (HDO) of three model compounds (i.e., anisole, 4-propylphenol, and 2-butanone) and real lignin pyrolysis vapors was investigated at 673 K and ∼1.7 bar of H 2 over a series of MoO 3 /γ-Al 2 O 3 catalysts with MoO 3 loadings ranging from 0 to 19 wt % as well as bulk MoO 3 . Extensive characterization revealed catalyst acidity (strength) and the degree of MoO x oligomerization as the two main parameters in determining product distribution. Strong Lewis acid sites of γ-Al 2 O 3 were found to catalyze transalkylation, dealkylation, dehydration, and condensation reactions, the latter of which also led to high coke yields (up to 50 C%). The addition of MoO 3 progressively reduced the amount of strong Lewis acid sites and generated weaker Lewis and Brønsted acid sites with lower selectivity to condensation reactions resulting in lower coke yields. The growth of MoO x domains depended on MoO 3 loading over the γ-Al 2 O 3 support. At MoO 3 loadings higher than 8 wt %, crystalline orthorhombic MoO 3 phases were found, which behaved similar to bulk MoO 3 in catalyzing hydrogenation and HDO reactions. The integration of MoO x species and acidity from the γ-Al 2 O 3 support enabled the modulation of product selectivity. This work provides information for enabling the rational design of supported MoO 3 catalysts to allow for maximizing the production of valuable chemicals (i.e., alkenes and aromatics) from HDO of lignin (or biomass) pyrolysis vapors.
