Importance of Pore Size and Lewis Acidity of Pt/Al2O3 for Mitigating Mass Transfer Limitation and Catalyst Fouling in Triglyceride Deoxygenation
TL;DR: In this paper , the catalytic effects of porous structure and surface acidity of Pt/Al2O3 were rigorously investigated in triglyceride deoxygenation, and the results showed that large mesopores were essential to obtain maximum catalytic activity without mass transfer limitation and to suppress catalyst deactivation by fouling.

Microfluidic synthesis of atto-liter scale double emulsions toward ultrafine hollow silica spheres with hierarchical pore networks.
TL;DR: Three-dimensional flow-focusing geometry is advantageous for stably producing femto- to atto-liter droplets without the retraction problem of the dispersed phase fluid and it is demonstrated that the double emulsions can be used as morphological templates of ultrafine spherical silica capsules with controlled hierarchical pore networks via the evaporation-induced self-assembly (EISA) method.

Selective Dissociation of Dihydrogen over Dioxygen on a Hindered Platinum Surface for the Direct Synthesis of Hydrogen Peroxide
TL;DR: In this article, the selective dissociation of H2 over O2 was realized by the deposition of H 2-selective carbon diffusion layers on a Pt catalyst, where O2 hydrogenation occurs at the carbon surface from spilt-over hydrogen rather than at the Pt surface where OO dissociation is likely.

Sodium-free synthesis of mesoporous zeolite to support Pt-Y alloy nanoparticles exhibiting high catalytic performance in propane dehydrogenation
TL;DR: In this paper, a mesoporous MFI zeolite with silanol nests was synthesized using diammonium-type bromide surfactants and a sodium-free silica source.

Single-step hydroconversion of triglycerides into biojet fuel using CO-tolerant PtRe catalyst supported on USY
TL;DR: In this article, a CO-tolerant bimetallic PtRe on ultra-stable Y (USY) zeolite as acidic support was synthesized for direct triglyceride hydroconversion.
