Hydrogen Peroxide Synthesis via Enhanced Two-Electron Oxygen Reduction Pathway on Carbon-Coated Pt Surface
TL;DR: In this paper, a controlled coating of Pt catalysts with amorphous carbon layers can induce selective end-on adsorption of O2 on the Pt surface by eliminating accessible Pt ensemble sites, which allows significantly enhanced H2O2 production selectivity.

Hydrogen Spillover in Encapsulated Metal Catalysts: New Opportunities for Designing Advanced Hydroprocessing Catalysts
TL;DR: In this article, the authors provide an overview of the recent progress made with encapsulated metal catalysts, which can act as an ideal model catalyst for proving the existence and catalytic functions of hydrogen spillover.

Cross-Linked “Poisonous” Polymer: Thermochemically Stable Catalyst Support for Tuning Chemoselectivity
TL;DR: In this article, the entire surfaces of the Pd clusters were ligated (or poisoned) by sulfide groups of the polymer support, which enabled exceptionally discriminative adsorption of alkynes over alkenes.

Significant Roles of Carbon Pore and Surface Structure in AuPd/C Catalyst for Achieving High Chemoselectivity in Direct Hydrogen Peroxide Synthesis
TL;DR: In this article, the role of surface properties and porous structures of the carbon supports was investigated for small-scale/on-site H2O2 production, and the results showed that a high density of oxygen functional groups on the carbon surface was essential for synthesizing highly dispersed bimetallic catalysts with effective AuPd alloying, which is a prerequisite for achieving high H 2O2 selectivity.

Comprehensive Understanding of the Effects of Carbon Nanostructures on Redox Catalytic Properties and Stability in Oxidative Dehydrogenation
TL;DR: In this article, the properties of 16 different types of carbons, including activated carbon, carbon nanotubes, onion-like carbons and microporous/mesoporous templated carbons were systematically investigated using n-butane oxidative dehydrogenation as a model reaction.
