Solid-solution alloying of immiscible Pt and Au boosts catalytic performance for H2O2 direct synthesis

Hong Woo Lee et al.

Summary: The study proposes solid-solution alloy nanoparticles composed of Pt and Au as an efficient catalyst for direct H2O2 synthesis on TiO2 support. The introduction of inactive Au atoms suppresses key reactions, leading to high selectivity. This research paves the way for utilizing immiscible elemental combinations in developing catalysts for direct H2O2 synthesis.

On the Reaction Mechanism of Direct H2O2 Formation over Pd Catalysts

Lin Chen et al.

Summary: Hydrogen peroxide (H2O2) is an effective green oxidant used in various industrial processes. This study focused on the reaction mechanism for direct formation of H2O2 from H2 and O2 over Pd catalysts, finding that Pd is in a hydride phase under typical reaction conditions. The importance of surface steps and high hydrogen coverage for enhancing the selectivity of the reaction towards H2O2 was demonstrated in the results.

Advanced Development Strategy of Nano Catalyst and DFT Calculations for Direct Synthesis of Hydrogen Peroxide

Geun-Ho Han et al.

Summary: Hydrogen peroxide is a simple oxidizing agent with growing use due to its environmental friendliness. The traditional method of manufacturing H2O2 through anthraquinone autoxidation (AO process) releases large amounts of organic solvents and requires significant energy. Direct synthesis of hydrogen peroxide (DSHP) offers a more sustainable solution, but faces challenges such as mass-transfer limitations and side reactions, requiring advanced technologies for catalyst development.

Shape Changes in AuPd Alloy Nanoparticles Controlled by Anisotropic Surface Stress Relaxation

Diana Nelli et al.

Summary: The shape of AuPd nanoparticles is engineered by surface stress relaxation through adjusting the Au content in Pd-rich compositions. Through computer simulations, it is confirmed that increasing Au content leads to a transition from FCC truncated octahedra to icosahedral structures due to better relaxation of anisotropic surface stress.
