Synthesis and Characterization of Cobalt/Manganese Bimetallic Nanocatalyst Prepared via Reverse Microemulsion Method [PDF]

, 2013
The bimetallic cobalt-manganese nanocatalyst was synthesized via reverse microemulsion method. The reverse microemulsion was used as an alternative route to prepare the nanocatalyst rather than common catalyst preparation route, impregnation method as

Acceptor‐Doped Cerium Oxides Enabling Metallic Nanocatalyst Exsolution for Hydrogen Production From Ammonia

Angewandte Chemie, EarlyView.
Outstanding catalytic results for NH3 decomposition for H2 production were obtained with metallic Ru, Rh, and RuRh nanoparticle‐exsolved CeO2‐based catalysts. Significant lower amounts of available superficial metallic fractions were needed in comparison to conventional Ru‐impregnated materials.

Overcoming the Catalytic Bucket Effect in Pt‐based High‐Entropy Nanocages Through Interface Defect and Strain Engineering

Advanced Science, EarlyView.
PtPdNiCuMnAu HENCs exhibit a remarkable half‐wave potential (E1/2) of 0.925 V vs. RHE. The catalyst displays exceptional electrochemical stability, with only a 4 mV negative shift in E1/2 and a mere 5.6% loss in MA after 10, 000 accelerated durability test cycles.

Continuous‐Flow Microfluidic Synthesis Enhances C2+ Selectivity for Cu2O Catalysts

Advanced Science, EarlyView.
Microfluidic devices are used to prepare Cu2O nanoparticles under laminar flow conditions, which exhibit enhanced selectivity in the CO2‐to‐C2+ reaction due to their nanoporosity and high defect concentration. Cu2O prepared using standard solution methods displays decreased CO2‐to‐C2+ selectivity due to the absence of similar properties. Altogether, we

A supramolecular peptide nanofiber templated Pd nanocatalyst for efficient Suzuki coupling reactions under aqueous conditions [PDF]

, 2012
A bioinspired peptide amphiphile nanofiber template for formation of one-dimensional Pd nanostructures is demonstrated. The Pd and peptide nanocatalyst system enabled efficient catalytic activity in Suzuki coupling reactions in water at room temperature.
