Continuous Preparation of Carbon-Nanotube-Supported Platinum Catalysts in a Flow Reactor Directly Heated by Electric Current

The synthesized catalysts show a high degree of dispersion and narrow distributions of cluster sizes. In comparison to catalysts synthesized by the conventional oil-bath method a significantly higher electrocatalytic activity was reached, which can be attributed to the higher metal loading and smaller and more uniformly distributed Pt particles on the carbon support. Our approach introduces a simple, time-saving and cost-efficient method for fuel cell catalyst preparation in a flow reactor which could be used at a large scale.

Catalysis is common in many industries such as pharmaceutical, specialty chemicals, agriculture, polymer and over 90% of chemicals are made from catalytic processes. Researchers have reported an asymmetric reaction that uses a cationic (positively charged) catalyst to convert racemic (equal mixture of two enantiomers) substrates to asymmetric product via an intriguing reaction route,READ MORE
