1. 介绍

Core/Shell Ir/IrOx catalyst powder (previously known as Iridium Oxide (IrO2), conductive catalyst) has a particle size of around 12 nm with a surface area of around 20 m2/g. This catalyst is synthesized in the form of core/shell configuration with the core being iridium metal and the shell being iridium oxide. Since the core is pure iridium metallic, the overall electrical conductivity of this catalyst product is higher compared to pure IrOx or pure IrO2 catalysts. Furthermore, use of the core/shell configuration helps to increase the electrochemical surface area for the iridium oxide compared to conventional methods of making the pure IrOx or IrO2.

This catalyst product can be used for standard PEM electrolyzers that use deionized water and not other additives (such as acids or bases or salts dissolved in the water). This core/shell catalyst can also be used for various other electrochemical applications (such as fuel cells, batteries, supercapacitors, electrolytic capacitors, etc.).

For non-standard applications such as acidic water, alkaline water, or salt containing water electrolysis applications, we advise the researchers and customers to check the chemical compatibility of IrOx and Ir metal for their application and ensure that this product would have sufficient corrosion stability in the intended application. If the intended application has electrolytes that would dissolve this core/shell Ir/IrOx catalyst in partial or full would result in performance degradation.

1. Strain Relaxation in Metal Alloy Catalysts Steers the Product Selectivity of Electrocatalytic CO2 Reduction

The bipolar membrane (Fumasep FBM) in this paper was purchased from SCI Materials Hub, which was used in rechargeable Zn-CO2 battery tests. The authors reported a strain relaxation strategy to determine lattice strains in bimetal MNi alloys (M = Pd, Ag, and Au) and realized an outstanding CO2-to-CO Faradaic efficiency of 96.6% with outstanding activity and durability toward a Zn-CO2 battery.


2. Boosting Electrochemical Carbon Dioxide Reduction on Atomically Dispersed Nickel Catalyst

In this paper, Vulcan XC-72R was purchased from SCI Materials Hub. Vulcan XC 72R carbon is the most common catalyst support used in the anode and cathode electrodes of Polymer Electrolyte Membrane Fuel Cells (PEMFC), Direct Methanol Fuel Cells (DMFC), Alkaline Fuel Cells (AFC), Microbial Fuel Cells (MFC), Phosphoric Acid Fuel Cells (PAFC), and many more!


3. Partially Nitrided Ni Nanoclusters Achieve Energy-Efficient Electrocatalytic CO2 Reduction to CO at Ultralow Overpotential

An AEM membrane (Sustainion X37-50 Grade RT, purchased from SCI Materials Hub) was activated in 1 M KOH for 24 h, washed with ultra-purity water prior to use.
