1. 介绍

Chemours Nafion PFSA聚合物分散体是由化学稳定的全氟磺酸(PFSA)/聚四氟乙烯(PTFE)酸(H+)形式制成的,有多种聚合物含量和分散剂组成。典型的用途包括用于燃料电池膜,催化剂涂层,传感器和各种电化学应用的薄膜和涂层配方的制造。

燃料电池应用: Nafion D520分散液(一种稀释的液体形式,用于PEM燃料电池膜的化学物质)通过将较大比例的铂暴露于氢气中而大大减少了催化剂所需的铂量。同样,Nafion充当粘合剂将铂,膜和气体扩散层固定在一起。

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.

3. Blocking polysulfides with a Janus Fe3C/N-CNF@RGO electrode via physiochemical confinement and catalytic conversion for high-performance lithium–sulfur batteries

Graphene oxide (GO) in this paper was obtained from SCI Materials Hub. The authors introduced a Janus Fe3C/N-CNF@RGO electrode consisting of 1D Fe3C decorated N-doped carbon nanofibers (Fe3C/N-CNFs) side and 2D reduced graphene oxide (RGO) side as the free-standing carrier of Li2S6 catholyte to improve the overall electrochemical performance of Li-S batteries.


4. A high-voltage and stable zinc-air battery enabled by dual-hydrophobic-induced proton shuttle shielding

This paper used more than 10 kinds of materials from SCI Materials Hub and the authors gave detailed properity comparsion.

The commercial IEMs of Fumasep FAB-PK-130 and Nafion N117 were obtained from SCI Materials Hub.

Gas diffusion layers of GDL340 (CeTech) and SGL39BC (Sigracet) and Nafion dispersion (Nafion D520) were obtained from SCI Materials Hub.

Zn foil (100 mm thickness) and Zn powder were obtained from the SCI Materials Hub.

Commercial 20% Pt/C, 40% Pt/C and IrO2 catalysts were also obtained from SCI Materials Hub.
