Overview

PTFE variant of the PECF H-Cell 2x1.5 mL. All elements in contact with electrolyte or its fumes are made of PTFE and other fluorinated materials (tubing, fittings, O-Rings). Used wherever PEEK fails, specifically with aggressive electrolytes including: aqua regia, bromine, carbolic acid (phenol), carbon disulfide, chlorosulfonic acid, chromic acid (>50%), hydrofluoric acid, nitric acid (>50%), sulphuric acid (96%), fuming sulphuric acid, and other strongly oxidising or halogenated media.

Horizontally mounted, double compartment Photo-Electrochemical Flow H-Cell for simultaneous investigation of thin film photo-anode and photo-cathode. Liquid-tight construction with two separate chambers, each equipped with an electrolyte inlet and outlet. Chambers are separated by an ion-exchange membrane (e.g. DuPont Nafion® membrane).

Application Note

Designed to investigate performance of a thin film photo-anode and/or photo-cathode (e.g. nanocrystalline material or conducting polymer) deposited on a rigid or flexible transparent substrate (typically fused quartz glass). The thin film photo-cathode (counter electrode) deposited on a rigid or flexible substrate is mounted in the second chamber. Alternatively, a metal wire counter electrode may serve as a cathode. One or two classical reference electrodes are mounted in flow chambers. The cell should be connected with two external electrolyte reservoirs to circulate the electrolytes using peristaltic pumps. Gas purging and ice cooling may also be applied.

Typical applications: basic photochemistry, photolytic water splitting, photoinduced charge separation, photocorrosion and CO2 reduction.
