Overview

Horizontally mounted, double compartment Photo-Electrochemical Flow H-Cell for simultaneous investigation of thin film photo-anode and photo-cathode. All cell elements are made of PEEK. Suitable for aqueous (EPDM/FKM O-Rings) and organic solvent (FFKM O-Rings) electrolytes. Liquid-tight construction with two separate chambers, each equipped with electrolyte inlet and outlet, allowing solution flow and evacuation of reaction products. 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. Reservoirs may be equipped with electrodes (e.g. pH meter probes) and exhaust gases may be supplied to gas analysis (e.g. Gas Chromatography). Gas purging (via mass flow controller) and ice cooling may also be applied.

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