Two facilities have been built to perform the photocatalytic and photoelectrochemical reduction of CO₂. The photocatalysis reduction of CO₂ for gas or liquid phases is performed under UV (365 nm) and visible light source (optical fibre with tuneable light intensity, 50-150 mW cm^-2). The gas phase reactor is made of stainless steel with a quartz window on top of the reactor and is connected to a gas chromatograph (GC) for product analysis. The customised reactor allows the placement of samples in the form of powder, thin film or mesh. The humidity throughout the experiment is monitored with a humidity sensor. The reacting temperature can be varied between room temperature to 80 ºC, whereas the flow of CO₂ can be varied between 0.07-8 mL min^-1.

The liquid phase reactor, which can be pressurise up to 5 bar, has a similar feature as the gas phase. The products obtained can be analysed using GC or Nuclear Magnetic Resonance (NMR). The customised liquid phase reactor can also be used for other photocatalytic reaction in liquid phase, such as photocatalysis of propylene oxide to cyclic carbonates, and is fitted with a solar simulator.

Photoeletrochemical rig is used for photoelectrochemical reduction of CO₂ and other form of photoelectrochemical reactions and analysis. The electrochemical workstations (AutoLab PGSTAT 302N and Chi660E), which allow a voltage range of +/- 10 V and current range of +/- 250 mA connected can be used to for material fabrication (electrodeposition and anodization), electrochemical testing, such as chronoamperometry, cyclic voltammetry, electrochemical impedance spectroscopy (EIS). The customised membraneless photoelectrochemical reactor is available for photoelectrocatalytic reduction of CO₂ testing.
