2. The photo-current detection experiment with photo-anode (three electrode (work electrode, cathode electrode and reference electrode) in KOH/H2O electrolyte), a photo-voltage meter and current meter was pplied to monitor the current and coltage between work and cathode electrode), the photon source could be laser or focused LED light. The photo-anode material could be ?
