Quantum efficiency of Pd/TiO2 catalyst for photocatalytic reforming of methanol in ultra violet region

The efficiency of Pd/TiO2 catalyst for photocatalytic reforming of methanol was investigated in ultra violet, UV region by monitoring the volume of H-2 production and the number of incident photon using chemical actinometry method. 2-nitrobenzaldehyde solution was used to evaluate the number of incident photon from solar light by monitoring the rate of photochemical isomerisation to 2-nitrobenzoic acid. The activity of Pd/TiO2 catalyst varies across UV region with the ability to utilise the incident photon for H-2 gas production is higher in UV-B. The quantum efficiency of the reaction was affected by the amount of catalysts concentration and the number of incident photons. [GRAPHICS] .
