PERSPECTIVES FOR APPLICATION OF HETEROGENEOUS PHOTOCATALYSIS IN LIQUID-SOLID SYSTEMS1
F The difficulty to make a clear assessment of the costs or the expensiveness of the photocatalytic processes have prevented a wider development of them by an application point of view.
F The chemical industry is characterised by the almost exclusive use of continuous processes. This type of operation calls for continuous (flow) reactors.
F The need to fulfil the requirement of continuous operation determines that the photocatalyst powder for potential application purposes should present suitable size and mechanical and fluidodynamic characteristics in addition to good catalytic properties.
