Abstract: There is described a photocatalyst composition of matter comprising a support material. A surface of the support material configured to comprise: (i) a first catalytic material for catalyzing the conversion of H2O to H2 and O2, and (ii) a second catalytic material catalyzing reaction of hydrogen with a target compound. The photocatalyst composition of matter can be used to treat an aqueous fluid containing a target chemical compound, for example, by a process comprising the steps of: (i) contacting the aqueous fluid with the above-mentioned photocatalyst composition of matter; (ii) contacting the aqueous fluid with radiation during Step (i); (iii) catalyzing the conversion of water in the aqueous fluid to H2 and O2 with the first catalytic material; and (iv) catalyzing reaction of the target chemical compound in the aqueous fluid with hydrogen from Step (iii) in the presence of the second catalytic material to produce a modified chemical compound.

Abstract: An optical radiation sensor device includes a radiation collector for receiving radiation from a predefined arc around the collector within the field and redirecting the received radiation along a predefined pathway; motive means to move the radiation collector from a first position in which a first portion of the predefined arc is received by the radiation collector and a second position in which a second portion of the predefined arc is received by the radiation collector; and a sensor element capable of detecting and responding to incident radiation along the pathway when the radiation collector is in the first position and in the second. The use of the optical radiation sensor device in a radiation source module and in a fluid treatment system is also described.

Abstract: There is disclosed an optical radiation sensor system. The system includes a sensor device (140) and a cleaning device (115). The sensor device detects a nd responds to radiation from a radiation field (170) and includes a surface (155) that is movable with respect to the radiation field between a first position in which the surface is in the radiation field and a second positio n in which at least a portion of the surface is out of the radiation field. Th e cleaning device operates to remove fouling materials from at least a portion of the surface in the second position. The cleaning device may be a chemical cleaning device, a mechanical cleaning device or a combined chemical/mechanical device.
