| 英文摘要 | A new system for the production of hydrogen, constructed using silica gel as a matrix, eosin y as a photosensitizer, and pt as a cocatalyst, has been reported. it was found that the rate of photosensitized hydrogen evolution in the presence of silica gel is enhanced about 10-fold relative to the homogeneous phase, i.e. in the absence of silica gel. the ph value of the solution and the concentration of eosin y have remarkable effects on the rate of hydrogen evolution. the optimal ph and concentration of eosin y are 7 and 3.60 x 10(-4) mol dm(-3) (e/s = 1/3) to 7.24 x 10(-4) mol dm(-3) (e/s = 1/1), respectively. triethanolamine (teoa) as an electron donor, the rate of hydrogen evolution and the apparent quantum efficiency in the silica gel system under visible-light irradiation (lambda >= 420 nm) can reach about 43 mu mol h(-1) and 10.4%, respectively. in addition, the roles of silica gel, pt and teoa, respectively; and the probable mechanism of photosensitized hydrogen evolution have been discussed.
