Example Embodiment
[0065] Example 1
[0066] The preparation method of photocatalytic hydrogen production catalyst in this example is as follows:
[0067] (1) TIO 2 preparation:
[0068] 0.45 g of polyvinylpyrrolidone (PVP), 3 ml of glacial acetic acid and 1.5 g of titanate tetrabutyate were dissolved in 3 ml of methanol to form a mixed liquid, and the mixture was stirred at room temperature (25 ° C) for 12 hours to obtain a clear solution; transfer solution transfer In the injection device, the electrospun wire is then performed, the voltage of the electrospinning is 18 kV, the feed speed is 0.5 ml / h, the height of the electrospun wilflow distance collector is 14cm; the nanofibers formed after the electrospinning Transfer to the crucible and sintering in the muffle furnace to go to the excess polyvinylpyrrolidone and other organic components. The Master furnace sintering temperature was 550 ° C, the time was 2 hours, the mass furnace rose rate was 1 ° C / min; after 2 hours, the crucible was quic...
