The effects of three common titanate photocatalysts (TPC) on the photo fermentation biohydrogen production (PFHP) from corn stover were studied in this paper. Compared with CaTiO and BaTiO, the experimental group with the addition of MgTiO showed stronger potential for PFHP, the maximum hydrogen yield of 344 mL (68.8 mL/g TS) was obtained at 3 g/L MgTiO, increased by 48.3%. For CaTiO, BaTiO, the optimal amount of addition was 8 and 7 g/L, respectively, in which, the hydrogen yield was 308 and 288 mL (61.6 and 57.6 mL/g TS). TPC addition could shorten the delay period of hydrogen production lower the Oxidation-Reduction Potential (ORP) of fermentation broth, especially MgTiO addition, the delayed hydrogen production could be shortened by 33.2% compared with control group, and the ORP could reach the lowest value of -371 mV.
本文研究了三种常见的钛酸盐光催化剂（TPC）对玉米秸秆光发酵生物制氢（PFHP）的影响。与 CaTiO 和 BaTiO 相比，添加 MgTiO 的实验组显示出更强的 PFHP 潜力，在 3g/L MgTiO 下获得了 344mL（68.8mL/g TS）的最大氢气产量，增加了 48.3%。对于 CaTiO 和 BaTiO，最佳添加量分别为 8 和 7g/L，其中氢气产量分别为 308 和 288mL（61.6 和 57.6mL/g TS）。TPC 的添加可以缩短产氢的延迟期，降低发酵液的氧化还原电位（ORP），特别是添加 MgTiO 可以将延迟产氢缩短 33.2%，与对照组相比，ORP 可达到最低值-371mV。
