In order to strengthen photo-fermentative hydrogen production by different photocatalytic nanoparticles , hydrogen production by photo-fermentative bacteria with addition of TiO 2 , ZnO and SiC nanoparticles in batch culture were investigated in this study. The results indicated that three nanoparticles could improve hydrogen production performance of Rhodopseudomonas sp. nov. strain A7 under respective optimal conditions. The hydrogen yield of 2.81 mol-H 2 /mol-acetate was obtained when TiO 2 nanoparticles with a concentration of 300 mg/L and size of 25 nm. The concentration of ZnO nanoparticles was at 100 mg/L, hydrogen yield reached 2.64 mol-H 2 /mol-acetate. Compared with TiO 2 and ZnO nanoparticles, SiC nanoparticles exhibited greatest potential for enhancing photo-hydrogen production. By addition of nano-SiC with concentration of 200 mg/L which was prepared at temperature of 1500 °C, the maximum hydrogen volume, average hydrogen content and hydrogen yield of strain A7 were achieved at 2272 mL-H 2 /L-culture, 85.2% and 2.99 mol-H 2 /mol-acetate, respectively. And hydrogen production was 18.6% higher than that of alone strain A7 without the addition of nanoparticles. Therefore, the addition of SiC nanoparticles is a promising strategy to improve photo-fermentative hydrogen production from wastewater.

This study investigated the mediating effect of Triethanolamine on Fe@C- Rhodobacter sphaeroides hybrid photosynthetic system to achieve efficient biohydrogen production. The biocompatible Fe@C generates excited electrons upon exposure to light, releasing ferrum for nitrogenase synthesis, and regulating the pH of the fermentation environment. Triethanolamine was introduced to optimize the electron transfer chain, thereby improving system stability, prolonging electron lifespan, and facilitating ferrum corrosion. This, in turn, stimulated the lactic acid synthetic metabolic pathway of Rhodobacter sphaeroides , resulting in increased reducing power in the biohybrid system. The ternary coupling system was analyzed through the regulation of concentration, initial pH, and light intensity. The system achieved the highest total H 2 production of 5410.9 mL/L, 1.29 times higher than the control (2360.5 mL/L). This research provides a valuable strategy for constructing ferrum-carbon-based composite-cellular biohybrid systems for photo-fermentation H 2 production.

This study explored the interrelationship between nano-TiO 2 addition and photo-fermentative hydrogen production (PFHP) of corn straw. The maximum cumulative hydrogen volume (CHV) was up to 688.8 mL under the optimal photo-fermentative process conditions with nano-TiO 2 addition of 300 mg/L. Initial pH and interaction between substrate concentration and light intensity had highly significant effects on PFHP of corn straw with nano-TiO 2 addition. With the improvement of CHV, nano-TiO 2 addition decreased the optimal initial pH and substrate concentration for PFHP of corn straw. Moreover, nano-TiO 2 addition promoted the metabolism of butyric acid and acetic acid by photosynthetic bacteria HAU-M1, and significantly reduced the total concentration of intermediate byproducts during hydrogen production to a low level of 1.6–2.5 g/L, thus making the CHV, maximum hydrogen production rate (HPR) and average hydrogen content (HC) increased by 32.6%, 27.9% and 8.3% respectively over the control without nano-TiO 2 addition.

The aim of this study was to analyze the effects of CaTiO 3 photocatalysts doped with different concentrations of Fe on the biohydrogen production process by photo-fermentation using corn stover as the substrate. The experimental results showed that the maximum cumulative hydrogen production and the maximum rate of hydrogen production were obtained when the doping concentration was 6 % (g/g) (380.8 mL, 26.4 mL/h), which were 63.4 % and 203.4 % higher, respectively, than those of the blank control group (233 mL, 8.7 mL/h). The substrate conversion rate was 32.82 %. Iron-doped CaTiO 3 lowered the oxygen reduction potential in the fermentation system to provide a suitable reduction environment for the growth and fermentation of photosynthetic bacteria . The lowest redox potential observed was −393.5 mV for 6 % iron-doped CaTiO 3 . Thermogram analysis revealed a strong correlation between cumulative hydrogen production and redox potential. Additionally, the analysis of soluble small molecules showed that iron-doped CaTiO 3 could inhibit the production of ethanol from glycolysis during fermentation and promote the utilization of small molecule acids.

Nanocatalysts' quantum size impacts their catalytic activity, hence surface area in nanomaterials plays a key role in controlling the charge transferring. Since multi-walled carbon nanotubes (MWCNTs) possess a large surface area as compared to bulk activated carbon (AC), thus their role in photo fermentative biohydrogen production (PFHP) from corn stover has been investigated. The physio-optical characteristics of the studied MWCNTs, and AC were characterized through the Brunauer Emmett Teller (BET), scanning electron microscope (SEM), and Raman spectroscopy. The experimental finding revealed that MWCNTs has a larger specific surface area (SSA) of 227.69 m 2 /g than activated carbon (AC) (126.26 m 2 /g). SEM and Raman results confirmed that MWCNTs have smaller sizes and more defects due to surface dangling bonds. The incorporation of MWCNTs in a photo fermentative medium showed a pronounced effect on hydrogen production. The optimal concentration of 20 mg/L MWCNTs increased the hydrogen production rate to 132.96 mL/h, 46.66% and 17.85% greater than the control group (CG) and AC, respectively, and reduced the lag period by 12 h. At 20 mg/L loading concentration, total hydrogen production was 293.84 mL, 2-fold and 16.24% greater than CG. The 44.85%, 100.39%, and 126.49% increase in byproducts, energy conversion efficiency (ECE), and light conversion efficiency (LCE), respectively compared to CG indicated an increase in metabolic processes, which increased total hydrogen production, suggesting that catalyst surface area is the key parameter affecting fermentative biohydrogen production catalytic efficiency.

The triggering effects of nickel ferrite (NiFe 2 O 4 ) photo nanocatalysts on photo fermentative hydrogen production (PFHP), and metabolic pathways under various excitation sources (incandescent lamp, Xenon lamp, and 532 laser) have been investigated. Compare to the control group (CG) highest cumulative hydrogen volume (CHV) and the maximum hydrogen production rate (HPR) of 568.8 mL and 9.17 mL/h, respectively were achieved at a loading centration of 150 mg/L excited with an incandescent lamp. The change in metabolites with NiFe 2 O 4 incorporation suggests that bacterial activity is significantly affected by photo nanocatalysts. Triggering of NiFe 2 O 4 by laser excitation showed the highest HPR of 7.83 mL /h within 24 h, which greatly reduces the lag time. The microbial community investigation showed that the addition of NiFe 2 O 4 photo nanocatalysts and the change of light source effectively improved the microbial community structure and increased the abundance of hydrogen-producing bacteria (HPB) which leads to enhanced hydrogen production.

In this study, titanium dioxide/activated carbon fiber (TiO 2 /ACF) was synthesized by liquid-phase deposition method and the effect of TiO 2 /ACF on the performance of photo-fermentation biohydrogen production (PFHP) from corn stover under visible light catalysis was discussed. Results show the maximum cumulative hydrogen yield (CHY) obtained under the optimal conditions was 74.0 ± 1.3 mL/g TS with TiO 2 /ACF addition of 100 mg/L, which was twice that without TiO 2 /ACF addition (36.9 ± 1.0 mL/g TS). Initial pH value had the most significant effect on CHY. The addition of TiO 2 /ACF promoted the metabolic pathway of nitrogenase to reduce H + produced by consuming acetic acid and butyric acid to hydrogen, and also shortened the photo-fermentation period. By scanning electron microscopy and X-ray diffraction analysis, the morphology and phase structure of TiO 2 /ACF after PFHP did not change significantly. This study laid the foundation for the reuse of TiO 2 and its practical application in PFHP.

This study examines photo-fermentative biohydrogen production (PFHP) from Arundo donax L. using binary (SiC/ZnO) and ternary (SiC/ZnO/SnO 2 ) co-catalyst systems. The maximum cumulative hydrogen production of 110 mL/g and hydrogen production rate of 39.74 mL/g·h⁻¹ at 24h was achieved in ternary-C2 group of ternary system which was 73.23% higher as compared to the CG (63.5 mL/g), also outperforms binary system (97.58 mL/g, 35.81mL/g·h⁻¹) by 12.73% and 10.97%. The binary system achieved a 48.67% hydrogen content percentage, while the ternary system had 52.53%, which is 14% and 18.3% higher than the control group. Multi-interface heterojunctions occur synergistically, which is the source of the increased activity. In addition to accelerating electron migration and inhibiting electron–hole recombination, this arrangement facilitates effective interfacial charge transfer. Together, these effects produce a favourable redox environment that improves bacterial metabolism and sustains a process of hydrogen production. Maximum light absorption and charge-separation efficiency may explain the ternary system's faster metabolism and microbial activity. Ternary system hydrogen production enhanced the charge transfer by reducing the oxidation-reduction potential (-408 mv) and lag phase reduced to 8.48h from 14.71h in binary system, a 53.73% performance boost. Maximum Energy Conversion Efficiency of 8.1% was achieved in experimental group ternary-C2 of ternary system which is 12% and 52.83% better than binary system (7.2%) and control (5.3%). The ternary system provides a better hydrogen production metabolite route and reduces VFA’s accumulation.

Photo-fermentation offers a promising roadmap for hydrogen production through their ability to harness light energy, however, its lower conversion efficiency is the major bottleneck for its realization. This study investigates the catalytic role of wideband gap nano-photocatalysts (SiC, ZnO, and SnO 2 ) in enhancing hydrogen generation from Arundo donax L. Physio-optical characteristics of SiC, ZnO, and SnO 2 nano-photocatalysts were assessed through SEM, XRD, and FT-IR which confirmed that incorporated nano-photocatalysts are spherical with uniform size distribution and there is no secondary phase. Hydrogen production experiments with varying nano-photocatalyst concentrations revealed that the maximum hydrogen yield of 104 and 98.83 mL/g was achieved with SiC and ZnO, respectively, at loading concentration of 200 mg/L, whereas 69.30 mL/g were observed with 100 mg/L of SnO 2 . The incorporation of SIC, ZnO, and SnO 2 nano-photocatalyst permitted to increase the hydrogen content in overall gas production by 41 %, 37.34 %, and 18.26 % as compared to the control group. The increase in hydrogen production is related to the enhanced e-h pair separation lifetime of SiC, confirmed from PL spectroscopy. Addition of SiC caused a longer availability of electrons that helped to increase the metabolic rate by 38 % and 40.29 % in energy conversion efficiency (ECE). ANOVA results revealed significant differences between the control and maximum values of CHP, HC%, byproducts, and ECE. Tukey pairwise comparisons showed that SiC and ZnO had non-significant differences at 200 mg/L but both significantly outperformed SnO 2 at 100 mg/L. Thus, the selection of suitable catalysts photocatalysts with enhanced e-h pair separation lifetime may offer promising prospects for sustainable energy technologies by enhancing biohydrogen production.
