Die photokatalytische Reformierung Lignocellulose‐haltiger Biomasse ist eine aufstrebende Methode zur Produktion von erneuerbarem H2. Dieser Prozess verbindet Photooxidation von Biomasse mit photokatalytischer Wasserstoffentwicklung bei Raumtemperatur und Atmosphärendruck. Die Umsetzung von Biomasse ist weniger energieaufwändig als Wasserspaltung und liefert dabei hochreinen H2, ohne dass sich O2 bildet. Die direkte Reformierung von unbehandelter Rohbiomasse birgt das Potenzial, weltweit lokal verfügbares Material als kostengünstige Energiequelle zu nutzen.

“…In order to improve the efficiency and keep the activities of semiconductors, it is necessary to add electron donors to the reaction systems (i.e., methanol, ethanol), which can react irreversibly with the photoinduced holes [11][12][13].…”

“…Due to the presence of polarity and its ability to donate the lone-pair electron, glycerol behave as a sacrificial reagent, also widely known as hole scavenger or electron donor, to prevent an unfavorable electron-hole recombination during the photoexcitation process [15]. The Pt nanoparticle as co-catalyst loaded on to La-doped NaTaO 3 nanocrystal was successfully synthesized via photo-deposition and a sol-gel method, respectively.…”

Abstract. Pt nanoparticles on La-doped sodium tantalum oxide (La0.02Na0.98TaO3), which acts as an active co-catalyst for H2 evolution under UV light irradiation was successfully synthesized by photo-deposition method. The La0.02Na0.98TaO3 photocatalyst was obtained by the reaction of La(NO3)2.3H2O, TaCl5, and NaOH at ambient temperature. The catalyst produced was characterized by a scanning electron microscope (SEM) and a high-resolution transmission electron microscope (HRTEM). SEM images of the La0.02Na0.98TaO3 sample showing that its particles size is ranging between 50-150 nm. The Pt particles are detected from HRTEM images is around 2-4 nm. The Pt/La0.02Na0.98TaO3 samples prepared were applied for photocatalytic H2 production at 30 o C. The photocatalyst performance was evaluated for hydrogen production from water combining with glycerol as an electron donor (sacrificial reagent). The reactions were carried out in a closed reactor with a gas circulation system, illuminated with mercury (Hg) lamp. The experimental results show that the presence of glycerol in the systems can not only improve the efficiency of photocatalytic hydrogen generation but can also be decomposed to hydrogen efficiently. The photocatalytic activity of La0.02Na0.98TaO3 is significantly enhanced when Pt was loaded onto its crystalline surface.

“…To do this, sacrificial reagents such as methanol [6], glucose [4] and sulfide ions [2] have been added to the aqueous suspension containing the photo catalyst. These reducing agents, that are also called Photocatalytic Hydrogen Production from Seawater Using CdxZn1-xS hole scavengers, are irreversibly oxidized by photogenerated holes.…”

Abstract-Hydrogengas has been shown to photocatalytically generated from pure water. With saltwater comprising 93% of the earth's water reservoir, methods to produce hydrogen from seawater minus the expensive water purification are desired. Cd 0.8 Zn 0.2 S has been proven as an effective photocatalyst for hydrogen production but it remains to be tested in seawater. This study provides proof of concept for hydrogen production from seawater using fresh and reused Cd 0.8 Zn 0.2 S upon irradiation with visible light and with the addition of sulfide/sulfite as sacrificial agents. The post-usage characteristics of Cd 0.8 Zn 0.2 S catalyst were investigated using SEM and FTIR. The rate of hydrogen gas production from seawater was up to six times faster than in distilled and simulated seawater for both fresh and reused catalyst. Reused catalyst showed reduced rates of gas accumulation. Catalysts exposed to non-distilled water showed marked changes in their SEM appearance and their spectral transmittance.
