“…To enhance its photocatalytic properties the NPs of metal oxides (doping agents) have been frequently used as cocatalysts for a long time. For instance, a small amount (even less than 1.0 wt.%) of some noble metals, e. g. Pt, Pd, Ag, Au, Ru, Rh, and Ni [88–94] can improve H 2 evolution compare to bare TiO 2 or another semiconductor (La‐CNT, CdS, g‐C 3 N 4 , ZnO, Bi 2 O 3 , WO 3 ) [91,95–97] . In addition, some research have been focused on the formation of Z‐scheme systems, i. e. composites consisting more than one semiconductor [97] .…”

Nowadays, the pursuit of a circular economy and sustainability pushes the world's efforts toward less fossil fuel‐dependent energy production strategies. The sense of sustainability, thus, means searching for effective approaches involving ecological fuels, and processes with a little environmental concern. Approaches for utilization of such renewable resources like solar energy as a driving force, and biomass‐derived compounds as feedstocks for simultaneous hydrogen production as the most promising energy carrier, are currently gaining their momentum as the solutions for sustainable energy generation and tackling climate change. In this paper, we review the scientific advances in photocatalytic hydrogen production from biomass‐derived compounds via wet‐ and dry‐ photoreforming over metal‐loaded‐semiconductor photocatalysts. Based on the recent literature reports, we narrowed focus particularly to designing the state‐of‐the‐art photocatalysts which renders substantial enhancement of their performance possible via localized surface plasmon resonance effect.

“…Hydrogen formation in reforming reaction mainly deals with the splitting of water into H + and O 2 ions, further reforming of alcohols into H + and CO 2, respectively. 52 Presence of hydrogengenerating compounds in HTL-AP results in uppermost hydrogen formation. Degradation or exhaustion of hydrogen-generating compounds in the HTL-AP resulted in lesser hydrogen production at uppermost reaction time.…”

In this study, green fuel (hydrogen energy) was produced from the aqueous phase obtained from the hydrothermally liquefied Nostoc ellipsosporum biomass via photo-catalytic reforming. Initially, algae were cultivated in municipal wastewater and fog medium (80:20) in photo bio-reactor for biomass production. Later the algae biomass was liquefied under varying temperature of 220 C to 320 C at 5Mpa for 60 min. From the results, it was seen that the maximum bio-oil yield was 31 wt% for biomass to solvent ratio of 0.05 g/mL at 300 C. Gas Chromatography-Mass Spectroscopy (GC-MS) analysis of bio-oil showed the presence of hydrocarbons like octadecane, heptadecane, etc. Aqueous phase comprised of hydrogen generating low molecular weight compounds. Photo-catalytic reforming process with 0.1 g of TiO 2 catalyst at time of 2 h resulted in hydrogen yield of 27 wt%. Catalyst reusability study resulted in cumulative hydrogen yield of 76 wt% from five consecutive cycles.

“…In this case, the mechanism of improving charge transfer to the sites of redox half-reactions is also achieved by adding phosphate anions to the electrolyte. In fact, the use of various electrolytes, such as glycerol-water mixture [ 168 ], in its effect on the parameters of the transferred charges between photocatalytic coatings and a split liquid. Varieties of compositions of working electrolytes and a list of structural heterojunctions, as well as geometric schemes that receive the influence and influence of all this on the photoresponse of PEC systems are shown in Table 2 .…”

This review focuses on tungsten oxide (WO3) and its nanocomposites as photoactive nanomaterials for photoelectrochemical cell (PEC) applications since it possesses exceptional properties such as photostability, high electron mobility (~12 cm2 V−1 s−1) and a long hole-diffusion length (~150 nm). Although WO3 has demonstrated oxygen-evolution capability in PEC, further increase of its PEC efficiency is limited by high recombination rate of photogenerated electron/hole carriers and slow charge transfer at the liquid–solid interface. To further increase the PEC efficiency of the WO3 photocatalyst, designing WO3 nanocomposites via surface–interface engineering and doping would be a great strategy to enhance the PEC performance via improving charge separation. This review starts with the basic principle of water-splitting and physical chemistry properties of WO3, that extends to various strategies to produce binary/ternary nanocomposites for PEC, particulate photocatalysts, Z-schemes and tandem-cell applications. The effect of PEC crystalline structure and nanomorphologies on efficiency are included. For both binary and ternary WO3 nanocomposite systems, the PEC performance under different conditions—including synthesis approaches, various electrolytes, morphologies and applied bias—are summarized. At the end of the review, a conclusion and outlook section concluded the WO3 photocatalyst-based system with an overview of WO3 and their nanocomposites for photocatalytic applications and provided the readers with potential research directions.
