“…Photocatalytic reforming of further organic molecules, such as aldehydes [111,112], carboxylic acids [113,114], cellulose [115] and azodyes [116], has been also reported in the literature review. An extensive classification of organic compounds that could be used as sacrificial agents has been recently drawn up [14].…”

Photocatalytic water splitting and organic reforming based on nano-sized composites are gaining increasing interest due to the possibility of generating hydrogen by employing solar energy with low environmental impact. Although great efforts in developing materials ensuring high specific photoactivity have been recently recorded in the literature survey, the solar-to-hydrogen energy conversion efficiencies are currently still far from meeting the minimum requirements for real solar applications. This review aims at reporting the most significant results recently collected in the field of hydrogen generation through photocatalytic water splitting and organic reforming, with specific focus on metal-based semiconductor nanomaterials (e.g., metal oxides, metal (oxy)nitrides and metal (oxy)sulfides) used as photocatalysts under UVA or visible light irradiation. Recent developments for improving the photoefficiency for hydrogen generation of most used metal-based composites are pointed out. The main synthesis and operating variables affecting photocatalytic water splitting and organic reforming over metal-based nanocomposites are critically evaluated.

“…Various examples have been reported about water solutions containing various alcohols, for example, 2-propanol [214], acids [215,216], and aldehydes, such as formaldehyde and acetaldehyde [194,217]. LaNiO 3 -based catalysts were active under visible light for the PR of formaldehyde [194], while the degradation of azodyes was performed with simultaneous H 2 production over Pt-TiO 2 [218].…”

This paper focuses on the application of photocatalysis to hydrogen production from organic substrates. This process, usually called photoreforming, makes use of semiconductors to promote redox reactions, namely, the oxidation of organic molecules and the reduction of H + to H 2 . This may be an interesting and fully sustainable way to produce this interesting fuel, provided that materials efficiency becomes sufficient and solar light can be effectively harvested. After a first introduction to the key features of the photoreforming process, the attention will be directed to the needs for materials development correlated to the existing knowledge on reaction mechanisms. Examples are then given on the photoreforming of alcohols, the most studied topic, especially in the case of methanol and carbohydrates. Finally, some examples of more complex but more interesting substrates, such as waste solutions, are proposed.

“…In the recent time, perovskites have increasingly been synthesized by combustion of the gel-like precursors obtained through evaporation of aqueous solutions containing nitrates of the desired metals and various organic compounds [3][4][5][6][7][8][9][10][11][12]. The organic component, typically represented by glycine [6,8,10,12], citric acid [7,9,11], ethylene glycol [8] (or ethylene glycol with citric acid [5,11]), urea [4] and others [3], serves several purposes.…”

“…This leads to a high dispersion of the forming perovskite particles [8,12,14]. A step of calcination of the oxide residue left after the combustion is usually required to complete the phase formation process [3][4][5][7][8][9][10][11][12] and decompose the thermodynamically stable phase of lanthanum carbonate [4,5,9,12,16]. Nevertheless, on the whole, the use of organometallic precursors in combustion-based perovskite syntheses shows obvious advantages over the conventional ceramic methods involving time-and energy-consuming steps of sintering (with intermediate steps of grinding) of a mixture of inorganic salts or oxides [17][18][19].…”
