Photocatalytic N 2 conversion to ammonia using efficient nanostructured solar-energy-materials in aqueous media: A novel hydrogenation strategy and basic understanding of the phenomenon

CO2 conversion into methanol under ambient conditions using efficient nanocomposite photocatalyst/solar-energy materials in aqueous medium

“…This evidence proposes the conjecture that during the water splitting process, not only more hydrogen but more hydroxyl could also be transiently generated upon the ternary photocatalyst surface. 10 With the generation of more H/OH radicals and facilitation of the hydrogenation of methoxyl or hydroxylation of methyl radicals (eqn (7)), the production of greater quantity of methanol (Fig. 6) is rationalized: 11,[39][40][41] a,b data listed in these parentheses (rows) denote respectively to the selectivity (%) and energy efficiency (%), obtained for the photoconversion process to produce a specic product upon the photocatalyst material.…”

Insights into the Recent Progress and Advanced Materials for Photocatalytic Nitrogen Fixation for Ammonia (NH3) Production

“…In a continuous work of previous studies, further investigations of mechanism on iron titanate photocatalyst were conducted by Rusina [38] and Krich [39] The electron transfer system of photo(electro)catalytic N 2 reduction on the Fe 2 Ti 2 O 7 thin film includes a series of processes of nitrogen-diazene-hydrazine-ammonia-nitrate. Moreover, Lashgari proposed a N 2 photofixation mechanism based on H-atom production [40]. In addition to Fe doped metal oxide materials, non-metal oxide semiconductors were modified with iron.…”

Progress of Metal Oxide (Sulfide)-Based Photocatalytic Materials for Reducing Nitrogen to Ammonia

“…Interestingly, Augugliaro et al [44] supported Fe 2 O 3 -hybridized TiO 2 on Al 2 O 3 as photocatalyst which was applied in gas-solid uidized bed reactors to improve NH 3 yields because of the in uence of iron ions on the TiO 2 crystalline [45]. Lashgari and Zeinalkhani [21] photosynthesized NH 3 in a H 2 O photosplitting setup in the presence of some synthetic Fe 2 O 3 and TiO 2 -based uniform nanoparticles and obtained the maximum NH 3 yield. Bourgeois et al [26] suggested that thermal pretreatments could generate surface defects or impurity states on the surface of unmodi ed TiO 2 that showed the photocatalytic activity of reducing N 2 after annealing in air.…”
