Abstract

A mechanistic schematic diagram of the occurred reactions in the photoreaction; the Pd–TiO2 plasmonic photocatalysts demonstrate promising dual functional materials generation of helpful fuel gases from the destruction of organic matter.

Eu3+:Y2Ti2O7 nanomaterials as efficient photocatalysts used for hydrogen and biogas production toward a sustainable environment

“…Asal et al 1 investigated effect of lanthanide doped TiO 2 on the photocatalytic production of useful hydrocarbon from acetic acid. First research results concerning solar hydrogen and methane production from wastewater using Pd/TiO 2 and Pd/ZnO were published by our research group 5,6 . All the more, no attempts of using Y 2 Ti 2 O 7 and Eu 3+ /Y 2 Ti 2 O 7 in a photocatalytic generation of biogas and hydrogen can be found among literature data.…”

“…Renewable and clean energy resources are crucially important for industrial and economic development. Biogas and hydrogen are considered promising economic, energy‐efficient, and environmentally friendly fuels 1–6 . There are various gases in biogas, namely, methane, carbon dioxide, and others.…”

“…Finally, the toxic organic resources such as herbicides and pesticides are dangerous for reaction based on anaerobic bacteria. 1,5,6 Photocatalytic method can overcome the traditional method limitation and seems to be more sustainable. 4 The photocatalytic method that depends on nano-photocatalysts can be applied for any type of organic resources regardless of its toxicity.…”

“…1 Therefore, the production of hydrogen and biogas as a source of energy from organic matter using nano-photocatalyst has attracted the attention of researchers. 1,[4][5][6][7][8][9][10][11][12][13][14][15] One of the most often used photocatalysts is pyrochlore. Pyrochlore has the general formula A 2 B 2 O 7 with Fd3m space group, which results in eight formula units in a face-centered cubic unit cell.…”
