A Versatile Nb2O5/SnO2 Heterostructure for Different Environmental Purposes: Water Treatment and Artificial Photosynthesis

“…All the contaminants solution was used without pH correction. The CO 2 photoreduction was performed as outlined in the literature [54] . The reactions were carried out in a liquid medium and the products collected in the headspace.…”

Soft template-assisted copper-doped sodium dititanate nanosheet/graphene oxide heterostructure for photoreduction of carbon dioxide to liquid fuels

“…10,18,19,23,31 The minor peaks at 54.4 , 63.1 , 69.4 , and 75.5 can also be ascribed to anatase TiO 2 . 7,18 A small peak at 30.6 corresponds to a weak signal of brookite TiO 2 . 10 Fig.…”

“…3(a)) reveal diffraction peaks at 25.3 , 38.0 , and 48.0 (2q), which can be interpreted as (101), (004), and (200) lattice planes of the anatase TiO 2 . 10,18,19,23,31 The minor peaks at 54.4 , 63.1 , 69.4 , and 75.5 can also be ascribed to anatase TiO 2 . 7,18 A small peak at 30.6 corresponds to a weak signal of brookite TiO 2 .…”

“…9 Photoreduction of CO 2 to liquid fuels is an attractive alternative that relies on photocatalysts such as zinc oxide (ZnO), 3,10 cadmium sulde (CdS), 2 and titanium dioxide (TiO 2 ). 5,6,[10][11][12][13][14][15][16][17][18][19] TiO 2 is a popular photocatalyst that has been used in the decomposition of organic pollutants in wastewater. It has also featured heavily as a potent photocatalyst for CO 2 conversion.…”

MoS2–Nanosheets-Based Catalysts for Photocatalytic CO2 Reduction: A Review

“…In a photocatalytic CO 2 reduction, the photocatalyst governs the kinetics and the thermodynamics of redox reactions, to overcome the associated obstacles of the preliminary modification steps. The energy of the excited electrons is primarily dependent on the optical properties of photocatalyst; the CO 2 reduction product selectivity is majorly governed by the variable interactions of an intermediate species with the catalyst surface. − In regard to this, the feasibility of a photocatalyst to achieve the maximum output in CO 2 photocatalytic reduction should follow certain criteria: the first step is the interaction of substrate molecules (CO 2 , H 2 O) with the catalyst surface to initiate the transformation process. Apart from a substrate adsorption, a photon absorption is another governing factor, as it excites the electrons from the valence band (VB) to the conduction band (CB) of the catalyst.…”
