Photocatalytic reduction of CO2 over Bi2WO6 in a continuous-flow differential photoreactor: Investigation of operational parameters

Polar semiconductor photocatalysts with intrinsic electric fields for selective organic transformation

“…Furthermore, Bi 2 WO 6 also has a favorable conduction band (CB) potential, which makes it an appropriate catalyst for CO 2 reduction. 94 Ribeiro et al 95 systematically studied the process parameters of the CO 2 photoreduction reaction using Bi 2 WO 6 to investigate the relationship between the photocatalytic activity and three process parameters (light intensity, partial pressure of H 2 O, and photocatalyst amount). The results showed that the CO 2 flow rate had an impact on CO 2 photoreduction.…”

Recent advances in constructing heterojunctions of binary semiconductor photocatalysts for visible light responsiveCO2reduction to energy efficient fuels: A review

“…A photo-reactor is designed based on a cautious assessment of the elements, which can impact the reactor execution such as light source, mathematical arrangement to oblige light, material of development, and thermal heat exchange. 19,20 A proficient photo-reactor ought to have high collectively of photons. The photo-reactor vessel can be worked from various materials such as stainless steel, 361 Pyrex, 362 and Quartz.…”

“…As a result, researchers have been working on improving activity of CO 2 reduction by exploring different photocatalysts and reactors. Although, many review papers discussing different enhancement strategies such as doping, coupling, heterojunctions, nanomaterials, and cocatalysts have been published, [19][20][21][22][23][24][25] few papers address other factors such as separation mechanisms, thermodynamics, scavengers, and intermediates, which are currently relevant for the understanding of photocatalytic activity. This work is focused on the latest developments of semiconductors used for CO 2 reduction to produce fuels as a renewable energy source.…”

Investigating the interfacial properties of halide perovskite/TiOx heterostructures for versatile photocatalytic reactions under sunlight

“…Photochemical reactions to decrease the amounts of CO 2 or water pollutants have been achieved using various materials such as metal oxides ( e.g. , TiO 2 , Cu 2 O, WO 3 , Bi 2 WO 6 , Zn 2 GeO 4 , ZnGa 2 O 4 , oxide perovskites), 9–11 metal–organic frameworks, 12 nitrides ( e.g. , C 3 N 4 , GaN, (Zn 1+ x Ge)(N 2 O x )), 13 sulfides ( e.g.…”
