Photocatalytic CO 2 reduction with H 2 O over LaPO 4 nanorods deposited with Pt cocatalyst

Photocatalytic reduction of CO 2 into methanol and ethanol over conducting polymers modified Bi 2 WO 6 microspheres under visible light

“…A c c e p t e d M a n u s c r i p t 12 as HCHO and HCOOH were detectable in the liquid phase. Furthermore, no gas products such as CH 4 and CO were observed because the conduction band (CB) potential of Bi 2 WO 6 is too low for CO 2 photoreduction.…”

“…Since then, many studies have been devoted to the semiconductor-based photocatalytic reduction of CO 2 with H 2 O, and the pace has increased enormously in the past decades. A wide range of photocatalysts, such as, V and N doped TiO 2 nanotubes [6], CeO 2 -TiO 2 composite [7], MgO-TiO 2 nanotubes network film [8], SiO 2 Pillared HNb 3 O 8 [9], g-C 3 N 4 /Pt composite [10], sulfur doped g-C 3 N 4 [11], Pt-loaded LaPO 4 [12], Ru- [13] and Ir-complex [14], and ZnGe 2 O 4 [15], have been exploited for the photocatalytic reduction of CO 2 to hydrocarbons. However, many effective photocatalysts are only sensitive to UV light, which only comprises a small fraction of solar energy that reaches the Earth"s surface.…”

Electrochemical reduction of bicarbonate on carbon nanotube-supported silver oxide: An electrochemical impedance spectroscopy study

“…Recycling CO2 into readily-transportable hydrocarbon fuels and valuable chemicals via photochemical, biochemical and electrochemical reduction methods, has increasingly gained attention as a solution to both the energy and environmental challenges of the world today [6,7]. Moreover, electrochemical reduction is a promising method, due to its operability under ambient reaction conditions and the ease of process control.…”

Fabrication of the heterostructured CsTaWO6/Au/g-C3N4 hybrid photocatalyst with enhanced performance of photocatalytic hydrogen production from water

“…In recent years, many studies have revealed that the modifying with noble metal nanoparticles is one of effective attempts that dedicated to growing the photocatalytic efficiency of semiconductor [25][26][27][28]. Noble metal loaded on photocatalyst can facilitate separation of photo-generated electron-hole pairs and transfer the electrons across a low resistance pathway at the interfacial region that in turn rises the surface reactivity [24,29,30].…”
