Regulating the photoelectrocatalytic reduction efficiency of CO2 to syngas via SnO enhanced g-C3N4 based p-n heterojunction

Water-stable perovskite CsPb2Br5/CdSe quantum dot-based photoelectrochemical sensors for the sensitive determination of dopamine

“…Typically, the type of semiconductor is determined based on the positive or negative slope of the Mott–Schottky curve. 41 The positive slope for CdSe indicates its characteristics as an n-type semiconductor, while the negative slope for CsPb 2 Br 5 suggests a p-type semiconductor behavior (Fig. 3a and d).…”

Metal–organic frameworks (MOFs) for photoelectrocatalytic (PEC) reducing carbon dioxide (CO2) to hydrocarbon fuels

“…42 Graphite phase carbon nitride (g-C 3 N 4 ) has a wide light absorption range and exceptional thermal and chemical stability. 45–49 Jiang et al used the prepared g-C 3 N 4 with a lamellar structure on the photocathode to study its catalytic reduction ability of CO 2 to methanol. 50 Low quantum efficiency and small specific surface area greatly limit the improvement of the catalytic performance.…”

Light Control-Induced Oxygen Vacancy Generation and In Situ Surface Heterojunction Reconstruction for Boosting CO2 Reduction

“…The photocatalytic CO 2 reduction has attracted more and more attention. Up to now, many semiconductor-based materials, such as ZnO, GaN, ZrO 2 , Bi 2 WO 6 , TiO 2 , and C 3 N 4 , have been developed as functional catalysts for photocatalytic CO 2 reduction, proving that CO 2 can be converted into CO, CH 4 , methanol, and other valued chemicals using H 2 O sacrificial agent [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. After decades of exploration and development, many excellent achievements have been obtained, but the practical application of photocatalytic CO 2 reduction is severely limited by the low activity and the poor stability of the existing catalysts.…”
