Efficient Electron Transfer across Strontium Titanate Decorated Graphene Oxide for High‐Performance Dye‐Sensitized Solar Cells and Photocatalytic Degradation of Dye and Antibiotic

“…The weaker peak at 1433 cm −1 was attributed to C−H bending vibration. It confirms the interaction of C−H groups, which might be evidence for a successful reduction of GO to rGO, was responsible for the composition of rGO and SrTiO 3 [44–46] . The wide absorption band at around 3000–3500 cm −1 is responsible for stretching vibrations of O−H group [47,48] .…”

“…It confirms the interaction of CÀ H groups, which might be evidence for a successful reduction of GO to rGO, was responsible for the composition of rGO and SrTiO 3 . [44][45][46] The wide absorption band at around 3000-3500 cm À 1 is responsible for stretching vibrations of OÀ H group. [47,48] These findings in detail support the development of the SrTiO 3 nanosphere on rGO sheet through TEM image.…”

Polymer-enhanced perovskite oxide-based photocatalysts: a review

“…Interestingly, pristine OPs have been extensively investigated for their potential photocatalytic applications. Thus, new significant studies have shifted into adding dopants into OPs, such as transition metals, 113,114 rare earth elements, 115,116 carbonaceous materials, 117,118 and polymers. 74,119 Polymers–OPs have demonstrated a great deal of promise for various applications.…”

Construction of NdFeO₃ nanoparticles on reduced graphene oxide for an enhanced visible light assisted-Fenton degradation of organic pollutant in oily wastewater

“…Many attempts have been made to overcome this by incorporating the perovskites onto/into suitable supports, such as silica [7], gC3N4 [8], zeolite [9], and graphene [10]. Among the various supports, graphene have been found to be promising for a photocatalytic system because of their high surface area, excellent hydrophobicity, high electrical and thermal conductivity, electron mobility, chemical stability and mechanical strength [11]. Reduced graphene oxide (rGO) sheets appear more advantageous than graphene because it can catalyze the generation of •OH owing to the oxygen containing functional groups (i.e., carboxyl, hydroxyl, and epoxy groups) on the layered rGO surfaces [12].…”
