Graphene role in improved solar photocatalytic performance of TiO2-RGO nanocomposite

Tailoring Interfacial Physicochemical Properties in Cu2O-TiO2@rGO Heterojunction: Insights from EXAFS and Electron Trap Distribution Analysis

“…To align the Fermi energy levels, when TNF and rGO form a heterojunction, electrons from the CBM of TNF tend to transfer to rGO more readily due to the larger work function of rGO (ϕ = 5.01 eV) than that of TNF (ϕ = 4.98 eV). Furthermore, the excellent conductivity of rGO ensured a fast charge transport rate and effective electron–hole pair separation, reducing the recombination rate of charge carriers which is in good agreement with the previous literature …”

Utilizing the Built‐in Electric Field of p–n Junctions to Spatially Propel the Stepwise Polysulfide Conversion in Lithium–Sulfur Batteries

“…[15] For the Ti 2p spectrum of p-Co 3 O 4 /n-TiO 2 -HPs (Figure 2f), two peaks located at 459.4 (Ti 2p 3/2 ) and 464.9 eV (Ti 2p 1/2 ) are attributed to Ti 4+ whereas the peaks at 460.6 and 466.2 eV are attributed to Ti-O-C bonds. [16] Two additional peaks attributed to Ti 3+ are observed at 458.7 and 463.8 eV, [17] indicating the presence of oxygen defects in TiO 2 species.…”

Biomass-derived graphene modified γ-Fe2O3/N,Fe–TiO2@GO: a prolific photoactive material with extended visible to near IR harvesting

“…35 where k is the apparent rate constant determined by plotting ln( C 0 / C t ) versus time and the rate constant was calculated from the slope of the straight line. 36 Fig. 8b shows the linear kinetic curves of the mixed dye degradation in different reaction systems.…”
