Mechanism investigation of PtPd decorated Zn0.5Cd0.5S nanorods with efficient photocatalytic hydrogen production combining with kinetics and thermodynamics

Visible-light-driven photocatalytic N2 fixation to nitrates by 2D/2D ultrathin BiVO4 nanosheet/rGO nanocomposites

“…3b shows the surface photovoltage (SPV) spectra of the BVO and BG-1 samples, the clear response in the wavelength range from 300 to 500 nm corresponding to the bandgap of BiVO 4 . 32 Meanwhile, the higher SPV for the BG-1 composite sample implies that an increased number of photogenerated holes migrated to the surface of BG-1 and high momentum electrons were motivated. 33…”

Improving the Performance of Photocatalytic Hydrogen Production through Adjusting the Size of Defective Quantum Dots Co‐Catalyst Affected by Intramolecular Steric Hindrance on Thermal Stability of Functional Groups

“…When the CB potential of the semiconductor is below the potential formed by •O 2 − (i.e.,−0.33 vs. SHE, pH = 7), the O 2 − radical generated by the reaction of O 2 with photogenerated electrons can be as a probe. [ 39 ] •O 2 − was quantified by electron paramagnetic resonance (EPR) analysis using 5, 5‐dimethyl‐L‐pyrrolidine N‐oxide (DMPO) as the trapping agent. Figure 7f further explores the differences in electron injection in different materials, the concentration of •O 2 − was measured by EPR when the light was 5 min.…”

α-NiS–β-NiS growth on Cd0.5Zn0.5S formed Schottky heterojunctions for enhanced photocatalytic hydrogen production

“…The reason is that the BE shift is closely relevant to the chemical valence, chemical circumstances and charge distribution of the elements and the increased BE value resulted from the decrease of electron density. [35][36][37][38][39] Through electron paramagnetic resonance (EPR) tests, the origin of the interaction between the Cd 0.5 Zn 0.5 S and NiS was investigated. 40 Pure Cd 0.5 Zn 0.5 S had a strong signal peak, indicating that there were a lot of S defects on the Cd 0.5 Zn 0.5 S at this time, as shown in Fig.…”
