The Tuning of Rutile-Tio2 with Pd/Rb2o Cocatalysts for Water Splitting: Escalating Sun-Light Driven Photocatalytic Hydrogen Production

Simultaneous elimination of toxic dyes, ciprofloxacin and Cr(vi) contents from polluted water: escalating surface plasmon electrons of Ag cocatalysts on BiVO4 microstructures

“…The 3-D images are illustrated in Fig. 5d and e which reveal the surface roughness 47 and morphology with higher density of active sites in Ag-BiVO 4 photocatalysts.…”

“…where η represents the % removal efficiency and C 0 and C are the initial and final concentrations. Similarly, the kinetics of the degradation reactions was measured via eqn (2) 46,47 ln…”

“…When the Ag-BiVO 4 photocatalyst was exposed to the sunlight, electrons present in the VB are excited and move to the CB of catalyst. 47,79,80 During the photoreaction, Ag contents produce SPR electrons that as a result increase the electron population over the surfaces of the catalyst. 18 Meanwhile, a Schottky barrier was developed on the edge of Ag metal and the BiVO 4 surface.…”

Insight into the development and proceedings of Au@Al–CeVO4 catalysts for water splitting: an advanced outlook for hydrogen generation with sunlight

“…Under sunlight irradiation, Au@Al-CeVO 4 absorbs photons and generates electrons and holes in the conduction band and valence band of the semiconductor, respectively. [57][58][59] The photogenerated electrons in the conduction band of the semiconductor react with water molecules adsorbed onto their active sites to form hydroxyl radicals (˙OH) and hydrogen ions (H + ). These produced (H + ) ions are converted into H 2 as a result of a catalytic reduction reaction at active centres of the catalyst.…”

Positioning hydrogen reaction sites by constructing CdS/CoNiMoS4 heterojunctions for efficient photocatalytic hydrogen evolution

“…However, CdS-like single-semiconductor materials exhibit numerous limitations, notably the quick electron-hole pair recombination, sluggish charge transfer, and photocorrosion, which may drastically reduce the photocatalytic evolution rate. [5][6][7] To date, tremendous efforts have been made to tackle the issues of CdS nanostructures as a photocatalyst, which include loading metal cocatalysts, 8 surface engineering, 9 metal or ion doping, 10,11 heterojunction formation, 12,13 and facet engineering. 14,15 According to the earlier studies, noble metals with low overpotentials can function as hydrogen evolution cocatalysts.…”
