Improvement of Cr (VI) photoreduction under visible-light by g-C<inf>3</inf>N<inf>4</inf> modified by nano-network structured palygorskite
2019, Chemical Engineering JournalCitation Excerpt :As shown in Fig. 5(d), apparently, the Cr (VI) reduction efficiencies are much higher at pH = 2 than those at 4, 6, 8 and 10. Hence, the suitable pH of photo-reduction of Cr (VI) in our work was recommended as pH = 2 and further experiments were all conducted at this pH, which is in accordance with the previous findings [70–72]. In order to test the IPAL/CN catalyst reusability, the data for IPAL/CN which was continuously tested 100 min for 4 runs is shown in Fig. 6.
Highly efficient heterostructured stannic disulfide/stannic anhydride hybrids: Synthesis, morphology, and photocatalytic reduction of chromium (VI) under visible light
2018, Journal of Colloid and Interface ScienceCitation Excerpt :Previous studies reported that introducing sacrificial electron donors into a photocatalytic reduction system was beneficial for promoting photocatalytic performance [21,44]. Formic acid, with a simple molecular structure, was suitable for use as a sacrificial electron donor because its oxidation was straightforward with only minimal intermediates produced [45,46]. Thus, the photocatalytic reductions of Cr(VI) over the S5 sample with different amounts of formic acid added were investigated.
Novel application of metal-free graphitic carbon nitride (g-C<inf>3</inf>N<inf>4</inf>) in photocatalytic reduction - Recovery of silver ions
2016, Journal of Environmental Chemical EngineeringCitation Excerpt :The presence of formic acid in the system enhanced the photoreduction of Ag+ ions and the enhancement was observed to be dependent on the formic acid concentration. This enhancement is due to the straightforward oxidation of formic acid, with minimal intermediate products, to carbon dioxide [34]. This oxidation reaction consumed the photogenerated holes that lead to charge separation in g-C3N4 photocatalyst.
Photocatalytic reduction of nitrate in seawater using C/TiO<inf>2</inf> nanoparticles
2016, Journal of Photochemistry and Photobiology A: ChemistryCitation Excerpt :In this study, formic acid was selected as a sacrificial reagent for suppressing the electron/hole recombination mechanism (Fig. 8). Since it has a simple molecular structure with only one carbon, therefore its oxidation to CO2 is straightforward and involves minimal intermediate products [53,54]. In the presence of formic acid, the reduction of nitrate can be expressed as follows:C/TiO2 + hν → e− + h+NO3− + 2e− + H2O → NO2− + 2OH−NO2− + 6e− + 7H+ → NH3 + 2H2O2NH3 → N2 + 3H22HCOO− + h+ → CO2 + CO2 − + H2
Efficient photocatalytic reduction of aqueous Cr(VI) over CaSb <inf>2</inf>O <inf>5</inf>(OH) <inf>2</inf> nanocrystals under UV light illumination
2012, Applied Catalysis B: EnvironmentalCitation Excerpt :In this study, formic acid with its simple one-carbon molecular structure was chosen as a hole scavenger and its effect on Cr(VI) reduction was investigated. Its oxidation to carbon dioxide is straightforward and involves minimal intermediate products [22,23]. Also, formic acid is capable of forming reducing radicals, which can help in the reduction reaction [24].
