“…4,5 Similar to the Fenton system, using iron-containing materials as catalysts still presents challenges including ineffective reduction and ferrikinetics of trivalent iron, resulting in the enrichment, hydrolysis, and precipitation of Fe(III), ultimately leading to the formation of hazardous iron sludge waste. 6 Consequently, the development of a controllable PAA advanced oxidation system remains highly challenging.…”

“…One of the simplest coordination polymers, ferrous oxalate, has a one-dimensional chain structure consisting of Fe 2+ and C 2 O 4 2− ions [7]. There are several reports wherein these FeC 2 O 4 complexes are used for various photocatalytic applications [8][9][10]. These FeC 2 O 4 complexes were produced using chemical reagents rather than naturally occurring iron ore.…”

In this study, iron oxalate dihydrate (FOD-ore) was produced from iron ore by the process using oxalic acid to extract iron, followed by photo-reduction. Several techniques, such as X-ray powder diffraction (XRD), Raman, scanning electron microscopy with energy dispersive X-Ray analysis (SEM-EDX), ultraviolet–visible diffuse reflectance spectroscopy (UV-DRS), photoluminescence spectroscopy (PL), and X-ray photoelectron spectroscopy (XPS), were used to determine the physicochemical properties of the FOD-ore sample. To compare the photocatalytic activity of FOD-ore, commercial hematite (Fe2O3) was used as a precursor to creating iron oxalate (FOD). The FOD-ore was applied to the photocatalytic degradation of rhodamine B (RhB), a model organic pollutant in wastewater. Using the produced FOD-ore, we were able to degrade more than 85% of RhB within 90 min at a rate approximately 1.4 times higher than that with FOD. FOD-ore demonstrated greater light absorption than FOD, resulting in improved RhB degradation performance. Moreover, the enhanced separation and transport of photogenerated electron-hole pairs can be attributed to the increased photocatalytic RhB degradation rate of FOD-ore, confirmed by photoluminescence results. Therefore, FOD-ore can be utilized as a potential photocatalyst in the degradation process for other organic pollutants under light irradiation.

The rational design of visible‐light‐responsive catalysts is crucial for converting solar energy into hydrogen energy to promote sustainable energy development. In this work, a C─S─C bond is introduced into g‐C3N4 (CN) through S doping. With the help of the flexible C─S─C bond under specific stimuli, a hollow coral‐like porous structure of S‐doped g‐C3N4 (S‐CN) is synthesized for the first time. And an S‐doped g‐C3N4/ZnIn2S4 (S‐CN/ZIS) heterojunction catalyst is in situ synthesized based on S‐CN. S0.5‐CN/ZIS exhibits excellent photocatalytic hydrogen evolution (PHE) efficiency (19.25 mmol g−1 h−1), which is 2.7 times higher than that of the g‐C3N4/ZnIn2S4 (CN/ZIS) catalyst (8.46 mmol g−1 h−1), with a high surface quantum efficiency (AQE) of 34.43% at 420 nm. Experiments and theoretical calculations demonstrate that the excellent photocatalytic performance is attributed to the larger specific surface area and porosity, enhanced interfacial electric field (IEF) effect, and appropriate hydrogen adsorption Gibbs free energy (ΔGH*). The synergistic effect of S doping and S‐scheme heterojunction contributes to the above advancement. This study provides new insights and theoretical basis for the design of CN‐based photocatalysts.
