Abstract In this study, Ag 2 CO 3 /SnFe O 4 (Ag /SFO) photocatalyst was prepared by a simple hydrothermal‐ultrasonic method for the efficient degradation of ciprofloxacin and phenol. The SFO nanoparticles were attached on surface rods synthesized low‐temperature precipitation method, resulting unique 1D/0D morphology, which increased number active sites. Due to introduction magnetic SFO, /SFO exhibited excellent recovery performance. When mass fraction 5%, efficiency composite highest, rate 6.5 1.5 times higher than pure , respectively. improved photoactivity should be attributed construction heterojunction with tight interface, boosts separation transfer photoinduced electron hole pairs. On basis experimental results, possible Z ‐scheme photocatalytic mechanism discussed. Additionally, photostability proved cycle experiment.

Rational Photodeposition of Cobalt Phosphate on Flower-like ZnIn2S4 for Efficient Photocatalytic Hydrogen Evolution

Molecules, Journal Year: 2024, Volume and Issue: 29(2), P. 465 - 465

Published: Jan. 17, 2024

The high electrons and holes recombination rate of ZnIn2S4 significantly limits its photocatalytic performance. Herein, a simple in situ photodeposition strategy is adopted to introduce the cocatalyst cobalt phosphate (Co-Pi) on ZnIn2S4, aiming at facilitating separation electron–hole by promoting transfer photogenerated ZnIn2S4. study reveals that composite catalyst has superior performance than blank In particular, loaded with 5% Co-Pi (ZnIn2S4/5%Co-Pi) best activity, H2 production reaches 3593 μmol·g−1·h−1, approximately double alone. Subsequent characterization data demonstrate introduction facilitates holes, thus improving efficiency carrier separation. This investigation focuses rational utilization high-content rich cocatalysts earth design low-cost efficient catalysts achieve sustainable hydrogen evolution.

Decorating Cd_0.9Zn_0.1S Using a Magnetic FeCo@ N-Doped Graphite Carbon Layer to Achieve Considerable Hydrogen Evolution Efficiency

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(21), P. 8236 - 8246

Published: May 15, 2024

Photocatalytic hydrogen production technology has emerged as one of the most promising technologies to address future energy crisis. Cd0.9Zn0.1S (CZS) is a photocatalyst for visible light activation but limited by slow kinetics photoexcited carrier separation. Density functional theory (DFT) calculations based on first-principles showed that introduction cocatalyst, N-doped graphite carbon (FC@NC), could effectively reduce adsorption free hydrogen, thus accelerating reaction CZS. Supported theoretical predictions, magnetic FC@NC nanoparticles were successfully prepared precipitation and calcination then combined with tetrapod CZS ultrasonic self-assembly form FC@NC/CZS composite Schottky contact. The best mass ratio proved considerable photocatalytic evolution rate up 79.9 ± 0.1 mmol g–1 h–1 under exposure, which was 4.4 times pristine CZS, apparent quantum efficiency (AQE) at 450 nm high 52%. Finally, experimental results DFT calculations, possible mechanism enhanced activity composites heterojunction first proposed. In general, we attribute boosted stable property performance following three aspects: (1) bimetallic alloy cocatalyst easily acts an electron collector, (2) layer protects from oxidation, (3) nitrogen-doped provides more active sites reaction. This work provided green economical technique efficient using in environment.
