Nano-size calcium peroxide (nCaO2) is an appropriate oxygen source which can meet the needs of in situ chemical oxidation (ISCO) for contaminant remediation from groundwater. In the …

Apr 15, 2018 · Calcium peroxide (CaO 2) is one of the oxygen-releasing compounds and has been applied to magnify the remediation efficacy of polluting areas. In this study, CaO 2 …

Dec 1, 2022 · Further qualitative analysis was evaluated using XRD and XPS. XRD indicated that CaO 2 NPs represented specific peaks (2θ = 30.1°, 35.6°, and 47.3°) [34], demonstrating the …

CaO2 nanoparticles were synthesized by co-precipitation technique and characterised using XRD and FTIR. A mechanism was proposed for adsorption of acrylic acid onto CaO2 nanoparticles …

Jun 1, 2023 · In this work, innovative biochar-loaded CaO 2 was prepared by an in-situ precipitation method. The biochars were modified using base-/acid-treatment to establish the …

X-ray diffraction (XRD) analysis provided insights into the transformation of crystalline phases of CaCO3, starting from aragonite to calcite and eventually to calcium oxide, explaining the...

May 24, 2021 · In this study, fine CaO 2 nanoparticles with Cu–ferrocene molecules at the surface (CaO 2 /Cu–ferrocene) are successfully designed and synthesized. Under an acidic condition, …

The XRD patterns of the as-prepared CaO 2 at all reactant addition rates completely matched the simulated XRD of the orthorhombic CaO 2 structure by Zhao et al. 34 It is concluded that the …

We incorporated calcium peroxide (CaO2)-loaded polycaprolactone (PCL) particles into the PFC-chitosan matrix and subsequently evaluated the release kinetics of O2 and H2O2 from these...

Calcium peroxide (CaO2), which can effectively generate hydrogen peroxide (H2O2) in the absence of oxygen, offers a potential solution to this issue. Many methods have been reported …
