Summary: This study systematically investigates the catalytic properties of group 4-6 element oxides, including TiO2, ZrO2, HfO2, V2O5, Ta2O5, CrO3, MoO3, and WO3, on magnesium hydride (MgH2). The dispersion of each oxide on the MgH2 surface is achieved through ball-milling. The hydrogen desorption properties are analyzed, and the oxides on MgH2 are characterized structurally and spectroscopically. Among the oxides, TiO2, V2O5, ZrO2, and CrO3 exhibit higher catalytic activity, enabling hydrogen desorption at around 200°C. The dispersion of the oxides on Mg is found to be closely related to the catalytic process, except for MoO3. Multi oxide states, particularly the 2+ and 3+ oxidation states of transition metals, contribute to the high catalytic activity.

Summary: Microplastics are a emerging pollutant that can enter marine environments like mangrove forests and interfere with the health of the environment and organisms. The concentration of microplastics in sediments is high and fiber and bright color microplastic particles are more common. In addition, mangrove forests exposed to fishing, coastal tourism, urban, and industrial wastewater have higher concentrations of microplastics.
