Influence of phosphate on deposition and detachment of TiO

Zhan Wang, Chongyang Shen, Yichun Du, Yulong Zhang, Baoguo Li

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 5, doi: 10.1007/s11783-019-1163-y

Abstract: Deposition was reduced at higher pH and by adsorption of phosphate in soil.Surface roughness and charge heterogeneity play a role in the deposition/ release.However, the influence of phosphate on deposition/release— and thereby on transport— of TiO2 NPs in soilResults show that the deposition of TiO2 NPs decreased with decreasing IS, increasing pH, and when soilAccordingly, both primary- and secondary-minimum deposition were inhibited.

A density functional theory study of methane activation on MgO supported NiM cluster: role of M on C–H

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 10, Pages 1485-1492 doi: 10.1007/s11705-022-2169-8

Abstract: In present work, methane activation on MgO supported Ni–M (M = Fe, Co, Cu, Pd, Pt) cluster was exploredthrough detailed density functional theory calculations, compared to pure Ni cluster.CH₄ adsorption on Cu promoted Ni cluster requires overcoming an energy of 0.07 eV, indicatingDoping elements of the same period in Ni cluster, such as Fe, Co and Cu, for C–H bond activation followsConsequently, C–H bond activation demands a lower energy barrier on Ni–Pt cluster.
