“…[24] Reportedly, the free electron pairs on the nitrogen atoms in DETA (C4H13N3) can both bind with H + and attract metal ions (e.g., Ni 2+ ), so using DETA can be attempted to remove Ni 2+ from Ni-MOF. [25] Therefore, it is feasible to improve the photocatalytic activity of CdS by compositing the Ni 2+ -removed Ni-MOF derivative with CdS-DETA as a Ni-MOF derivative-CdS-DETA (abbreviated as MOF-CD). And this MOF-based composite photocatalyst does not contain cocatalysts.…”

“…Referring to the relevant literature and combining it with the experimental results (Ni-MOF derivatives do not contain Ni 2+ but still have Ni-MOF functional groups), the hybridized mechanism of the Ni-MOF derivative with CdS-DETA is speculated, as shown in Scheme 2a. Under high-pressure hydrothermal conditions, DETA is protonated to produce positively charged -NR 3 , [13] and DETA reacts with Ni 2+ in Ni-MOF to produce NiDETA 2+ and the Ni-MOF derivative, [25] and NiDETA 2+ is dissolved in a mixed solution of DETA and H 2 O. There is a weak attraction between the negatively charged Ni-MOF derivative and the positively charged Cd 2+ , and Cd 2+ attracts S 2− , while S 2− coordinates with the positively charged -NR 3 .…”
