Summary of "Fabrication of β-phase AgI and BiO co-decorated BiOCO heterojunctions with enhanced photocatalytic performance."

BiOCO was co-decorated by β-phase AgI and BiO forming visible-light-active AgI(β)/BiO(β)-BiOCO composite via simply calcining AgI/BiOCO. The calcination temperature and time played vital role in regulating the structure as well as photocatalytic performance. Optimal AgI(β)/BiO(β)-BiOCO was obtained after 325 C calcination for 2 h with 5% AgI. The ratio of BiO to BiOCO was estimated to be ca. 3:1 on the catalyst surface. The transformation process for n-type BiOCO to p-type BiO(β) was monitored and verified by flat band potential measurements. Due to the presence of p-n junctions between p-type BiO(β), n-type AgI(β) and BiOCO, the optimized ternary composite displayed enhanced photocurrent density and reduced charge transfer resistance, which were beneficial for photocatalytic applications. Despite of decreased specific surface area, dramatically enhanced photocatalytic performance can be observed for simultaneous removal of Cr(VI) and phenol. For example, the estimated k and k on AgI(β)/BiO(β)-BiOCO were 3.3 and 2.2 times relative to those on uncalcined AgI/BiOCO, respectively. The optimized composite also displayed good stability in 4 successive cyclic runs.

Medical and Biotech [MESH] Definitions

The interval between two successive CELL DIVISIONS during which the CHROMOSOMES are not individually distinguishable. It is composed of the G phases (G1 PHASE; G0 PHASE; G2 PHASE) and S PHASE (when DNA replication occurs).

Functionalization of exogenous substances to prepare them for conjugation in PHASE II DETOXIFICATION. Phase I enzymes include CYTOCHROME P450 enzymes and some OXIDOREDUCTASES. Excess induction of phase I over phase II detoxification leads to higher levels of FREE RADICALS that can induce CANCER and other cell damage. Induction or antagonism of phase I detoxication is the basis of a number of DRUG INTERACTIONS.

The period of the CELL CYCLE following DNA synthesis (S PHASE) and preceding M PHASE (cell division phase). The CHROMOSOMES are tetraploid in this point.

The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.

CELL CYCLE regulatory signaling systems that are triggered by DNA DAMAGE or lack of nutrients during G2 PHASE. When triggered they restrain cells transitioning from G2 phase to M PHASE.
