Exploring the potential of ZnO–Ag@AgBr/SBA-15 Z-scheme heterostructure for efficient wastewater treatment: synthesis, characterization, and real-world applications

Abstract

This study reports on the synthesis and characterization of ZnO–Ag@AgBr/SBA-15 composites using natural halloysite clay from Yenbai Province, Vietnam, as a silica aluminum source.

Ternary heterogeneous Z-scheme photocatalyst TiO2/CuInS2/OCN incorporated with carbon quantum dots (CQDs) for enhanced photocatalytic degradation efficiency of reactive yellow 145 dye in water

“…Following the formation of reactive species, they contribute to the cleavage of the –SO 3 − group and the C–N bond, yielding intermediate products T1 ( m / z 396.30), T2 ( m / z 292.54), T3 ( m / z 186.07), T4 ( m / z 208.12), T5 ( m / z 163.23), T6 ( m / z 145.52) and T7 ( m / z 110.21). 63,75 These intermediates undergo further oxidation, leading to lower molecular weight products during the cleavage processes with m / z values of T8 ( m / z 274.05), T9 ( m / z 126.23), T10 ( m / z 148.50) and T11 ( m / z 126.23). The LC-MS results show that low molecular weight products such as T12, T13 ( m / z 158.22), T14 ( m / z 118.13), T15 ( m / z 134.16), malonic acid (T16, m / z 104.06), butyric acid (T17, m / z 88.15) and acetic acid (T18, m / z 60.12) are formed during the cleavage process of the intermediate products T8–T11.…”

A green synthesis of CuInS2/MIL-101(Cr) nanocomposite with efficient visible light induced photocatalytic activity

“…The CIS@MIL-101(Cr) sample has a Nyquist plot with a smaller semicircle than that of the MIL-101(Cr) sample indicating an improved charge transfer rate. This result may be due to the strong interaction between the CIS and MIL-101(Cr) phases [45][46][47]. Figure 10(b) shows the photoluminescence (PL) spectra of the CIS, MIL-101(Cr), and CIS@MIL-101(Cr) samples.…”
