Design and synthesis of La3+-, Sb3+-doped MOF-In2S3@FcDc-TAPT COFs hybrid materials with enhanced photocatalytic activity

Covalent organic frameworks: emerging high-performance platforms for efficient photocatalytic applications

“…In particular, Sb 3+ -doped MOF-In 2 S 3 @FcDc-TAPT COFs exhibited a Cr (VI) removal efficiency of 99% within 20 min and the kinetics constant for Cr (VI) reduction was 0.437 min À1 , which was 20-fold higher than that of the non-doped hybrid material and the removal efficiency even had no signicant changes aer 150 days. 138…”

A facile synthesis of highly efficient In2S3 photocatalysts for the removal of cationic dyes with size-dependent photocatalysis

“…The diameter of the semicircle (or arc) in the Nyquist plots at high frequency provided the information on the charge transfer, typically, small diameter represented the low charge transfer resistance ( R ct ). 35 Obviously, In 2 S 3 -10 displayed the lowest R ct in three samples, indicating the fastest charge transfer rate from the photocatalyst to the photoelectrode, 36 which was beneficial to the electron–hole separation.…”

Integration of metal-organic frameworks and covalent organic frameworks: Design, synthesis, and applications

“…The surface of La 3+ -,Sb 3+ -doped MOF-In 2 S 3 many amino groups, which were subjected to an aldehyde condensation reaction with ferrocene-1,1 0 -dicarbaldehyde (FcDc) to form aldehyde-modified MOF, followed by the condensation of a large number of FcDc and 2,4,6-tris(4-aminophenyl)-1,3,5-triazine (TAPT), La 3+ -,Sb 3+ -doped MOF-In 2 S 3 @FcDc-TAPT composites were generated. 48 SEM images show that NH 2 -MIL-68(In) has a uniform rod-like structure with length of 2-3 mm. When the MOFs and COFs materials are hybridized, the size of the rod-like composites increases.…”

“…The as-prepared MOF@COF composites were also investigated by XRD, X-ray photoelectron spectroscopy (XPS), and FTIR, which also indicated the successful preparation of the target structure. 48 Based on the above two approaches, the core-shell MOF@COF composites can be constructed by covalent interaction between amino-functionalized MOFs and COFs. In fact, p-p stacking interaction between MOFs without amino or aldehyde groups and COFs can also provide an opportunity to construct MOF@COF composites due to the aromaticity of MOFs and the ordered p-columnar structure characteristics of COFs, which greatly expands the scope of optional MOFs.…”
