Study on the twins and textures in CVDZnS

Abstract

In this paper, X-ray diffraction, selective area electron diffraction, and transmission electron microscope (TEM) were used to study the twins at different positions and textures in different direction in CVDZnS. It was found that the CVDZnS twin showed streaks under TEM. The narrower the streaks, the higher the content of twins, and the content of twins in CVDZnS normal layer was higher than that in bright layer. There are textures in CVDZnS, and the main texture of P surface (perpendicular to the direction of growth) is different from S surface (parallel to the growth direction of surface). The main texture in P is {010} 〈001〉, and the S is {101} 〈 131〉.

Review of different series of MOF/g-C3N4 composites for photocatalytic hydrogen production and CO2 reduction

“…Wang et al 107 encapsulated UiO-66-NH 2 by g-C 3 N 4 and then combined with Ti to form a novel composite material. The introduction of Ti can form a Zr-O-Ti mixed metal component with Zr in the MOF to inhibit the recombination of electron holes, thereby improving photocatalytic hydrogen production.…”

Efficient amine oxidation using metal–organic framework photocatalysts for aminoalkyl radical-mediated halogen-atom transfer

“…[31][32][33] For instance, it is a popular strategy to use amine as an electron-donating agent to enhance the photocatalytic performance of MOFs. [34][35][36][37][38][39][40][41][42][43][44][45][46][47] Upon the introduction of amine, the MOF photocatalyst is rapidly regenerated in the reaction owing to back electron transfer, thus enhancing the photocatalytic performance. Reports show that the amine of triethanolamine (TEOA) could be oxidized by MOF-545, 34 UiO-66-NH 2 , 35,36 and MIL-101-NH 2 (Cr/Al) 38,39 serving as sacricial agents to accelerate photocatalytic reactions of CO 2 reduction, hydrogen generation and organic transformations.…”

In addition, other amines of triethylamine (TEA) and N,N-diisopropylethylamine (DIPEA) have been examined as sacricial electron-donating agents for MIL-125, 40 Cd-TCPP, 41 Zn-PDI, 42 MOF-525, 43 MOF-520, 44 UNLPF-12, 45 PCN-99 46 and UiO-67.…”
