Emerging porous nanosheets: From fundamental synthesis to promising applications

Yun Fan, Jia Zhang, Yu Shen, Bing Zheng, Weina Zhang (✉), and Fengwei Huo (✉)

Based on their different compositions and bonding modes, significant differences have emerged in the applications of metal-organic framework (MOF) and covalent organic framework (COF) nanosheets in various fields, despite of their shared similar properties. Hence, we summarize the recent progress of MOF and COF nanosheets by comparative analysis on their advantages and limitations in synthesis, properties, and applications.

How defects influence the photoluminescence of TMDCs

Mengfan Zhou, Wenhui Wang, Junpeng Lu (✉), and Zhenhua Ni (✉)

We provide a comprehensive review on the fundamental mechanisms of how defects influence the photoluminescence (PL) emission of two-dimensional (2D) transition metal dichalcogenide (TMDC), including radiative/nonradiative recombination kinetics and band structure modification.

Complex RNA–DNA hybrid nanoshapes from iterative mix-andmatch screening

Shi Chen³, Zhiyuan Zhang¹, Eugene Alforque¹, and Thomas Hermann^1,2 (✉)

Ribonucleic acid (RNA)–deoxyribonucleic acid (DNA) hybrid nanoshapes that self-assemble from multiple different nucleic acid building modules provide versatile building blocks for complex materials with features at the sub-10 nm scale. Stable nanoshapes containing multiple different nucleic acid modules were identified by an iterative mix-and-match screening approach from combinations of RNA corner motifs and DNA connectors.

Metallo-aerogels derived from chitosan with encapsulated metal nanoparticles as robust, efficient and selective nanocatalysts towards reduction of nitroarenes

Yajing Shen¹, Qingshu Zheng¹, Jianhong Liu¹, and Tao Tu^1,2,3(✉)

Robust metallo-aerogels consisting of well encapsulated metalnanoparticles (MNPs) by graphite shells were fabricated by pyrolysis of xerometallo-hydrogels derived from chitosan and earth-abundant metal salts (M = Fe, Co, Ni). The metallo-aerogels exhibited high activity and selectivity in the hydrogenation of nitroarenes to anilines with broad substrates scope, good functional group tolerance, and could be recycled for more than 30 runs without obvious loss of activity and selectivity.

Mechanistic insight into gold nanorod transformation in nanoscale confinement of ZIF-8

Cheongwon Bae¹, Jaedeok Lee¹, Lehan Yao², Suhyeon Park¹, Yeonju Lee¹, Jieun Lee¹, Qian Chen^2,3,4,5, and Juyeong Kim¹ (✉)

A gold nanorod core encapsulated by a zeolitic imidazolate framework (ZIF) shows template-dependent behavior in its morphological transformation due to nanoscale confining environment. In the etching event, the nanorod core is spherically carved from its tips, which becomes much slower than in bulk. The regrowth on the spherically etched core inside the ZIF shell gives rise to formation of a raspberry-like branched nanostructure in contrast to the growth of an octahedral shape in bulk condition.
