Published: Dec. 20, 2022

Abstract Metal–organic frameworks (MOFs) have emerged as ideal multifunctional platforms for renewable hydrogen (H 2 ) energy applications owing to their tunable chemical compositions and structures high porosity. Their advanced component species porous structure contribute greatly the enhanced activity, electrical conductivity, photo response, charge‐hole separation efficiency, structural stability of MOF materials, which are promising practical H economy. In this review, we mainly introduce design strategies enhancement electro‐/photochemical behaviors or adsorption performance materials production, storage, utilization from compositional perspective. Following these engineering strategies, correlation between composition property‐structure‐performance pristine MOFs composite with components is illustrated. Finally, challenges directions future development related composites economy provided.

Encapsulation of carbon-nanodots into metal-organic frameworks for boosting photocatalytic upcycling of polyvinyl chloride plastic

Applied Catalysis B Environment and Energy, Journal Year: 2023, Volume and Issue: 341, P. 123355 - 123355

Published: Oct. 1, 2023

Although polyvinyl chloride (PVC) ranks as the third most mass-produced synthetic plastic, chemical upcycling of non-biodegradable PVC waste remains a significant challenge. Herein, carbon nanodots combined with metal-organic framework (CDs/Zr-MOF) are fabricated for photocatalytic PVC. Specifically, ultra-small-sized CDs (~2.0 nm) encapsulated into Zr-MOF pores via mild pyrolysis strategy. The maintained MOF structure facilitates charge/mass transfer and improves surface-to-volume ratio active sites CDs. CDs/Zr-MOF exhibits high activity conversion ~76.5% towards acetic acid yield ~14%. mechanism investigation indicates generated •OH radicals can efficiently trigger cleavage C-Cl/C-C bonds Moreover, reduction energy barrier hydroxylation reaction rate-limiting step contributed to improved performance. This work offers feasible method fabricating nanoparticle-embedded MOF-based photocatalysts provides new insights plastics.

An Integrated Plasma–Photocatalytic System for Upcycling of Polyolefin Plastics

ChemSusChem, Journal Year: 2023, Volume and Issue: 16(14)

Published: March 28, 2023

Nondegradable polyolefin plastics, which account for >60 % of total plastic waste, trigger severe global concerns and thus demand effective management technologies. However, owing to the chemical inertness non-polar C-C backbones in structure, efficient upcycling plastics under ambient conditions remains a great challenge. This study introduces an integrated plasma-photocatalytic technology, coupling plasma treatment with solar-driven reforming mild conditions, into value-added hydrogen gaseous fuels. The first step grafts oxygenated groups, such as -OH, O-C=O, C=O, onto chains, leads formation polar hydrophilic polymer that facilitates subsequent photocatalytic step. Therefore, high production activity benchmark efficiency >100 μmol g-1 h-1 was achieved. Moreover, process also demonstrates versatility different including polyethylene, polypropylene polyvinyl chloride. findings provide new avenue sustainable way.
