Carbon Resources Conversion, Год журнала: 2023, Номер 6(4), С. 334 - 351

Опубликована: Март 21, 2023

Hydrogen has attracted widespread attention as a carbon-neutral energy source, but developing efficient and safe hydrogen storage technologies remains huge challenge. Recently, liquid organic carriers (LOHCs) technology shown great potential for stable transport. This allows economical large-scale transoceanic transportation long-cycle storage. In particular, traditional liquids are derived from nonrenewable fossil fuels through costly refining procedures, resulting in unavoidable environmental contamination. Biomass holds promise the preparation of LOHCs due to its unique carbon-balance properties feasibility manufacture aromatic nitrogen-doped compounds. According recent studies, almost 100% conversion 92% yield benzene could be obtained advanced biomass technologies, showing preparing biomass-based LOHCs. Overall, present systems their applications introduced this review, technical paths summarized. Furthermore, paper provides an outlook on future development technology, focusing biomass-derived N-doped compounds

Sustainable chemical upcycling of waste polyolefins by heterogeneous catalysis

SusMat, Год журнала: 2022, Номер 2(2), С. 161 - 185

Опубликована: Апрель 1, 2022

Abstract The mass production of disposable polyolefin products has led to serious plastic pollution and an imbalance between manufacturing recycling. Given these challenges, the chemical upcycling waste polyolefins attracted extensive attention due its high efficiency economic benefits. Herein, we review development in heterogeneous catalysis. status quo recycling is first discussed. We then introduce advanced strategies for view different value‐added discuss their challenges prospects. Our in‐depth analysis centers on catalytic mechanism design principle catalysts. Finally, outlook promising directions facilitate degradation process via polymer catalyst optimized engineering. Innovative are expected promote polyolefins, bringing great promise sustainable society.

Influence of active-site proximity in zeolites on Brønsted acid-catalyzed reactions at the microscopic and mesoscopic levels

Chem Catalysis, Год журнала: 2023, Номер 3(6), С. 100540 - 100540

Опубликована: Март 3, 2023

Zeolites are the catalytic workhorses of various relevant reactions, primarily because their acidic properties. However, there have been few studies on unraveling influence Al distribution acid-catalyzed reactions at mesoscopic and microscopic levels. Taking methanol-to-aromatics (MTA) process as a paradigm, we compared performance two H-ZSM-5 zeolites with comparable properties, except for distribution, i.e., intraparticle proximity nanoscale. Our results demonstrate that enrichment positions closer to external surface in more paired acid sites exhibit enhanced activity than isolated ones. Moreover, such organization accelerates progression cascade yield aromatics alleviate diffusion out. Exploiting this Al-zoning feature, further fabricated hollow by desilication. Combining optimized active improved void-confinement properties crystals highest capacity produce aromatics.
