Conformal carbon nitride thin film inter-active interphase heterojunction with sustainable carbon enhancing sodium storage performance

Abstract

Sustainable, high-performance carbonaceous anode materials are highly required to bring sodium-ion batteries on a more competitive level. Here, we exploit our expertise to control the deposition of a nm-sized conformal...

Turning Polyethylene Waste to Hydrocarbons Using a Sustainable Acidic Carbocatalyst

“…[23][24][25][26][27][28][29][30][31] Such "biorefinery" applications for instance include transesterifications towards biodiesel or the dehydration of glucose to hydroxymethylfurfural (HMF). [29][30][31][32][33] Organic sulfonates are unstable at temperatures exceeding 403 K and can thereby not be used in the current context.…”

“…They are enzyme-inspired but by far more stable than enzymes, and the catalytic sites are carbonconnected organic functionalities, edge and surface terminations, or even just the conjugated pool of electrons of the carbons. [31][32][33][34][35][36] Porous carbons are already found in many environmental applications facing the real world as sorption materials to clean wastewater and air, as filters and fleeces, and they are known to handle environmental realities well. [23][24][25]37,38] Here we present a highly acidic carbocatalyst with a new structure that resolves most of the above-discussed problems, as it is stable up to 773 K in air and 1073 K under N 2 , inert against water and polar impurities, and can even be thermally reactivated.…”

“…For all applications facing water and biological functionality, zeolites are not very favored, and there are countless reported trials to replace them with highly acidic, polymeric ion exchange resins or sulfonated carbons for near‐water catalytic purposes [23–31] . Such “biorefinery” applications for instance include transesterifications towards biodiesel or the dehydration of glucose to hydroxymethylfurfural (HMF) [29–33] . Organic sulfonates are unstable at temperatures exceeding 403 K and can thereby not be used in the current context.…”

“…Carbocatalysts are active catalysts as such. They are enzyme‐inspired but by far more stable than enzymes, and the catalytic sites are carbon‐connected organic functionalities, edge and surface terminations, or even just the conjugated pool of electrons of the carbons [31–36] . Porous carbons are already found in many environmental applications facing the real world as sorption materials to clean wastewater and air, as filters and fleeces, and they are known to handle environmental realities well [23–25,37,38] …”

Exceptional Lithium‐Ion Storage Performance on an Azo‐Bridged Covalent Heptazine Framework

“…[30] More disappointingly, g-C 3 N 4 in composites often performs only as the buffer and dispersant agent, but its own capability realized no improvement. [16,31,32] In other words, composite technology is ineffective to meaningfully modulate the electron mobility of g-C 3 N 4 , which is precisely the most fatal defect for its poor performance. It remains challenging to design such g-C 3 N 4 -based electrode materials with high electron transportability for efficient Li + storage.…”
