Synthesis and characterization of thermoresponsive ZIF-8@PNIPAm-co-MAA microgel composites with enhanced performance as an adsorption/release platform

Allegretto, Juan A.; Giussi, Juan M.; Moya, Sergio E.; Azzaroni, Omar; Rafti, Matias

Composite materials featuring a synergic combination of interesting properties such as stimuli responsiveness and tailored porosity are highly appealing due to their multiple possible applications. We hereby present an example which brings together such features by using poly(N-isopropyl-acrylamide)-derived thermo-responsive microgels and Zn-based Metal Organic Framework (MOF) ZIF-8, capable of…

Novel S-doped ordered mesoporous carbon nanospheres toward advanced lithium metal anodes

Zhang, Fei; Liu, Xiaoyan; Yang, Menghua; Cao, Xiaoqing; Huang, Xingyu; Tian, Yue; Zhang, Fang; Li, Hexing

Lithium metal anode has been considered as an ideal anode for the next generation lithium batteries owing to its high energy density. However, its practical application is still limited by the low Coulombic efficiency and poor safety performance due to the lithium dendrites caused by uncontrollable lithium deposition and unstable…

Influence of Iron Salt Anions on Formation and Oxygen Reduction Activity of Fe/N-Doped Mesoporous Carbon Fuel Cell Catalysts

Fretz, Samuel J.; Janson, Caroline; Rosas-Arbelaez, Walter; Palmqvist, Anders E. C.

Doping carbon materials with transition metal ions can greatly expand their utility, given these metal ions’ unique catalytic activity, for example, in oxygen reduction in proton exchange membrane fuel cells. Unlike main group dopants, a counter anion to the metal cation must be selected and this choice has hitherto received…

Bromomethylation of high-surface area carbons as a versatile synthon: adjusting the electrode–electrolyte interface in lithium–sulfur batteries

Fretz, Samuel J.; Lyons, Christopher T.; Levin, Ella; Chidsey, Christopher E. D.; Palmqvist, Anders E. C.; Stack, T. Daniel P.

A two-step procedure for the surface functionalization of carbon materials has been developed. In the first step, mesoporous carbon (CMK3), carbon black (XC-72R Vulcan), and activated carbon (AC) are bromomethylated efficiently under mild conditions using commercially available reagents, resulting in reproducible surface bromine loadings, the concentrations of which correlate to…

Application of Experimental Design to Hydrogen Storage: Optimisation of Lignin-Derived Carbons

Rowlandson, Jemma L.; Coombs OBrien, James; Edler, Karen J.; Tian, Mi; Ting, Valeska P.

Lignin is a significant by-product of the paper pulping and biofuel industries. Upgrading lignin to a high-value product is essential for the economic viability of biorefineries for bioethanol production and environmentally benign pulping processes. In this work, the feasibility of lignin-derived activated carbons for hydrogen storage was studied using a…

Grafting and stabilization of ordered mesoporous silica COK-12 with graphene oxide for enhanced removal of methylene blue

M. Henning, Laura; Simon, Ulla; Gurlo, Aleksander; J. Smales, Glen; F. Bekheet, Maged

Large-pore ordered mesoporous silica (OMS) COK-12, analogous to the well-known SBA-15, but synthesized in a more environmentally friendly way and exhibiting a shorter plate-like structure, was grafted with different amounts of graphene oxide (GO) for the first time in an inexpensive and rapid process, that was successfully upscaled. Samples were…

Super black materials with extremely low reflectance and high absorption of incident light are crucial in various applications with strict optical requirements. However, the existing super black materials suffer from technical complexity in practical use whereas the underlying physics of their ultralow reflectance is still unclear. Herein, hierarchical porous carbon…

The CoFe2O4 with spinel structure has been identified as a promising anode material of lithium-ion battery because of high theoretical capacity of 914?mAh?g?1, low price, high chemical durability and environmental friendliness. However, the poor electrical conductivity and significant volume change in the charge and discharge process lead to a severe…

A solvent-free porous liquid comprising hollow nanorod–polymer surfactant conjugates

Kumar, Raj; Dhasaiyan, Prabhu; Naveenkumar, Parinamipura M.; Sharma, Kamendra P.

Liquids having permanent porosity can offer significant processing advantages over their solid counterparts. This has recently led to tremendous activity towards the design and development of intrinsic pores in the liquid phase, predominantly for studies involving gas sequestration. We show here the development of a solvent-free mesoporous liquid material based…

Wang, Tianping; Sun, Yanbin; Wu, Jiali; Liu, Xiangyang; Pan, Ruping; Liu, Xikui

The formation of mesostructured polymer and carbon single-crystals is very difficult due to increased complexity of the energy hypersurface and the role of slowed-down kinetics. Here we reported the synthesis of ordered mesostructured phloroglucinol-formaldehyde single crystals through mesoscale self-assembly of reactive monomicelles under acidic conditions which were traditionally thought very…
