Hybrid porous carbon fibers with strong anion-exchangeable functional groups (HACAX) were synthesized by alkylation of pyrolyzed polyacrylonitrile. HACAX exhibits generic stable positively charged functional groups. This expands the applications of porous carbon media for interacting with anions without adjusting pH, such as Cr(vi) adsorption at natural pH.

MoSe2 nanosheets with small size and expanded spaces between the (002) planes were grown on the surfaces of porous N-doped carbon nanotubes (NCNTs) with much higher HER activity than carbon nanotubes without N dopants. Owing to the synergistic effects between the MoSe2 nanosheets and the porous NCNT substrate, MoSe2/NCNTs exhibit superior HER activity to layered metal chalcogenides reported pre...

The adsorption processes of amlodipine onto hydrophilic carbon nanoparticles (Emperor 2000TM) are investigated. The significant increase in voltammetric responses for pre-adsorbed amlodipine compared with those for solution confirms high affinity of amlodipine to carbon nanoparticles (possibly due to π-π stacking interaction between aromatic rings of amlodipine and surface-sulfonated carbon nan...

On page 2057, a Lewis acid porous carbon material with tunable hydrophilicity is prepared by temperature controlled pyrolysis of Al based metal-organic frameworks, by C.-H. Lin, H.-Y. Huang, S. Ma, and co-workers. This porous carbon highlights its low heat capacity, and high water uptake, which acts as efficient laser-absorbing matrix/sorbent for detecting trace levels of target compounds.

Renewable, cost-effective and eco-friendly electrode materials have attracted much attention in the energy conversion and storage fields. Bagasse, the waste product from sugarcane that mainly contains cellulose derivatives, can be a promising candidate to manufacture supercapacitor electrode materials. This study demonstrates the fabrication and characterization of highly porous carbon aerogels...

Large-scale production of active and stable porous carbon catalysts for oxygen reduction reaction (ORR) from protein-rich biomass became a hot topic in fuel cell technology. Here, we report a facile strategy for synthesis of nitrogen-doped porous nanocarbons by means of a simple two-step pyrolysis process combined with the activation of zinc chloride and acid-treatment process, in which kidney ...

In this research, initially, the sol-gel method was employed to produce γ-alumina and TiO2 catalysts with core-shell structure. Iron (III) was used as a dopant. The newlyproduced core-shells were Fe/TiO2// Fe/ γ-Al2O3 (FTFA). Sulfonated cobalt phthalocyanine was used as a dye pollutant in Merox process. By doping Fe in TiO2 catalyst, the ef...

The preparation of porous carbon monoliths with a defined shape via template-assisted routes is reported. Monoliths made from porous concrete and zeolite were each used as the template. The porous concrete-derived carbon monoliths exhibited high gravimetric specific surface areas up to 2000 m²·g-1. The pore system comprised macro-, meso-, and micropores. These pores were hierarchically arranged...

Hybrid carbon films composed of graphene film and porous carbon film may give full play to the advantages of both carbon materials, and have great potential for application in energy storage and conversion devices. Unfortunately, there are very few reports on fabrication of hybrid carbon films. Here we demonstrate a simple approach to fabricate free-standing sandwich-structured hybrid carbon fi...
